What is Spiral Model?

This model follows a process in which the requirements all the phase activity is performed iteratively till all the requirements are met. This enables the product to be demonstrated at any point of time during the development cycle. It allows the progress to be tracked and the customer approvals to be obtained at regular intervals, thereby reducing the risk of finding major defects at a later point of time.The spiral model is favored for large, expensive, and complicated projects. This model allows for incremental releases of the product, or incremental refinement through each time around the spiral. This model also explicitly includes risk management within software development. Identifying major risks, both technical and managerial, and determining how to lessen the risk helps keep the software development process under control. Advantages Changing requirements can be accommodated. Allows for extensive use of prototypes Requirements can be captured more accurately. Users see
