ITPEC IP October 2021 — Question 50 of 100
The waterfall model completes the activities of one development phase before proceeding to the next. Work flows sequentially through requirements, design, implementation, testing, and operation, with each phase producing inputs for the following phase.
Answer (a)
Why not others:
- rapid construction using tools and reusable parts describes RAD
- creating an early model for users to inspect describes prototyping
- repeatedly developing divided functions and incorporating feedback describes iterative or incremental development
Key rule: Waterfall is a phase-gated sequential model in which development advances after the current phase is completed.
