A hospital in Chennai wants to develop a patient portal, but its requirements are unclear and expected to change as clinicians see working versions. Which SDLC model best suits this situation?

An iterative or Agile model suits best. Because requirements are unclear and will change after clinicians see working versions, short cycles with repeated feedback accommodate change, whereas Waterfall and V-model assume stable requirements fixed upfront.

  1. AWaterfall model, because each phase is completed once in strict sequence
  2. BIterative or Agile model, with working increments reviewed repeatedlyCorrect
  3. CBig-bang deployment with no feedback
  4. DRigid V-model with frozen requirements

Explanation

Unclear and evolving requirements call for iterative or Agile development, where increments are delivered and feedback is folded into the next cycle. Waterfall and V-model assume stable, frozen requirements, so changes late in the project are costly. Big-bang with no feedback ignores the need to refine.
