Comparison of different Models

Comparison between Waterfall model and Spiral model

Waterfall model works in sequential method whereas Spiral model works in evolutionary method.

Waterfall model errors or risks are identified and rectified after the completion of stages whereas Spiral model errors or risks are identified and rectified earlier.

Waterfall model is applicable for small project whereas Spiral model is used for large project.

Flexibility to change in waterfall model is difficult whereas flexibility to change in spiral model is not difficult.

There is high amount risk in waterfall model whereas there is low amount risk in spiral model.
