The goal of each iteration is to produce a working product. Cross-functional teams work on iterations of a product over a period of time, and this work is organized into a backlog that is prioritized based on business or customer value. Instead of in-depth planning at the beginning of the project, Agile methodologies are open to changing requirements over time and encourages constant feedback from the end users.

This is done through application of iterative processes to evolve a system most suited to the given circumstances. In the Evolutionary Model, the development engineering effort is made first to establish correct and precise requirement definitions and system scope, as agreed by all the users across the organization. Generally the phases occur in the same order as in the waterfall model, but they may be conducted in several cycles. Iterative enhancement model: This model has the same phases as the waterfall model, but with some restrictions. The spiral model focuses on identifying and eliminating high-risk problems by careful process design.Ĥ. The spiral model is intended for large, expensive and complicated projects. It provides the potential for rapid development of incremental versions of the software. It is an evolutionary software process model combining the iterative nature of prototyping with the controlled and systematic aspects of a linear sequential model. Spiral model: The spiral model was originally proposed by "Boehm". The requirements can be communicated more clearly and completely.ģ. In the prototype model the requirements can be set earlier and the more reliable customer sees the results very quickly. 
The customer evaluates the prototype to refine the requirements. Prototype model: In the prototype model the initial requirements gathering is done.
When it is possible to produce a stable design.Ģ. One phase must be complete before moving onto the next phase. The main drawback of the waterfall model is the difficulty of accommodating change after the process is underway.
