Question

The Spiral model uses linear development concepts like those used in _________________, but repeats four phases through its life cycle: requirements gathering, design, build, and evaluation.

Answer 1

The Spiral model uses linear development concepts like sequential design processes. It repeats four phases through its life cycle: requirements gathering, design, build, and evaluation. The end design is often better than the initial design, but time and resources are required for each loop in the spiral.

Step-by-step explanation:

The Spiral model uses linear development concepts like those used in sequential design processes, but repeats four phases through its life cycle: requirements gathering, design, build, and evaluation. The advantage of using a spiral design process is that the end design is often much better than the initial design. However, the significant disadvantage of the spiral design process is that time and resources are required for each loop in the spiral.
