An important task performed during the project planning stage is the selection of a suitable development model. We are developing E - परीक्षा web-site which is based on Spiral Model, because it offers a means of making the development process more visible. Because of the cascade from one phase to another, this model is known as Spiral Model. It is also known as System Life Cycle. The Spiral Model: Spiral model is a combination of iterative development process model and sequential linear development model i.e. waterfall model with very high emphasis on risk analysis. It allows for incremental releases of the product, or incremental refinement through each iteration around the spiral. The spiral model has four phases. A software project repeatedly passes through these phases in iterations called “Spirals”. 1) IDENTIFICATION 2) DESIGN 3) CONSTRUCTOR BUILD 4) EVALUATION AND RISK ANALYSIS 1) IDENTIFICATION : This phase starts with gathering the business requirements in the baseline spiral. In the subsequent spirals as the product matures, identification of system requirements, subsystem requirements and unit requirements are all done in this phase. This also includes understanding the system requirements by continuous communication between the customer and the system
