easy📝 Conceptual Q2 of 15
Software Engineering - SDLC Models
Which statement best describes how requirements are handled in the iterative and incremental model?
ARequirements are gathered completely before any development starts
BRequirements are ignored until the final iteration
CRequirements evolve and are refined through each iteration
DRequirements are fixed and cannot change once development begins
Step-by-Step Solution
Solution:
  1. Step 1: Recall requirement handling in iterative model

    Requirements are not fixed upfront but evolve as the project progresses.
  2. Step 2: Match options to this behavior

    Requirements evolve and are refined through each iteration correctly states that requirements evolve and get refined in each iteration.
  3. Final Answer:

    Requirements evolve and are refined through each iteration -> Option C
  4. Quick Check:

    Requirements handling = Evolving per iteration [OK]
Quick Trick: Requirements evolve with each iteration [OK]
Common Mistakes:
  • Assuming all requirements are fixed upfront
  • Ignoring requirement changes during development
