Leadership Lifelines: Prayer, Fasting, and Flexibility

How discipline and commitment prove essential in your leadership ministry.

Andy Stanley said, “Leadership is stewardship, and you are accountable,” while speaking to a group of leaders at Catalyst Atlanta in 2006. This quote absolutely resonated with me, because we can forget that as leaders we are responsible for our own leadership. Not only are we accountable to ourselves and those we lead, but most importantly we are accountable to the God that called us to lead.

Leadership in its most basic definition is the action or ability to lead a group or organization. Having been in leadership in education, business, the nonprofit sector, and ministry, I know all too well the truth of this statement. You are only a leader if someone is following you, so we need to give attention to how we lead, the impact of our leadership, and the health of our leadership.

Leading effectively requires discipline, and I have learned I am most effective when I discipline myself. As a leader, I have found three disciplines that help me lead well and avoid leadership pitfalls and burnout. I have used these in every area I have been called to lead. These lifelines have proven viable, having saved my life and the lives entrusted to me. Through the lifelines of prayer, fasting, and flexibility, my leadership has been enhanced in multiple ways. Albeit, prayer, fasting, and flexibility are disciplines, I consider them lifelines because of the life-giving power they have provided.

The lifeline of prayer

We know the power in prayer. We can perform a historical analysis of scripture and see many of the leaders God used were given to prayer. Prayer is what brings our will into alignment with God’s will. Whether God calls us to lead in church or the marketplace, our prayer lives are essential to our success as leaders. ...

Getting to the Heart of Digital Accessibility

Quick! Think of the word “developer” or “coder” — what’s the first thing that comes to mind? Maybe a whiteish male in his twenties living in a busy metropolis, wearing a nerdy t-shirt and hoodie? Someone a bit like Mark Zuckerberg? Or maybe a younger Bill Gates or Sergey Brin? Any of the dudes from the HBO series Silicon Valley, perhaps? Certainly no one like me.

By tech standards, I’m old. I’m also female and a mother. I live in a midwestern town you’ve never heard of and will never visit — a town where the cows vastly outnumber the people. My hair color is (almost) natural and is no longer part of the ROYGBIV collection, so I have no perceived conference street cred. I own about a thousand geeky T-shirts, but never actually wear them in public, opting for more “girly” attire (or so was pointed out by a male colleague). On the surface, I look more suited to taking notes at a PTA meeting than writing code. I’m a bit of an outsider. A tech misfit.

So when my 11-year-old daughter finished her recent coding camp and excitedly declared, “Now I’m a real developer, Mom, just like you!” there was the usual parent pride, but also a small piece of me that cringed. Because, as much as I support the STEM fields, and want the next generation of girls to be coding wizard-unicorn-ninjas, I really don’t want my own daughter to be a developer. The rationale behind this bold (and maybe controversial) statement comes from a place of protection. The tech world we live in today is far from perfect. I’ve endured my share of misogyny, self-doubt, and sexual harassment. Why wouldn’t I want to protect her from all of that?

The (diversity) elephant in the (computer) room

You’ve heard this story before: there is not enough diversity in tech. This puzzling trend seems to continue year after year, even though numerous studies show that by including more people from underrepresented communities, a company can increase its innovation, employee retention, and bottom line. Even with the recent push and supposed support for diversity and inclusivity from many Fortune 500 companies, women and female-identifying people still only hold 20% of all top tech jobs.

The data from FY 2018 shows that the number of women in technical roles at three of the top tech giants was 24% for Adobe, 26% for Google, and 22% for Facebook. While these numbers show that there is still not enough representation for women, these numbers do reflect a slight increase from the previous year (FY 2017: Adobe 22%, Google 25%, Facebook 15%). But even with this upward trend of hiring women in tech roles, the marginal growth rate has not caught up with the real world. The tech workforce is seriously out of touch with reality if, in 2019, a demographic (women) that represents more than half the global population is still considered a minority.

Sometimes this lack of diversity at the top level is blamed on a “pipeline” issue. The logic being: “If there are not enough girls who learn to code, then there will not be enough women who can code.” However, programs aimed at teaching girls how to code have skyrocketed in the past few years. Girls now make up about half of the enrollment in high-school coding classes and are scoring almost identically to their male classmates on standardized math and science tests, yet, young women make up only 18% of all Computer Science degrees. I have to wonder if this steep drop in interest has more to do with lack of representation in the tech sphere, than with girls and young women simply not being “smart enough” or “not interested” in working with code? At the very least, the lack of representation certainly doesn’t help.

Of course, the diversity picture becomes even more abysmal when you consider other underrepresented groups such as people of color, people from the LGBTQ community, and people with disabilities. And while I really don’t like glossing over these deeper diversity issues in tech, because they are abundant and are much more grotesque failings than the male/female ratio, I also don’t feel qualified to speak about these issues. I encourage you to look to and value the voices of others who can speak with higher authority on these deeper diversity issues, such as Ire Aderinokun, Taelur Alexis, Imani Barbarin, Angie Jones, Fatima Khalid, Tatiana Mac, Charlie Owen, Cherry Rae, and so many others. And for those readers who are new to the topic of diversity in tech, watch Tatiana Mac’s recent conference talk How Privilege Defines Performance — it’s well worth the 35 minutes of your life.

The four stages in the digital accessibility journey

However you look at it, the numbers don’t lie. There are some pretty significant diversity issues in tech. So how do we fix this issue before the next wave of young developers join the tech workforce? Simple: teach developers to write accessible code.

This may seem like a joke to some and stretch to others, but hear me out. When we talk about accessible code, what we are really talking about at its core is inclusiveness. The actual process of writing accessible code involves rules and standards, tests and tools; but inclusive development is more abstract than that. It’s a shift in thinking. And when we rethink our approach to development, we go beyond just the base level of simple code functionality. We instead think, how is this code consumed? How can we make it even more intelligible and easier for people to use? Inclusive development means making something valuable, not just accessible, to as many people as we can.

That line of thinking is a bit abstract, so let’s go through an example. Let’s say you are tasked with updating the color contrast between the text on a webpage or app and the background. What happens at each stage in the accessibility journey?

Stage 1: Awareness — You are brand new to digital accessibility and are still trying to understand what it is and how you can implement changes in your daily workflow. You may be aware that there is a set of digital accessibility guidelines that other developers follow, but you are a bit hazy on what it all means in a practical sense.

Stage 2: Knowledge — You know a bit more about digital accessibility and feel comfortable using a few testing tools, so you run an automated accessibility test on your website and it flags a possible issue with the color contrast. Based on your awareness of the guidelines, you know the color contrast ratio between the text and the background needs to be a certain number and that you need a tool to test this.

Stage 3: Practice — Feeling more confident in your knowledge of digital accessibility rules and best practices, you use a tool to measure the color contrast ratio between the text and the background. Then based on the output of the tool, you modify the hex code to meet the color contrast ratio guidelines and retest to confirm you have met the accessibility requirements for this issue.

Stage 4: Understanding — You understand that the accessibility guidelines and tools are created with people in mind, and that code is secondary to all of that. One is the means, and the other is the end. In the color contrast example, you understand that people with low-vision or colorblindness need these color contrast changes in order to actually see the words on your web page.

This is a bit of an oversimplification of the process. But I hope you get the gist — that there are different stages of digital accessibility knowledge and understanding. True beginners may not be to even stage one, but I am finding that group rarer and rarer these days. The word about digital accessibility seems to be out! Which is great; but that’s only the first hurdle. What I’m seeing now is that a lot of people stop at Stage 2: Knowledge or Stage 3: Practice — where you are aware of the digital accessibility guidelines, have some testing tools in your back pocket, and know how to fix some of the issues reported, but haven’t quite connected the dots to the humans they impact.

From the standpoint of getting daily stuff done, stages two and three are okay stopping points. But what happens when the things you need to do are too complex for a quick fix, or you have no buy-in from your peers or management? I feel that once we get to Stage 4: Understanding, and really get why these kinds of changes are needed, people will be more motivated to make those changes regardless of the challenges involved. When you arrive at stage four, you have gone beyond knowing the basic rules, testing, and coding. You recognize that digital accessibility is not just a “nice to have” but a “must have” and it becomes about quality of life for real people. This is digital inclusion. This is something you can’t unsee, you can’t unlearn, and you can’t ignore.

Making digital accessibility a priority — not a requirement

In my role as an accessibility trainer, I like to kick-off each session with the question: “What are you hoping to learn today about digital accessibility?” I ask this question to establish a rapport with the audience and to understand where everyone is in their accessibility journey, but I am also evaluating the level of company and individual buy-in too. There is nothing worse than showing up to teach a group that does not care to be taught. If I hear the words “I am only here because I have to be” — I know it will be an uphill battle to get them anywhere close to Stage 4: Understanding, so I mentally regroup and aim for another stage.

In my experience, when companies and their leaders say “Digital accessibility is a requirement,” nine times out of ten there is a motivating factor behind this sweeping declaration (for example, impending litigation, or at least the fear of it). When changes are framed as mandatory and packaged as directives from on high with little additional context, people can be resistant and will find excuses to fight or challenge the declaration, and any change can become an uphill battle. Calling something “mandatory” only speaks to Stage 1: Awareness.

By swapping out one word from the original declaration and saying “Digital accessibility is a priority,” companies and their leaders have reframed the conversation with their employees. When changes are framed as “working towards a solution” and discussed openly and collaboratively, people feel like they are part of the process and are more open to embracing change. In the long run, embracing change becomes part of a company’s culture and leads to innovation (and, yes, inclusion) on all levels. Calling something a priority speaks to Stage 4: Understanding.

Some of the excuses I often hear from clients for not prioritizing accessibility is that it is too difficult, too costly, and/or too time consuming — but is that really the case? In the same accessibility training, I lead an exercise where we look at a website with an accessibility testing tool and review any issues that came up. With the group’s help we plot out the “impact to user” versus the “remediation effort” on the part of the team. From group to group, while the plots are slightly different, one commonality is that close to 80% of the errors plotted fall into the quadrant of “simple to fix” for the team, but they also fall under “high impact” to the user. Based on this empirical data, I won’t buy the argument from clients who say that accessibility is too difficult and costly and time consuming anymore. It comes down to whether it’s a priority — for each individual and for the company as a whole.

What will your coding legacy be?

The infinite monkey theorem states that a monkey hitting keys at random on a typewriter for an infinite amount of time will eventually type any given text, such as the complete works of William Shakespeare. So by that same logic, a programmer hitting keys at random on a computer for an infinite amount of time will almost surely produce a website that is accessible. But where is the thought process? Where is the human element? While all the things we’ve already talked about — awareness, education, and prioritization of accessibility are important steps in making the digital world more inclusive to all — without intent, we are just going to keep randomly tapping away at our computers, repeating the same mistakes over and over again. The intent behind the code has to be part of the process, otherwise accessibility is just another task that has no meaning.

Maybe I’m naive, but I’d like to think we’ve come to a point in our society where we want our work lives to have meaning. And that we don’t want to just hear about the positive change that is happening, but want to be part of the change. Digital accessibility is a place where this can happen! Not only does understanding and writing purpose-driven code help people with disabilities in the short-run, I believe strongly that is key to solving the overarching diversity issue in tech in the long-run. Developers who reach Stage 4: Understanding, and who prioritize accessible code because they understand it’s fundamentally about people, will also be the ones who help create and cultivate an inclusive environment where people from more diverse backgrounds are also prioritized and accepted in the tech world.

Because when you strip away all the styles, all the mark-up, all the cool features from a website or app — what’s left? People. And honestly, the more I learn about digital accessibility, the more I realize it’s not about the code at all. Digital accessibility is rooted in the user; and, while I (and countless others) can certainly teach you how to write accessible code, and build you tools, patterns, and libraries to use, I realize we can’t teach you to care. That is a choice you have to make yourself. So think for a moment — what are you leaving the next generation of developers with all that inaccessible code you haven’t given much thought to? Is it the coding legacy you really want to leave? I challenge you to do better for my daughter, her peers, and for the countless others who are not fully represented in the tech community today.

The Untapped Power of Vulnerability & Transparency in Content Strategy

In marketing, transparency and vulnerability are unjustly stigmatized. The words conjure illusions of being frightened, imperfect, and powerless. And for companies that shove carefully curated personas in front of users, little is more terrifying than losing control of how people perceive the brand.

Let’s shatter this illusioned stigma. Authentic vulnerability and transparency are strengths masquerading as weaknesses. And companies too scared to embrace both traits in their content forfeit bona fide user-brand connections for often shallow, misleading engagement tactics that create fleeting relationships.

Transparency and vulnerability are closely entwined concepts, but each one engages users in a unique way. Transparency is how much information you share, while vulnerability is the truth and meaning behind your actions and words. Combining these ideas is the trick to creating empowering and meaningful content. You can’t tell true stories of vulnerability without transparency, and to be authentically transparent you must be vulnerable.

To be vulnerable, your brand and its content must be brave, genuine, humble, and open, all of which are traits that promote long-term customer loyalty. And if you’re transparent with users about who you are and about your business practices, you’re courting 94 percent of consumers who say they’re more loyal to brands that offer complete openness and 89 percent of people who say they give transparent companies a second chance after a bad experience.

For many companies, being completely honest and open with their customers—or employees, in some cases—only happens in a crisis. Unfortunately for those businesses, using vulnerability and transparency only as a crisis management strategy diminishes how sincere they appear and can reduce customer satisfaction.

Unlocking the potential of being transparent and vulnerable with users isn’t a one-off tactic or quick-fix emergency response tool—it’s a commitment to intimate storytelling that embraces a user’s emotional and psychological needs, which builds a meaningful connection between the storyteller and the audience.

The three storytelling pillars of vulnerable and transparent content

In her book, Braving the Wilderness, sociologist Brené Brown explains that vulnerability connects us at an emotional level. She says that when we recognize someone is being vulnerable, we invest in their story and begin to develop an emotional bond. This interwoven connection encourages us to experience the storyteller’s joy and pain, and then creates a sense of community and common purpose among the person being vulnerable and the people who acknowledge that vulnerability.

Three pillars in a company’s lifecycle embrace this bond and provide an outline for telling stories worthy of a user’s emotional investment. The pillars are:

  • the origins of a company, product, idea, or situation;
  • intimate narratives about customers’ life experiences;
  • and insights about product success and failure.

Origin stories

An origin story spins a transparent tale about how a company, product, service, or idea is created. It is often told by a founder, CEO, or industry innovator. This pillar is usually used as an authentic way to provide crisis management or as a method to change how users feel about a topic, product, or your brand.

Customers’ life experiences

While vulnerable origin stories do an excellent job of making users trust your brand, telling a customer’s personal life story is arguably the most effective way to use vulnerability to entwine a brand with someone’s personal identity.

Unlike an origin story, the customer experiences pillar is focused on being transparent about who your customers are, what they’ve experienced, and how those journeys align with values that matter to your brand. Through this lens, you’ll empower your customers to tell emotional, meaningful stories that make users feel vulnerable in a positive way. In this situation, your brand is often a storytelling platform where users share their story with the brand and fellow customers.

Product and service insights

Origin stories make your brand trustworthy in a crisis, and customers’ personal stories help users feel an intimate connection with your brand’s persona and mission. The last pillar, product and service insights, combines the psychological principles that make origin and customer stories successful. The outcome is a vulnerable narrative that rallies users’ excitement about, and emotional investment in, what a company sells or the goals it hopes to achieve.

Vulnerability, transparency, and the customer journey

The three storytelling pillars are crucial to embracing transparency and vulnerability in your content strategy because they let you target users at specific points in their journey. By embedding the pillars in each stage of the customer’s journey, you teach users about who you are, what matters to you, and why they should care.

For our purposes, let’s define the user journey as:

  • awareness;
  • interest;
  • consideration;
  • conversion;
  • and retention.

Awareness

People give each other seven seconds to make a good first impression. We’re not so generous with brands and websites. After discovering your content, users determine if it’s trustworthy within one-tenth of a second.

Page design and aesthetics are often the determining factors in these split-second choices, but the information users discover after that decision shapes their long-term opinions about your brand. This snap judgement is why transparency and vulnerability are crucial within awareness content.

When you only get one chance to make a positive first impression with your audience, what content is going to be more memorable?

Typical marketing “fluff” about how your brand was built on a shared vision and commitment to unyielding customer satisfaction and quality products? Or an upfront, authentic, and honest story about the trials and tribulations you went through to get where you are now?

Buffer, a social media management company that helped pioneer the radical transparency movement, chose the latter option. The outcome created awareness content that leaves a positive lasting impression of the brand.

In 2016, Joel Gascoigne, cofounder and CEO of Buffer, used an origin story to discuss the mistakes he and his company made that resulted in laying off 10 employees.

In the blog post “Tough News: We’ve Made 10 Layoffs. How We Got Here, the Financial Details and How We’re Moving Forward,” Gascoigne wrote about Buffer’s over-aggressive growth choices, lack of accountability, misplaced trust in its financial model, explicit risk appetite, and overenthusiastic hiring. He also discussed what he learned from the experience, the changes Buffer made based on these lessons, the consequences of those changes, and next steps for the brand.

Gascoigne writes about each subject with radical honesty and authenticity. Throughout the article, he’s personable and relatable; his tone and voice make it obvious he’s more concerned about the lives he’s irrevocably affected than the public image of his company floundering. Because Gascoigne is so transparent and vulnerable in the blog post, it’s easy to become invested in the narrative he’s telling. The result is an article that feels more like a deep, meaningful conversation over coffee instead of a carefully curated, PR-approved response.

Yes, Buffer used this origin story to confront a PR crisis, but they did so in a way that encouraged users to trust the brand. Buffer chose to show up and be seen when they had no control over the outcome. And because Gascoigne used vulnerability and transparency to share the company’s collective pain, the company reaped positive press coverage and support on social media—further improving brand awareness, user engagement, and customer loyalty.

However, awareness content isn’t always brand focused. Sometimes, smart awareness content uses storytelling to teach users and shape their worldviews. The 2019 State of Science Index is an excellent example.

The annual State of Science Index evaluates how the global public perceives science. The 2019 report shows that 87 percent of people acknowledge that science is necessary to solve the world’s problems, but 33 percent are skeptical of science and believe that scientists cause as many problems as they solve. Furthermore, 57 percent of respondents are skeptical of science because of scientists’ conflicting opinions about topics they don’t understand.

3M, the multinational science conglomerate that publishes the report, says the solution for this anti-science mindset is to promote intimate storytelling among scientists and layfolk.

3M creates an origin story with its awareness content by focusing on the ins and outs of scientific research. The company is open and straightforward with its data and intentions, eliminating any second guesses users might have about the content they’re digesting.

The company kicked off this strategy on three fronts, and each storytelling medium interweaves the benefits of vulnerability and transparency by encouraging researchers to tell stories that lead with how their findings benefit humanity. Every story 3M tells focuses on breaking through barriers the average person faces when they encounter science and encouraging scientists to be vulnerable and authentic with how they share their research.

First, 3M began a podcast series known as Science Champions. In the podcast, 3M Chief Science Advocate Jayshree Seth interviews scientists and educators about the global perception of science and how science and scientists affect our lives. The show is currently in its second season and discusses a range of topics in science, technology, engineering, and math.

Second, the company worked with science educators, journalist Katie Couric, actor Alan Alda, and former NASA astronaut Scott Kelly to develop the free Scientists as Storytellers Guide. The ebook helps STEM researchers improve how and why they communicate their work with other people—with a special emphasis on being empathetic with non-scientists. The guide breaks down how to develop communications skills, overcome common storytelling challenges, and learn to make science more accessible, understandable, and engaging for others.

Last, 3M created a film series called Beyond the Beaker that explores the day-to-day lives of 3M scientists. In the short videos, scientists give the viewer a glimpse into their hobbies and home life. The series showcases how scientists have diverse backgrounds, hobbies, goals, and dreams.

Unlike Buffer, which benefits directly from its awareness content, 3M’s three content mediums are designed to create a long-term strategy that changes how people understand and perceive science, by spreading awareness through third parties. It’s too early to conclude that the strategy will be successful, but it’s off to a good start. Science Champions often tops “best of” podcast lists for science lovers, and the Scientists as Storytellers Guide is a popular resource among public universities.

Interest

How do you court new users when word-of-mouth and organic search dominate how people discover new brands? Target their interests.

Now, you can be like the hundreds of other brands that create a “10 best things” list and hope people stumble onto your content organically and like what they see. Or, you can use content to engage with people who are passionate about your industry and have genuine, open discussions about the topics that matter to you both.

The latter option is a perfect fit for the product and service insights pillar, and the customers’ life experiences pillar.

To succeed in these pillars you must balance discussing the users’ passions and how your brand plays into that topic against appearing disingenuous or becoming too self-promotional.

Nonprofits have an easier time walking this taut line because people are less judgemental when engaging with NGOs, but it’s rare for a for-profit company to achieve this balance. SpaceX and Thinx are among the few brands that are able to walk this tightrope.

Thinx, a women’s clothing brand that sells period-proof underwear, uses its blog to generate awareness, interest, and consideration content via the customers’ life experiences pillar. The blog, aptly named Periodical, relies on transparency and vulnerability as a cornerstone to engage users about reproductive and mental health.

Toni Brannagan, Thinx’s content editor, says the brand embraces transparency and vulnerability by sharing diverse ideas and personal experiences from customers and experts alike, not shying away from sensitive subjects and never misleading users about Thinx or the subjects Periodical discusses.

As a company focused on women’s healthcare, the product Thinx sells is political by nature and entangles the brand with themes of shame, cultural differences, and personal empowerment. Thinx’s strategy is to tackle these subjects head-on by having vulnerable conversations in its branding, social media ads, and Periodical content.

“Vulnerability and transparency play a role because you can’t share authentic diverse ideas and experiences about those things—shame, cultural differences, and empowerment—without it,” Brannagan says.

A significant portion of Thinx’s website traffic is organic, which means Periodical’s interest-driven content may be a user’s first touchpoint with the brand.

“We’ve seen that our most successful organic content is educational, well-researched articles, and also product-focused blogs that answer the questions about our underwear, in a way that’s a little more casual than what’s on our product pages,” Brannagan says. “In contrast, our personal essays and ‘more opinionated’ content performs better on social media and email.”

Thanks in part to the blog’s authenticity and open discussions about hard-hitting topics, readers who find the brand through organic search drive the most direct conversions.

Conversations with users interested in the industry or topic your company is involved in don’t always have to come from the company itself. Sometimes a single person can drive authentic, open conversations and create endearing user loyalty and engagement.

For a company that relies on venture capital investments, NASA funding, and public opinion for its financial future, crossing the line between being too self-promotional and isolating users could spell doom. But SpaceX has never shied away from difficult or vulnerable conversations. Instead, the company’s founder, Elon Musk, embraces engaging with users interests in public forums like Twitter and press conferences.

Musk’s tweets about SpaceX are unwaveringly authentic and transparent. He often tweets about his thoughts, concerns, and the challenges his companies face. Plus, Musk frequently engages with his Twitter followers and provides candid answers to questions many CEOs avoid discussing. This authenticity has earned him a cult-like following.

Musk and SpaceX create conversations that target people’s interests and use vulnerability to equally embrace failure and success. Both the company and its founder give the public and investors an unflinching story of space exploration.

And despite laying off 10 percent of its workforce in January of 2019, SpaceX is flourishing. In May 2019, its valuation had risen to $33.3 billion and reported annual revenue exceeded $2 billion. It also earned global media coverage from launching Musk’s Tesla Roadster into space, recently completed a test flight of its Crew Dragon space vehicle, and cemented multiple new payload contracts.

By engaging with users on social media and through standard storytelling mediums, Thinx and SpaceX bolster customer loyalty and brand engagement.

Consideration

Modern consumers argue that ignorance is not bliss. When users are considering converting with a brand, 86 percent of consumers say transparency is a deciding factor. Transparency remains crucial even after they convert, with 85 percent of users saying they’ll support a transparent brand during a PR crisis.

Your brand must be open, clear, and honest with users; there is no longer another viable option.

So how do you remain transparent while trying to sell someone a product? One solution employed by REI and Everlane is to be openly accountable to your brand and your users via the origin stories and product insights pillars.

REI, a national outdoor equipment retailer, created a stewardship program that behaves as a multifaceted origin story. The program’s content highlights the company’s history and manufacturing policies, and it lets users dive into the nitty-gritty details about its factories, partnerships, product production methods, manufacturing ethics, and carbon footprint.

REI also employs a classic content hub strategy to let customers find the program and explore its relevant information. From a single landing page, users can easily find the program through the website’s global navigation and then navigate to every tangential topic the program encompasses.

REI also publishes an annual stewardship report, where users can learn intimate details about how the company makes and spends its money.

Everlane, a clothing company, is equally transparent about its supply chain. The company promotes an insider’s look into its global factories via product insights stories. These glimpses tell the personal narratives of factory employees and owners, and provide insights into the products manufactured and the materials used. Everlane also published details of how they comply with the California Transparency in Supply Chains Act to guarantee ethical working conditions throughout its supply chain, including refusing to partner with human traffickers.

The crucial quality that Everlane and REI share is they publicize their transparency and encourage users to explore the shared information. On each website, users can easily find information about the company’s transparency endeavors via the global navigation, social media campaigns, and product pages.

The consumer response to transparent brands like REI and Everlane is overwhelmingly positive. Customers are willing to pay price premiums for the additional transparency, which gives them comfort by knowing they’re purchasing ethical products.

REI’s ownership model has further propelled the success of its transparency by using it to create unwavering customer engagement and loyalty. As a co-op where customers can “own” part of the company for a one-time $20 membership fee, REI is beholden to its members, many of which pay close attention to its supply chain and the brands REI partners with.

After a deadly school shooting in Parkland, Florida, REI members urged the company to refuse to carry CamelBak products because the brand’s parent company manufactures assault-style weapons. Members argued the partnership violated REI’s supply chain ethics. REI listened and halted orders with CamelBak. Members rejoiced and REI earned a significant amount of positive press coverage.

Conversion

Imagine you’ve started incorporating transparency throughout your company, and promote the results to users. Your brand also begins engaging users by telling vulnerable, meaningful stories via the three pillars. You’re seeing great engagement metrics and customer feedback from these efforts, but not much else. So, how do you get your newly invested users to convert?

Provide users with a full-circle experience.

If you combine the three storytelling pillars with blatant transparency and actively promote your efforts, users often transition from the consideration stage into the conversion state. Best of all, when users convert with a company that already earned their trust on an emotional level, they’re more likely to remain loyal to the brand and emotionally invested in its future.

The crucial step in combining the three pillars is consistency. Your brand’s stories must always be authentic and your content must always be transparent. The outdoor clothing brand Patagonia is among the most popular and successful companies to maintain this consistency and excel with this strategy.

Patagonia is arguably the most vocal and aggressive clothing retailer when it comes to environmental stewardship and ethical manufacturing.

In some cases, the company tells users not to buy its clothing because rampant consumerism harms the environment too much, which they care about more than profits. This level of radical transparency and vulnerability skyrocketed the company’s popularity among environmentally-conscious consumers.

In 2011, Patagonia took out a full-page Black Friday ad in the New York Times with the headline “Don’t Buy This Jacket.” In the ad, Patagonia talks about the environmental toll manufacturing clothes requires.

“Consider the R2 Jacket shown, one of our best sellers. To make it required 135 liters of water, enough to meet the daily needs (three glasses a day) of 45 people. Its journey from its origin as 60 percent recycled polyester to our Reno warehouse generated nearly 20 pounds of carbon dioxide, 24 times the weight of the finished product. This jacket left behind, on its way to Reno, two-thirds [of] its weight in waste.”

The ad encourages users to not buy any new Patagonia clothing if their old, ratty clothes can be repaired. To help, Patagonia launched a supplementary subdomain to its e-commerce website to support its Common Thread Initiative, which eventually got rebranded as the Worn Wear program.

Patatgonia’s Worn Wear subdomain gets users to engage with the company about causes each party cares about. Through Worn Wear, Patagonia will repair your old gear for free. If you’d rather have new gear, you can instead sell the worn out clothing to Patagonia, and they’ll repair it and then resell the product at a discount. This interaction encourages loyalty and repeat brand-user engagement.

In addition, the navigation on Patagonia’s main website practically begs users to learn about the brand’s non-profit initiatives and its commitment to ethical manufacturing.

Today, Patagonia is among the most respected, profitable, and trusted consumer brands in the United States.

Retention

Content strategy expands through nearly every aspect of the marketing stack, including ad campaigns, which take a more controlled approach to vulnerability and transparency. To target users in the retention stage and keep them invested in your brand, your goal is to create content using the customers’ life experiences pillar to amplify the emotional bond and brand loyalty that vulnerability creates.

Always took this approach and ended up with one of its most successful social media campaigns.

In June 2014, Always launched its #LikeAGirl campaign to empower adolescent and teenage girls by transforming the phrase “like a girl” from a slur into a meaningful and positive statement.

The campaign is centered on a video in which Always tasked children, teenagers, and adults to behave “like a girl” by running, punching, and throwing while mimicking their perception of how a girl performs the activity. Young girls performed the tasks wholeheartedly and with gusto, while boys and adults performed overly feminine and vain characterizations. The director then challenged the person on their portrayal, breaking down what doing things “like a girl” truly means. The video ends with a powerful, heart-swelling statement:

“If somebody else says that running like a girl, or kicking like a girl, or shooting like a girl is something you shouldn’t be doing, that’s their problem. Because if you’re still scoring, and you’re still getting to the ball in time, and you’re still being first...you’re doing it right. It doesn’t matter what they say.”

This customer story campaign put the vulnerability girls feel during puberty front and center so the topic would resonate with users and give the brand a powerful, relevant, and purposeful role in this connection, according to an Institute for Public Relations campaign analysis.

Consequently, the #LikeAGirl campaign was a rousing success and blew past the KPIs Always established. Initially, Always determined an “impactful launch” for the video meant 2 million video views and 250 million media impressions, the analysis states.

Five years later, the campaign video has more than 66.9 million views and 42,700 comments on YouTube, with more than 85 percent of users reacting positively. Here are a few additional highlights the analysis document points out:

  • Eighty-one percent of women ages 16–24 support Always in creating a movement to reclaim “like a girl” as a positive and inspiring statement.
  • More than 1 million people shared the video.
  • Thirteen percent of users created user-generated content about the campaign.
  • The #LikeAGirl program achieved 4.5 billion global impressions.
  • The campaign received 290 million social impressions, with 133,000 social mentions, and it caused a 195.3 percent increase in the brand’s Twitter followers.

Among the reasons the #LikeAGirl content was so successful is that it aligned with Brené Brown’s concept that experiencing vulnerability creates a connection centered on powerful, shared emotions. Always then amplified the campaign’s effectiveness by using those emotions to encourage specific user behavior on social media.

How do you know if you’re making vulnerable content?

Designing a vulnerability-focused content strategy campaign begins by determining what kind of story you want to tell, why you want to tell it, why that story matters, and how that story helps you or your users achieve a goal.

When you’re brainstorming topics, the most important factor is that you need to care about the stories you’re telling. These tales need to be meaningful because if you’re weaving a narrative that isn’t important to you, it shows. And ultimately, why do you expect your users to care about a subject if you don’t?

Let’s say you’re developing a content campaign for a nonprofit, and you want to use your brand’s emotional identity to connect with users. You have a handful of possible narratives but you’re not sure which one will best unlock the benefits of vulnerability. In a Medium post about telling vulnerable stories, Cayla Vidmar presents a list of seven self-reflective questions that can reveal what narrative to choose and why.

If you can answer each of Vidmar’s questions, you’re on your way to creating a great story that can connect with users on a level unrivaled by other methods. Here’s what you should ask yourself:

  • What meaning is there in my story?
  • Can my story help others?
  • How can it help others?
  • Am I willing to struggle and be vulnerable in that struggle (even with strangers)?
  • How has my story shaped my worldview (what has it made me believe)?
  • What good have I learned from my story?
  • If other people discovered this good from their story, would it change their lives?

While you’re creating narratives within the three pillars, refer back to Vidmar’s list to maintain the proper balance between vulnerability and transparency.

What’s next?

You now know that vulnerability and transparency are an endless fountain of strength, not a weakness. Vulnerable content won’t make you or your brand look weak. Your customers won’t flee at the sight of imperfection. Being human and treating your users like humans isn’t a liability.

It’s time for your brand to embrace its untapped potential. Choose to be vulnerable, have the courage to tell meaningful stories about what matters most to your company and your customers, and overcome the fear of controlling how users will react to your content.

Origin story

Every origin story has six chapters:

  • the discovery of a problem or opportunity;
  • what caused this problem or opportunity;
  • the consequences of this discovery;
  • the solution to these consequences;
  • lessons learned during the process;
  • and next steps.

Customers’ life experiences

Every customer journey narrative has six chapters:

  • plot background to frame the customer’s experiences;
  • the customer’s journey;
  • how the brand plays into that journey (if applicable);
  • how the customer’s experiences changed them;
  • what the customer learned from this journey;
  • and how other people can use this information to improve their lives.

Product and service insights

Narratives about product and service insights have seven chapters:

  • an overview of the product/service;
  • how that product/service affects users;
  • why the product/service is important to the brand’s mission or to users;
  • what about this product/service failed or succeeded;
  • why did that success or failure happen;
  • what lessons did this scenario create;
  • and how are the brand and its users moving forward.

You have the tools and knowledge necessary to be transparent, create vulnerable content, and succeed. And we need to tell vulnerable stories because sharing our experiences and embracing our common connections matters. So go ahead, put yourself out into the open, and see how your customers respond.

Usability Testing for Voice Content

It’s an important time to be in voice design. Many of us are turning to voice assistants in these times, whether for comfort, recreation, or staying informed. As the interest in interfaces driven by voice continues to reach new heights around the world, so too will users’ expectations and the best practices that guide their design.

Voice interfaces (also known as voice user interfaces or VUIs) have been reinventing how we approach, evaluate, and interact with user interfaces. The impact of conscious efforts to reduce close contact between people will continue to increase users’ expectations for the availability of a voice component on all devices, whether that entails a microphone icon indicating voice-enabled search or a full-fledged voice assistant waiting patiently in the wings for an invocation.

But voice interfaces present inherent challenges and surprises. In this relatively new realm of design, the intrinsic twists and turns in spoken language can make things difficult for even the most carefully considered voice interfaces. After all, spoken language is littered with fillers (in the linguistic sense of utterances like hmm and um), hesitations and pauses, and other interruptions and speech disfluencies that present puzzling problems for designers and implementers alike.

Once you’ve built a voice interface that introduces information or permits transactions in a rich way for spoken language users, the easy part is done. Nonetheless, voice interfaces also surface unique challenges when it comes to usability testing and robust evaluation of your end result. But there are advantages, too, especially when it comes to accessibility and cross-channel content strategy. The fact that voice-driven content lies on the opposite extreme of the spectrum from the traditional website confers it an additional benefit: it’s an effective way to analyze and stress-test just how channel-agnostic your content truly is.

The quandary of voice usability

Several years ago, I led a talented team at Acquia Labs to design and build a voice interface for Digital Services Georgia called Ask GeorgiaGov, which allowed citizens of the state of Georgia to access content about key civic tasks, like registering to vote, renewing a driver’s license, and filing complaints against businesses. Based on copy drawn directly from the frequently asked questions section of the Georgia.gov website, it was the first Amazon Alexa interface integrated with the Drupal content management system ever built for public consumption. Built by my former colleague Chris Hamper, it also offered a host of impressive features, like allowing users to request the phone number of individual government agencies for each query on a topic.

Designing and building web experiences for the public sector is a uniquely challenging endeavor due to requirements surrounding accessibility and frequent budgetary challenges. Out of necessity, governments need to be exacting and methodical not only in how they engage their citizens and spend money on projects but also how they incorporate new technologies into the mix. For most government entities, voice is a completely different world, with many potential pitfalls.

At the outset of the project, the Digital Services Georgia team, led by Nikhil Deshpande, expressed their most important need: a single content model across all their content irrespective of delivery channel, as they only had resources to maintain a single rendition of each content item. Despite this editorial challenge, Georgia saw Alexa as an exciting opportunity to open new doors to accessible solutions for citizens with disabilities. And finally, because there were relatively few examples of voice usability testing at the time, we knew we would have to learn on the fly and experiment to find the right solution.

Eventually, we discovered that all the traditional approaches to usability testing that we’d executed for other projects were ill-suited to the unique problems of voice usability. And this was only the beginning of our problems.

How voice interfaces improve accessibility outcomes

Any discussion of voice usability must consider some of the most experienced voice interface users: people who use assistive devices. After all, accessibility has long been a bastion of web experiences, but it has only recently become a focus of those implementing voice interfaces. In a world where refreshable Braille displays and screen readers prize the rendering of web-based content into synthesized speech above all, the voice interface seems like an anomaly. But in fact, the exciting potential of Amazon Alexa for disabled citizens represented one of the primary motivations for Georgia’s interest in making their content available through a voice assistant.

Questions surrounding accessibility with voice have surfaced in recent years due to the perceived user experience benefits that voice interfaces can offer over more established assistive devices. Because screen readers make no exceptions when they recite the contents of a page, they can occasionally present superfluous information and force the user to wait longer than they’re willing. In addition, with an effective content schema, it can often be the case that voice interfaces facilitate pointed interactions with content at a more granular level than the page itself.

Though it can be difficult to convince even the most forward-looking clients of accessibility’s value, Georgia has been not only a trailblazer but also a committed proponent of content accessibility beyond the web. The state was among the first jurisdictions to offer a text-to-speech (TTS) phone hotline that read web pages aloud. After all, state governments must serve all citizens equally—no ifs, ands, or buts. And while these are still early days, I can see voice assistants becoming new conduits, and perhaps more efficient channels, by which disabled users can access the content they need.

Managing content destined for discrete channels

Whereas voice can improve accessibility of content, it’s seldom the case that web and voice are the only channels through which we must expose information. For this reason, one piece of advice I often give to content strategists and architects at organizations interested in pursuing voice-driven content is to never think of voice content in isolation. Siloing it is the same misguided approach that has led to mobile applications and other discrete experiences delivering orphaned or outdated content to a user expecting that all content on the website should be up-to-date and accessible through other channels as well.

After all, we’ve trained ourselves for many years to think of content in the web-only context rather than across channels. Our closely held assumptions about links, file downloads, images, and other web-based marginalia and miscellany are all aspects of web content that translate poorly to the conversational context—and particularly the voice context. Increasingly, we all need to concern ourselves with an omnichannel content strategy that straddles all those channels in existence today and others that will doubtlessly surface over the horizon.

With the advantages of structured content in Drupal 7, Georgia.gov already had a content model amenable to interlocution in the form of frequently asked questions (FAQs). While question-and-answer formats are convenient for voice assistants because queries for content tend to come in the form of questions, the returned responses likewise need to be as voice-optimized as possible.

For Georgia.gov, the need to preserve a single rendition of all content across all channels led us to perform a conversational content audit, in which we read aloud all of the FAQ pages, putting ourselves in the shoes of a voice user, and identified key differences between how a user would interpret the written form and how they would parse the spoken form of that same content. After some discussion with the editorial team at Georgia, we opted to limit calls to action (e.g., “Read more”), links lacking clear context in surrounding text, and other situations confusing to voice users who cannot visualize the content they are listening to.

Here’s a table containing examples of how we converted certain text on FAQ pages to counterparts more appropriate for voice. Reading each sentence aloud, one by one, helped us identify cases where users might scratch their heads and say “Huh?” in a voice context.

In areas like content strategy and content governance, content audits have long been key to understanding the full picture of your content, but it doesn’t end there. Successful content audits can run the gamut from automated checks for orphaned content or overly wordy articles to more qualitative analyses of how content adheres to a specific brand voice or certain design standards. For a content strategy truly prepared for channels both here and still to come, a holistic understanding of how users will interact with your content in a variety of situations is a baseline requirement today.

Other conversational interfaces have it easier

Spoken language is inherently hard. Even the most gifted orators can have trouble with it. It’s littered with mistakes, starts and stops, interruptions, hesitations, and a vertiginous range of other uniquely human transgressions. The written word, because it’s committed instantly to a mostly permanent record, is tame, staid, and carefully considered in comparison.

When we talk about conversational interfaces, we need to draw a clear distinction between the range of user experiences that traffic in written language rather than spoken language. As we know from the relative solidity of written language and literature versus the comparative transience of spoken language and oral traditions, in many ways the two couldn’t be more different from one another. The implications for designers are significant because spoken language, from the user’s perspective, lacks a graphical equivalent to which those scratching their head can readily refer. We’re dealing with the spoken word and aural affordances, not pixels, written help text, or visual affordances.

Why written conversational interfaces are easier to evaluate

One of the privileges that chatbots and textbots enjoy over voice interfaces is the fact that by design, they can’t hide the previous steps users have taken. Any conversational interface user working in the written medium has access to their previous history of interactions, which can stretch back days, weeks, or months: the so-called backscroll. A flight passenger communicating with an airline through Facebook Messenger, for example, knows that they can merely scroll up in the chat history to confirm that they’ve already provided the company with their e-ticket number or frequent flyer account information.

This has outsize implications for information architecture and conversational wayfinding. Since chatbot users can consult their own written record, it’s much harder for things to go completely awry when they make a move they didn’t intend. Recollection is much more difficult when you have to remember what you said a few minutes ago off the top of your head rather than scrolling up to the information you provided a few hours or weeks ago. An effective chatbot interface may, for example, enable a user to jump back to a much earlier, specific place in a conversation’s history.An effective chatbot interface may, for example, enable a user to jump back to a much earlier, specific place in a conversation’s history. Voice interfaces that live perpetually in the moment have no such luxury.

Eye tracking only works for visual components

In many cases, those who work with chatbots and messaging bots (especially those leveraging text messages or other messaging services like Facebook Messenger, Slack, or WhatsApp) have the unique privilege of benefiting from a visual component. Some conversational interfaces now insert other elements into the conversational flow between a machine and a person, such as embedded conversational forms (like SPACE10’s Conversational Form) that allow users to enter rich input or select from a range of possible responses.

The success of eye tracking in more traditional usability testing scenarios highlights its appropriateness for visual interfaces such as websites, mobile applications, and others. However, from the standpoint of evaluating voice interfaces that are entirely aural, eye tracking serves only the limited (but still interesting from a research perspective) purpose of assessing where the test subject is looking while speaking with an invisible interlocutor—not whether they are able to use the interface successfully. Indeed, eye tracking is only a viable option for voice interfaces that have some visual component, like the Amazon Echo Show.

Think-aloud and concurrent probing interrupt the conversational flow

A well-worn approach for usability testing is think-aloud, which allows for users working with interfaces to present their frequently qualitative impressions of interfaces verbally while interacting with the user experience in question. Paired with eye tracking, think-aloud adds considerable dimension to a usability test for visual interfaces such as websites and web applications, as well as other visually or physically oriented devices.

Another is concurrent probing (CP). Probing involves the use of questions to gather insights about the interface from users, and Usability.gov describes two types: concurrent, in which the researcher asks questions during interactions, and retrospective, in which questions only come once the interaction is complete.

Conversational interfaces that utilize written language rather than spoken language can still be well-suited to think-aloud and concurrent probing approaches, especially for the components in the interface that require manual input, like conversational forms and other traditional UI elements interspersed throughout the conversation itself.

But for voice interfaces, think-aloud and concurrent probing are highly questionable approaches and can catalyze a variety of unintended consequences, including accidental invocations of trigger words (such as Alexa mishearing “selected” as “Alexa”) and introduction of bad data (such as speech transcription registering both the voice interface and test subject). After all, in a hypothetical think-aloud or CP test of a voice interface, the user would be responsible for conversing with the chatbot while simultaneously offering up their impressions to the evaluator overseeing the test.

Voice usability tests with retrospective probing

Retrospective probing (RP), a lesser-known approach for usability testing, is seldom seen in web usability testing due to its chief weakness: the fact that we have awful memories and rarely remember what occurred mere moments earlier with anything that approaches total accuracy. (This might explain why the backscroll has joined the pantheon of rigid recordkeeping currently occupied by cuneiform, the printing press, and other means of concretizing information.)

For users of voice assistants lacking scrollable chat histories, retrospective probing introduces the potential for subjects to include false recollections in their assessments or to misinterpret the conclusion of their conversations. That said, retrospective probing permits the participant to take some time to form their impressions of an interface rather than dole out incremental tidbits in a stream of consciousness, as would more likely occur in concurrent probing.

What makes voice usability tests unique

Voice usability tests have several unique characteristics that distinguish them from web usability tests or other conversational usability tests, but some of the same principles unify both visual interfaces and their aural counterparts. As always, “test early, test often” is a mantra that applies here, as the earlier you can begin testing, the more robust your results will be. Having an individual to administer a test and another to transcribe results or watch for signs of trouble is also an effective best practice in settings beyond just voice usability.

Interference from poor soundproofing or external disruptions can derail a voice usability test even before it begins. Many large organizations will have soundproof rooms or recording studios available for voice usability researchers. For the vast majority of others, a mostly silent room will suffice, though absolute silence is optimal. In addition, many subjects, even those well-versed in web usability tests, may be unaccustomed to voice usability tests in which long periods of silence are the norm to establish a baseline for data.

How we used retrospective probing to test Ask GeorgiaGov

For Ask GeorgiaGov, we used the retrospective probing approach almost exclusively to gather a range of insights about how our users were interacting with voice-driven content. We endeavored to evaluate interactions with the interface early and diachronically. In the process, we asked each of our subjects to complete two distinct tasks that would require them to traverse the entirety of the interface by asking questions (conducting a search), drilling down into further questions, and requesting the phone number for a related agency. Though this would be a significant ask of any user working with a visual interface, the unidirectional focus of voice interface flows, by contrast, reduced the likelihood of lengthy accidental detours.

Here are a couple of example scenarios:

You have a business license in Georgia, but you’re not sure if you have to register on an annual basis. Talk with Alexa to find out the information you need. At the end, ask for a phone number for more information.

You’ve just moved to Georgia and you know you need to transfer your driver’s license, but you’re not sure what to do. Talk with Alexa to find out the information you need. At the end, ask for a phone number for more information.

We also peppered users with questions after the test concluded to learn about their impressions through retrospective probing:

  • “On a scale of 1–5, based on the scenario, was the information you received helpful? Why or why not?”
  • “On a scale of 1–5, based on the scenario, was the content presented clear and easy to follow? Why or why not?”
  • “What’s the answer to the question that you were tasked with asking?”

Because state governments also routinely deal with citizen questions having to do with potentially traumatic issues such as divorce and sexual harassment, we also offered the choice for participants to opt out of certain categories of tasks.

While this testing procedure yielded compelling results that indicated our voice interface was performing at the level it needed to despite its experimental nature, we also ran into considerable challenges during the usability testing process. Restoring Amazon Alexa to its initial state and troubleshooting issues on the fly proved difficult during the initial stages of the implementation, when bugs were still common.

In the end, we found that many of the same lessons that apply to more storied examples of usability testing were also relevant to Ask GeorgiaGov: the importance of testing early and testing often, the need for faithful yet efficient transcription, and the surprising staying power of bugs when integrating disparate technologies. Despite Ask GeorgiaGov’s many similarities to other interface implementations in terms of technical debt and the role of usability testing, we were overjoyed to hear from real Georgians whose engagement with their state government could not be more different from before.

Conclusion

Many of us may be building interfaces for voice content to experiment with newfangled channels, or to build for disabled people and people newer to the web. Now, they are necessities for many others, especially as social distancing practices continue to take hold worldwide. Nonetheless, it’s crucial to keep in mind that voice should be only one component of a channel-agnostic strategy equipped for content ripped away from its usual contexts. Building usable voice-driven content experiences can teach us a great deal about how we should envisage our milieu of content and its future in the first place.

Gone are the days when we could write a page in HTML and call it a day; content now needs to be rendered through synthesized speech, augmented reality overlays, digital signage, and other environments where users will never even touch a personal computer. By focusing on structured content first and foremost with an eye toward moving past our web-based biases in developing our content for voice and others, we can better ensure the effectiveness of our content on any device and in any form factor.

Eight months after we finished building Ask GeorgiaGov in 2017, we conducted a retrospective to inspect the logs amassed over the past year. The results were striking. Vehicle registration, driver’s licenses, and the state sales tax comprised the most commonly searched topics. 79.2% of all interactions were successful, an achievement for one of the first content-driven Alexa skills in production, and 71.2% of all interactions led to the issuance of a phone number that users could call for further information.

But deep in the logs we implemented for the Georgia team’s convenience, we found a number of perplexing 404 Not Found errors related to a search term that kept being recorded over and over again as “Lawson’s.” After some digging and consulting the native Georgians in the room, we discovered that one of our dear users with a particularly strong drawl was repeatedly pronouncing “license” in her native dialect to no avail.

As this anecdote highlights, just as no user experience can be truly perfect for everyone, voice content is an environment where imperfections can highlight considerations we missed in developing cross-channel content. And just as we have much to learn when it comes to the new shapes content can take as it jumps off the screen and out the window, it seems our voice interfaces still have a ways to go before they take over the world too.
