    - Spiral model is a risk driven process model that bases on the unique risk patterns of a given project.

    - It is similar to incremental model and waterfall model with very high emphasis on risk analysis.

    - Only this model has the risk analysis. Risk analysis is involved in every cycle of development.

    - If any risk is found during the risk analysis then alternate solutions are suggested and implemented.

    - While using the spiral model the process is complex, if there is any issues or any change we need to iterate the whole life cycle.
