Which software development model is actually a meta-model that incorporates a number of the softwaredevelopment models?
A.
The Waterfall model
B.
The modified Waterfall model
C.
The Spiral model
D.
The Critical Path Model (CPM)
Explanation:
The spiral model is a risk-driven process model generator for software projects. Thus, the incremental,
waterfall, prototyping, and other process models are special cases of the spiral model that fit the risk patterns of
certain projects.
Incorrect Answers:
A: The Waterfall model is a special case of the Spiral model, not the opposite way around.
B: The modified Waterfall model is a special case of the Spiral model, not the opposite way around.
D: A critical path model is not a meta-model. The critical path model requires you to establish the time frame for
a project and schedule start and end times for each task in the project.https://en.wikipedia.org/wiki/Spiral_model
