A company wants to deliver a software product in phases, allowing user feedback after each phase. Which model best fits this requirement?
AIncremental model
BWaterfall model
CBig Bang model
DSpiral model without feedback
Step-by-Step Solution
Solution:
  1. Step 1: Understand phased delivery with feedback

    Incremental model delivers software in parts, allowing feedback after each phase.
  2. Step 2: Compare models

    Waterfall is sequential, Big Bang is unstructured, Spiral includes feedback but option says without feedback.
  3. Final Answer:

    Incremental model -> Option A
  4. Quick Check:

    Phased delivery with feedback = Incremental [OK]
Quick Trick: Incremental = phased delivery + feedback [OK]
Common Mistakes:
  • Confusing Waterfall with phased delivery
  • Choosing Big Bang for structured phases
  • Ignoring feedback in Spiral model
