GSLC · Question #135
Which model is a software development process combining elements of both design and prototyping-in-stages, in an effort to combine advantages of top-down and bottom-up concepts?
The correct answer is A. Spiral. The Spiral model, developed by Barry Boehm, is an iterative software development process that combines the structured, top-down planning of the Waterfall model with the iterative, bottom-up nature of Prototyping.

Explanation
The Spiral model, developed by Barry Boehm, is an iterative software development process that combines the structured, top-down planning of the Waterfall model with the iterative, bottom-up nature of Prototyping. Each 'spiral' cycle passes through planning, risk analysis, engineering, and evaluation phases, making it particularly suited for large, complex, or high-risk projects. The Waterfall model is strictly sequential (top-down only). The Prototyping model focuses on building working models but lacks structured risk management. 'View' is not a recognized SDLC model.
