The spiral model was introduced, due to the shortcomings in the waterfall and prototype models of software engineering. It is a combination of the said two models of software development. From the name of the model, it can be derived that the activities of software development are carried out like a spiral. To explain the model further, the entire software development process is broken down into small projects. The phases of the spiral model are as follows:
Planning Phase
Risk Analysis Phase
Engineering Phase
Coding and Implementation Phase
Evaluation Phase
The waterfall model is often also referred to as the linear and sequential model, for the flow of activities in this model are rather linear and sequential as the name suggests. In this model, the software development activities move to the next phase only after the activities in the current phase are over. However, like is the case with a waterfall, one cannot return to the previous stage. The phases of this model are:
Requirement Gathering and Analysis Phase
Design Phase
Coding Phase
System Integration Phase
Testing and Debugging Phase
Delivery Phase
Maintenance Phase
Planning Phase
Risk Analysis Phase
Engineering Phase
Coding and Implementation Phase
