Rare and complex NATO tank spotted and destroyed in Russia's Kursk region

A "rare and complex" British Challenger 2 tank that Ukraine received from the UK was spotted in the Kursk region of Russia. "The destruction of a heavy British Challenger 2 tank, a rather rare and complex tank to operate, by the marines of our 155th brigade indicates the concentration of enemy efforts," Two Majors Telegram channel said. The fact that such rare military hardware was transferred to the Russian region indicates the intention of the Armed Forces of Ukraine to use all opportunities to hold positions in the Kursk region, authors of the channel added.

Design goals and Complexity

Programmers solve problems. How they solve each problem is a function of their skill, talent, knowledge & time. The resultant solution will resolve the problem with greater or lesser complexity in the design. Thus, I find thinking about how (and more importantly where) complexity is handled, a useful way to evaluate a design. For this I use the time-honored technique of having three levels:

Level Zero

(Below this level, the problem is not solved)

The programmer has provided a solution. However, the interface is a mine-field; click things in the wrong order, the program crashes. Or it works great, but you need to reread the documentation Every. Single. Time. Or the resultant surrounding workflow is a Rube Goldberg device. However it surfaces, the programmer has placed the complexity on the user.

Level One

The interface is well thought out and reasonably intuitive. Controls work as expected and the solution is robust - even bulletproof. The solution not only fits the larger context, it improves it. The code itself however, is hard to change (or even understand). It is not well-organized; Or is, but full of tricky, interleaved logic. Or over-engineered, over-patterned etc. Here, the programmer has placed the complexity on the maintainer.[1]

Level Two

The burden of managing complexity is on the current programmer. The person writing the code takes the time and employs the talent and skill necessary to find an elegant solution that reduces the code to the minimum complexity needed to solve the problem and does so in such a way that is understandable (and changeable) later: The user gains the benefits of a level 1 design, while maintainers are left with clean code to change.[2]

Implications

Level zero code is common; it's the default for new programmers and an uncomfortable amount of commercial software. The thing of it is: Too often this sort of code is derided (including by me) when there is both a de facto and a cost-benefit rationale for managing complexity this way. Short-term projects are one example; software written for one's own use is another.

Level 1 software can be very valuable and enduring. I tend to equate this type of code with the Hacker ethic in all senses of that term. And I don't mean that pejoratively - we all use hacked together solutions every day and much of the world's technology infrastructure is built on it. It is a practical and stable design level.

Having the skill (and the time) to write level 2 code is a rare and wonderful thing. Amidst the hyperbole, aspiring to be such a programmer is at the heart of the "Software as Craft" movement and is a worthwhile goal for anyone who aspires to be a professional programmer.

I don't believe level 2 is inherently better than a level 1 (or level zero!) - it's about context - however, I think that for regularly edited and changed code (i.e. much IT software), this level of skill is what's implicitly expected (if not gotten) by the customer. Ironically, the time needed is often the first thing that goes as a non-technical customer can only assess code quality based on level 1 considerations and so pushes for faster results because everything "looks" OK. Only later - when their investment can't be changed without major overhaul - do they realize there is something wrong. And so the cycle continues...

Summary

This model is handy in several situations including: Judging the quality of an actual solution; choosing among different solutions to a given problem; estimating - and even when to stop refactoring. And while I don't believe that all code should be worked until it exhibits level 2 quality, it is what I want others to think of the code I leave behind. And it is what I hope to encounter in theirs. That said, being a successful professional programmer requires (among many other things) the ability to write all three levels of code, and the judgment to know when each is appropriate to use.


[1] This may well be the same person who wrote the code. The essential characteristic of a level 1 design is that complexity is put off to future efforts, not the current one. Thus level 1 designs tend to be high in technical debt.

[2]How the programmer achieves this is a matter of personal preference and technique. I do not subscribe to the notion that any particular set of programming practices provides this - or inhibit it by their absence. It has always been the people, not their practices that is the essential determinant of quality. Anyone who says different, is selling something.

Recognizing and Managing Complexity: Teaching Advanced Programming Concepts and Techniques Using the Zebra Puzzle

Teaching advanced programming can be a challenge, especially when the students are pursuing different majors with diverse analytical and problem-solving capabilities. The purpose of this paper is to explore the efficacy of using a particular problem as a vehicle for imparting a broad set of programming concepts and problem-solving techniques. We present a classic brain teaser that is used to communicate and demonstrate advanced software development concepts and techniques. Our results show that students with varied academic experiences and goals, assuming at least one procedural/structured programming pre-requisite, can benefit from and also be challenged by such an exercise. Although this problem has been used by others in the classroom, we believe that our use of this problem in imparting such a broad range of topics to a diverse student population is unique.

Multiplication complexity in education activities with fair use principle of copyright in Indonesia

Copying and duplicating papers for educational purposes is a violation form of copyright in Indonesia. The principle of fair use in education is a form of structured violation. Copying and duplicating the papers of the authors for educational purposes has provided commercial (business) benefits for libraries and universities. The research method is conducted using the observation method in libraries and universities that duplicate papers. The method also uses the normative juridical method that connects duplication of the papers in libraries and universities with the fair use principle. The results explain the authors' loss from copying and duplicating of papers in libraries and universities. Therefore, copying and duplicating the papers can only be done by implementing the responsibility system. Copying and duplicating the papers of the authors' in libraries and universities can be allowed if they fulfil the elements of copyright protection in the new concept.

Case Study of a Complex Informing System: Joint Interagency Field Experimentation (JIFX)

The Joint Interagency Field Experimentation (JIFX) event, organized by the Naval Postgraduate School (NPS), is conducted 3-4 times a year at various locations. The four day event can be characterized as an informing system specifically designed to facilitate structured and unstructured communications between a variety of parties—e.g., software developers, inventors, military and civilian users of various technologies, academics, and agencies responsible for identifying and procuring technology solutions—that frequently are constrained in their informing activities in more restrictive venues. Over the course of the event, participants may observe technology demonstrations, obtain feedback from potential users, acquire new ideas about their technologies might be employed and, perhaps most significantly, engage in ad hoc collaborations with other participants. The present paper describes an exploratory case research study that was conducted over a one year period and involved both direct observation of the event and follow-up interviews with 49 past participants in the event. The goal of the research was to assess the nature of participant-impact resulting from attending JIFX and to consider the consistency of the findings with the predictions of various theoretical frameworks used in informing science. The results suggest that participants perceived that the event provided significant value from three principal sources: discovery, interaction with potential clients (users) of the technologies involved, and networking with other participants. These findings were largely consistent with what could be expected from informing under conditions of high complexity; because value generally derives from combinations of attributes rather than from the sum of individual attributes, we would expect that overall value from informing activities will be perceived even though estimates of the incremental value of that informing cannot be made.

Fitness, Extrinsic Complexity and Informing Science

Aim/Purpose We establish a conceptually rigorous definition for the widely used but loosely defined term “fitness”. We then tie this definition to complexity, highlighting a number of important implications for the informing science transdiscipline. Background As informing science increasingly incorporates concepts of fitness and complexity in its research stream, rigorous discussion and definition of both terms is essential to effective communication. Methodology Our analysis consists principally of a synthesis of past work in the informing science field that incorporates concepts from evolutionary biology, economics and management. Contribution We provide a rigorous approach to defining fitness and introduce the construct “extrinsic complexity”, as a measure of the amount of information required to predict fitness, to more fully differentiate this form of complexity from other complexity constructs. We draw a number of conclusions regarding how behaviors under low and high extrinsic complexity will differ. Findings High extrinsic complexity environments are likely to produce behaviors that include resistance to change, imitation, turbulence and inequality. Recommendations for Practitioners As extrinsic complexity grows, effective search for problem solutions will increasingly dominate employing recommended solutions of “best practices”. Recommendation for Researchers As extrinsic complexity grows, research tools that rely on decomposing individual effects and hypothesis testing become increasingly unreliable. Impact on Society We raise concerns about society’s continuing investment in academic research that discounts the extrinsic complexity of the domains under study. Future Research We highlight a need for research to operationalize the concepts of fitness and complexity in practice.

Complexity Leadership Theory and the Leaders of Transdisciplinary Science

Aim/Purpose: Given that leadership has been shown to play a key role in knowledge-producing organizations, leaders of transdisciplinary science have received surprisingly little empirical attention. This study addresses the research gap by examining leadership in the context of a new transdisciplinary research organization. Background: Drawing on complexity leadership theory—a framework developed for identifying behaviors that facilitate creativity, learning, and adaptability in complex adaptive systems—this study examines leadership roles and practices that affect the generation of adaptive dynamics in transdisciplinary science. Methodology: The study is based on a longitudinal, qualitative in-depth case study on a newly formed transdisciplinary research center and its leadership team. The data includes ethnographic observations from leadership meetings and interviews with leaders. Contribution: This unique empirical case contributes to the study of transdisciplinary science by shedding light on the actions of academic leaders as they try to support transdisciplinary conversation, learning, and collaboration in a new center. Findings: The analysis shows that the leaders relied on both enabling and administrative leadership practices in a way that made them the focal point of transdisciplinary knowledge integration and thus jeopardized the creation of adaptive dynamics throughout the organization. Recommendations for Practitioners: The study highlights the importance of having knowledge brokers and hybrid scholars in strategic positions at different levels of the transdisciplinary research organization already in its early stages. Recommendation for Researchers: Longitudinal qualitative case studies that rely on different types of data provide rich information on how new leadership conceptualizations are implemented in organizations and the complex ways in which they relate to knowledge creation processes and outcomes. Impact on Society: Transdisciplinary science has the potential to find cures to complex diseases. Understanding leadership in transdisciplinary science can help in maintaining transdisciplinary research activities in the long run and thus make it more impactful. Future Research: The use of leadership roles and practices will be examined at different developmental stages in the transdisciplinary research process.

Transdisciplinary Knowledge Producing Teams: Toward a Complex Systems Perspective

Aim/Purpose: Transdisciplinarity is considered as a framework for understanding knowledge producing teams (KPTs). Features of transdisciplinary knowledge producing teams (TDKPTs) are provided using a complex adaptive systems (CAS) lens. TDKPT features are defined and linked to complexity theory to show how team participants might develop skills that more truly express complex adaptive conditions. Background: TDKPTs are groups of stakeholder participants tasked with producing knowledge across disciplinary, sectoral, and ecological boundaries. TDKPTs reflect components of complex adaptive systems (CAS) and exemplify how CAS behave and function. Methodology: The paper accesses literature from the Science-of-Team-Science (SciTS), complexity theory, and systems theory to construct a typology of the features of TDKPTs. Contribution: This paper provides a list of features developed from a diverse body of literature useful for considering complexity within TDKPTs. Findings: The paper proposes a series of features of transdisciplinary knowledge producing teams. In addition, the authors identify important skill building aspects needed for TDKPTs to be successful. Recommendations for Practitioners: The paper provides a framework by which team functioning can be considered and enhanced within TDKPTs. Recommendation for Researchers: The paper suggests categorical features of transdisciplinary teams for research on the collaborative processes and outcomes of TD teams. Future Research: Knowledge producing team members need to engage in theoretical, episte-mological, and methodological reflections to elucidate the dynamic nature of TD knowledge producing teams. Understanding how conflict, dissonance, and reciprocal interdependencies contribute to knowledge generation are key areas of future research and inquiry.

Aim/Purpose: As traditional Knowledge Management (KM) struggles to support the personal needs of knowledge workers in a new era of accelerating information abundance, we examine the shortcomings and put forward alternative scenarios and architectures for developing a novel Personal KM System (PKMS). Background: While prior publications focused on the complementing features compared to conventional dynamic KM models, our emphasis shifts to instantiating a flourishing PKMS community supported by a Digital Platform Ecosystem. Methodology: Design science research focusing on conceptual analysis and prototyping. Contribution: The PKMS concept advances the understanding of how digital platform communities may serve members with highly diverse skills and ambitions better to gainfully utilize the platform’s resources and generative potential in their personal and local settings. Findings: We demonstrate how the needs to tackle attention-consuming rising entropy and to benefit from generative innovation potentials can be addressed. Future Research: As this article has iteratively co-evolved with the preparing of a PKMS implementation, business, and roll-out plan, the prototype’s testing, completion, and subsequent migration to a viable system is of primary concern.

Facilitating Scientific Events Guided by Complex Thinking: A Case Study of an Online Inter/Transdisciplinary Advanced Training School

Aim/Purpose This paper aims to illustrate, through an exploratory ideographic case study, how a Complex Thinking framework can inform the design of scientific events and the facilitation of scientific Inter and Transdisciplinary groups towards positive emergent outcomes, both at the level of the functioning of the group and the collective complexity of their thinking. Moreover, it aims to show how the choice of facilitation strategies can contribute to positive emergent outcomes in the context of a fully online event, with its inherent constraints. Finally, this study aims to conduct an exploratory qualitative evaluation of the participants’ experiences during School, with a focus on the processes and how they relate to the aims of the School and the goals of the facilitation. Background Science needs to embrace modes of knowing capable of generating more complex (differentiated, integrated, recursively organized, emergent), ecologically fit, and creative responses, to meet the complexity of the world’s challenges. New formats and strategies are required that attend to the facilitation of Inter and Transdisciplinary scientific events and meetings, towards creative and complex outcomes. A Complex Thinking framework provides suggestions for the facilitation of Inter and Transdisciplinary meetings and events through targeting key properties which may lead to the emergence of complex and creative outcomes. Methodology We adopt an ideographic case study approach to illustrate how a complex systems approach, in particular a Complex Thinking framework, grounded in an enactive view of cognition, guided the design choices and the facilitation strategies of an online Inter and Transdisciplinary Advanced Training School (Winter School). We aim to illustrate how the facilitation strategies were selected and used to promote deep and creative interactions within the constraints of an online environment. We adopt an exploratory qualitative approach to investigate the participants’ reports of their experiences of the School, in light of the principles and goals that guided its design and facilitation. Contribution This paper opens a new area of theoretical and applied research, under the scope of a Complex Thinking framework, focused on the facilitation of Inter and Transdisciplinarity at scientific events, meetings, and discussions towards complex and creative outcomes. Findings The results of the exploratory qualitative analysis of the participants’ experiences regarding the event suggest a critical role of its methodology in fostering rich, deep, and constructive interactions, in leading to the emergence of a collective group experience, to the integration of ideas, and in facilitating transformative personal experiences, under the effects of the emergent group processes. It suggests that the strategies employed were successful, anticipating and overcoming the particular constraints of an online event. Recommendations for Practitioners This case study suggests that a Complex Thinking framework can fruitfully guide the design of facilitation strategies and activities for scientific events and meetings, activating a number of key relational processes that contribute to or boost the emergence of positive group experiences and the production and integration of novel ideas. Recommendations for Researchers This study calls for action-oriented and applied research focused on the developmental evaluation of innovations, regarding the facilitation of scientific creativity and integration, within the scope of a Complex Thinking approach. Impact on Society This paper calls for new modes of organization and formats of scientific activities, suggesting that Inter and Transdisciplinary events and meetings may benefit from intentional management and facilitation of interactions between participants to produce transformative impacts. It demonstrates the importance of the organizational principles used to plan and run events that engage multiple and various societal agents, from academics to practitioners and social activists, towards enhancing their richness and relevance to complex real-world challenges. Future Research This study highlights the need for process-focused systematic case study research using complex systems-informed designs to explore how and which facilitation strategies may promote which (interaction of) properties of Complex Thinking and associated processes and how, and under which conditions, these lead to more complex and creative outcomes.

The Three Worlds of Task Complexity

Aim/Purpose: To provide a systematic approach to defining task complexity using a three worlds model previously introduced in informing science research. Background: The task complexity construct presents researchers with a quandary. While it appears useful on the surface, repeated attempts to define it rigorously have failed to gain traction in the broader research community. The level of inconsistency between definitions is shown to have changed little in the past 20 years. Methodology: Using a common framework that treats task complexity as a latent construct residing between sources and outcomes, moderated by both task familiarity and task discretion, separate models for each of the three worlds are developed. Contribution: Our paper proposes a potential path forward by showing how many issues in past task complexity research can be reconciled by framing the construct according to the three worlds model: the world we experience, the world of human artifacts, and the “real world.” Findings: The framework defines experienced complexity as occurring in the mind of the task performer while performing a single task instance, intrinsic complexity as a function of the internal characteristics of the problem space used to perform a bounded set of task instances, and extrinsic complexity as the ruggedness of the fitness landscape in which the task is performed. Recommendation for Researchers: It offers a path to convergence for definitions of task complexity. Future Research: The three worlds of task complexity can potentially be applied to many practical problems.

Information Technology and the Complexity Cycle

Aim/Purpose: In this paper we propose a framework identifying many of the unintended consequences of information technology and posit that the increased complexity brought about by IT is a proximate cause for these negative effects. Background: Builds upon the three-world model that has been evolving within the informing science transdiscipline. Methodology: We separate complexity into three categories: experienced complexity, intrinsic complexity, and extrinsic complexity. With the complexity cycle in mind, we consider how increasing complexity of all three forms can lead to unintended consequences at the individual, task and system levels. Examples of these consequences are discussed at the individual level (e.g., deskilling, barriers to advancement), the task level (e.g., perpetuation of past practices), as well as broader consequences that may result from the need to function in an environment that is more extrinsically complex (e.g., erosion of predictable causality, shortened time horizons, inequality, tribalism). We conclude by reflecting on the implications of attempting to manage or limit increases of complexity. Contribution: Shows how many unintended consequences of IT could be attributed to growing complexity. Findings: We find that these three forms of complexity feed into one another resulting in a positive feedback loop that we term the Complexity Cycle. As examples, we analyze ChatGPT, blockchain and quantum computing, through the lens of the complexity cycle, speculating how experienced complexity can lead to greater intrinsic complexity in task performance through the incorporation of IT which, in turn, increases the extrinsic complexity of the economic/technological environment. Recommendations for Practitioners: Consider treating increasing task complexity as an externality that should be considered as new systems are developed and deployed. Recommendation for Researchers: Provides opportunities for empirical investigation of the proposed model. Impact on Society: Systemic risks of complexity are proposed along with some proposals regarding how they might be addressed. Future Research: Empirical investigation of the proposed model and the degree to which cognitive changes created by the proposed complexity cycle are necessarily problematic.

PROBLEMATIZING FIT AND SURVIVAL: TRANSFORMING THE LAW OF REQUISITE VARIETY THROUGH COMPLEXITY MISALIGNMENT

The law of requisite variety is widely employed in management theorizing, and is linked with core strategy themes such as contingency and fit. We reflect upon requisite variety as an archetypal borrowed concept. We contrast its premises with insights from institutional and commitment literatures, draw propositions that set boundaries to its applicability, and review the ramifications of what we term "complexity misalignment." In this way, we contradict foundational assumptions of the law, problematize adaptation- and survival-centric views of strategizing, and theorize the role of human agency in variously complex regimes.
