In Agile methodologies, requirements are typically expected to be:

• A. Fixed and unchanging throughout the project.
• B. Described in complete detail before development begins.
• C. Subject to change but managed with formal change control.
• D. Evolving and refined through iteration and feedback.

Answer: (D)

In Agile, requirements are treated as evolving and refined through iteration and feedback. Teams keep a lightweight product backlog of user stories or similar items and continuously groom and reprioritize it as learning occurs. Each short iteration or sprint delivers a working increment, and stakeholders review that progress, providing new insights that reshape what will be built next. This ongoing cycle means upfront, exhaustive detailing isn’t necessary; instead, you adapt requirements based on real feedback, market changes, and new understanding of user needs. While there is some planning, the process emphasizes responsiveness over sticking rigidly to an initial plan, with changes incorporated smoothly by re-prioritizing work. This approach keeps the product aligned with what users actually value as learning unfolds.
