Describe the stages of spiral model. Distinguish it from the incremental model of software development.
There are six phases in the "Spiral Model" which are:
1.The customer communication task – to establish effective communication between developer and customer.
2.The planning task – to define resources, time lines and other project related information..
3.The risk analysis task – to assess both technical and management risks.
4.The engineering task – to build one or more representations of the application.
5.The construction and release task – to construct, test, install and provide user support (e.g., documentation and training).
6.The customer evaluation task – to obtain customer feedback based on the evaluation of the software representation created during the engineering stage and implemented during the install stage.
7.Incremental model generates working software quickly and early during the software life cycle as compare to spiral model.
8.It is more flexible - less costly to change scope and requirements.
