The Spiral Model is a software development model that combines the elements of both design and prototyping-in-stages. It was proposed by Barry Boehm in 1986 and is especially suited for large, complex, and high-risk projects. The Spiral Model provides a systematic and iterative approach to software development and focuses heavily on risk assessment. Unlike other linear models such as the Waterfall Model, the Spiral Model allows for incremental releases of the product or incremental refinement through each iteration. The Spiral Model consists of a series of cycles or spirals. Each spiral represents a phase in the software development process. These spirals include planning, risk analysis, engineering, and evaluation. Each loop in the spiral indicates a development phase and allows for refinement of the software with a focus on understanding and mitigating risks before they become critical issues. The Spiral Model has four main phases in each spiral: 1. Planning Phase: This phase involves understanding the system requirements, both functional and non-functional. Stakeholder needs are identified and documented. Planning is done for cost estimation, schedule, and resource allocation. 2. Risk Analysis Phase: This is the most important feature of the Spiral Model. During this phase, all possible risks (technical, management, operational, etc.) are identified and strategies are developed to mitigate them. Prototypes are often built to better understand and reduce technical risks. 3. Engineering Phase: Based on the planning and risk analysis, the actual _________ ____ ____ ________ ____ _____ __________ _____ ___.
