Question

Which is true of The Waterfall lifecycle model: 1) A partially complete system can demonstrate key elements 2) A series of deliverables produced during different phases 3) Uses Risk Analysis and incremental delivery process 4) Emphasizes interactions instead of process 5) All of the above 6) None of the above

Answer 1

The correct option is #2 - "a series of deliverables produced during different phases." The waterfall model is a linear sequential approach where the development progresses through a series of phases, each preceding phase must be completed before the next phase can begin. Each phase produces deliverables, which are then used as inputs for the next phase. It is a document-driven approach, where requirements, design, implementation, testing, and maintenance are each treated as separate stages. Options 1, 3, 4, 5, and 6 do not accurately describe the waterfall model.
