ITPEC FE Morning April 2022 Question 50
ITPEC FE Morning April 2022 — Question 50 of 80
Spiral Model — iterative development model that repeats cycles from requirements to implementation.
The spiral model repeats development phases (requirements → design → implementation → testing) in multiple iterations, refining the product each cycle.
Why not others:
- (a) Prototyping model — builds a quick prototype to clarify requirements, not a full repeated cycle
- (b) Relational model — a database model, not a software development model
- (d) Waterfall model — linear, single-pass process with no repetition of phases
Key rule: "Repeats from requirements to implementation" = iterative = Spiral model.
