SDLC Methodology:

This document play a vital role in the development of life cycle (SDLC) as it describes the complete requirement of the system.  It means for use by developers and will be the basic during testing phase.  Any changes made to the requirements in the future will have to go through formal change approval process.

SPIRAL MODEL was defined by Barry Boehm in his 1988 article, “A spiral Model of Software Development and Enhancement.  This model was not the first model to discuss iterative development, but it was the first model to explain why the iteration models.

As originally envisioned, the iterations were typically 6 months to 2 years long.  Each phase starts with a design goal and ends with a client reviewing the progress thus far.   Analysis and engineering efforts are applied at each phase of the project, with an eye toward the end goal of the project.

The steps for Spiral Model can be generalized as follows:

  1. Evaluating the first prototype in terms of its strengths, weakness, and risks.
  2. Defining the requirements of the second prototype.
  3. Planning an designing the second prototype.
  4. Constructing and testing the second prototype.

The following diagram shows how a spiral model acts like:
