Software Engineering - SDLC Models
A project requires delivering a working product quickly and then adding features in phases. The team also wants to test each phase thoroughly before moving on. Which SDLC model fits best?
AIncremental model
BWaterfall model
CSpiral model
DAgile model
Step-by-Step Solution
Solution:
  1. Step 1: Understand project delivery needs

    Quick initial delivery plus phased feature addition with thorough testing suits incremental delivery.
  2. Step 2: Identify matching SDLC model

    The Incremental model delivers working parts early and tests each increment before continuing.
  3. Final Answer:

    Incremental model -> Option A
  4. Quick Check:

    Phased delivery + testing = Incremental model [OK]
Quick Trick: Incremental delivers fast, tests each phase [OK]
Common Mistakes:
  • Choosing Agile without phased delivery
  • Assuming Waterfall delivers early
  • Confusing Spiral with incremental delivery
