Spiral Model

Spiral Model

Developed by Barry Boehm in 1988. it provides the potential for rapid development of incremental versions of the software. In the spiral model, software is developed in a series of incremental releases.  During early iterations , the incremental release might be a paper model or prototype.

        Each iteration consists of

Planning, Risk Analysis, Engineering, Construction & Release & Customer Evaluation.

Customer Communication: Tasks required to establish effective communication between developer and customer.

Planning: Tasks required to define resources, timelines, and other project related information.

Risk Analysis: Tasks required to assess both technical and management risks.

Engineering: Tasks required to build one or more representatives of the application.

Construction & Release: Tasks required to construct, test, install and provide user support (e.g., documentation and training)

Customer evaluation: Tasks required to obtain customer feedback based on evaluation of the software representations created during the engineering stage and implemented during the installation state.
