What is Waterfall Model?
The waterfall model is a software development model used in the context of large, complex projects, typically in the field of information technology. It is characterized by a structured, sequential approach to project management and software development.
Difference between Waterfall Model and Spiral Model
The waterfall model and Spiral model are used in software development. Waterfall model is also known as the classical or linear model because it follows sequential stages while the spiral model does not follow the sequential stages it follows the evolutionary way. The amount of risk in the waterfall model is more as compared to the spiral model because the errors or risks are identified and refined after the completion of each stage.
