A software plan repeatedly passes through these phases in repetitions called Spirals.
Each spiral can be termed as a loop and each loop is a separate development process in a spiral model. This blog will discuss this prodigious and widely used SDL model in detail. Each iteration also known as a phase has four stages. It is a combination of both Prototype development process and Linear development process (waterfall model). This model place more emphasis on risk analysis. Learn about the benefits of the spiral model and its various phases. Spiral Model Phases: Activities performed during phase: Planning: It includes estimating the cost, schedule and resources for the iteration.
Spiral Model: Spiral Model was first described by Barry W. Boehm (American Software Engineer) in 1986. Spiral model works in an iterative nature. The spiral model is similar to the incremental model, with more emphasis placed on risk analysis.The spiral model has four phases: Planning, Risk Analysis, Engineering and Evaluation. The four activities (Planning, Risk analysis, engineering and evaluation) form the intermediary phases of a spiral model and is repeated again for each loop. SDLC Spiral Model - The spiral model is another important SDLC model that came into use when the iteration in product development came into the applied concept. The spiral model carries out development in loops. The features of this model is a emerges from the combination of waterfall model and prototype model. Spiral Lifecycle Model was initiated by Boehm and is meant to be used while working with high risk projects.
It also involves understanding the system requirements for continuous communication between the system analyst and the customer
Spiral model was first introduced by Barry Boehm in 1986 and since then it has been one of the most preferred SDLC models for long-term and high-risk projects. As the name suggests, all the activities is executed in the …
How does Spiral Model work? Software Development Model plays a significant role in the success of any project. A software project repeatedly passes through these phases in iterations (called Spirals in this model).
