What is the Spiral methodology and where is it best applied?

The Spiral methodology combines elements of Waterfall and Agile, with a strong emphasis on risk management. The project is divided into multiple cycles, and each cycle includes:

1. Determining objectives

2. Identifying and resolving risks

3. Development and testing

4. Planning the next iteration

At the end of each cycle, a prototype is reviewed before moving forward.

Best suited for:

• Large-scale, complex systems

• Projects with high technical or business risk

Without proper risk assessment, Spiral projects can become expensive and difficult to manage.
