The software development process starts with gathering business requirements, defining system, subsystem and unit requirements, and understanding customer feedback. In subsequent spirals, a working version of the product is developed and sent to the client for review. The product is then deployed to its identified market. The design phase of the software project involves conceptual and architectural design in the baseline spiral, logical design of modules, and physical product design. The final design is based on customer feedback.
Spiral Model is the best software engineering method because it provides multiple loops to ensure that a software project achieves its goals. There are many stages of the model, with each stage representing a task region. From the initial requirements gathering phase to the final client review phase, the software development process has several stages. Each task region has a goal and a defined set of requirements. As the software development process proceeds, it is important to ensure effective communication between the client and the software developer, define project-related information, and assess risks.
The Spiral model also helps create multiple versions of a software product. It is often preferred by companies because it facilitates iterative development, allowing them to release one version of a product and begin work on a new version based on feedback. The model is compatible with multiple software builds, and it forces users to be involved throughout the entire process. This method is also characterized by strict control, and requires the use of a domain of change for a successful product development.
