What is Spiral Model?

Phases In Spiral Model

When to use the Spiral Model?

1. When the project is large, complex, and critical. 2. When risk and costs evaluation is important.

Advantages of Spiral Model

1. Good for critical/complex projects. 2. Strong approval and documentation control.

Disadvantages of Spiral Model

1. Risk analysis requires highly specific expertise. 2. Risk analysis has to be done right.
