Episode 114: Christof Ebert on Requirements Engineering

In this episode we talk to Christof Ebert about requirements engineering. As the name "engineering" suggests, we need to be systematic when working and managing requirements. Christof will structure RE into several activities, namely elicitation (identifying the relevant requirements), specification (clearly describing requirements), analysis (synthesizing a solution), verification and validation (achieving good requirements quality), comittment (allocating requirements to a project, product release or iteration), and management (keeping track of the implementation status of requirements). In this episode we discuss these activities and highlight lots of practical guidance.
