Detailed explanation-1: -Two software process models are waterfall and spiral model. The difference between waterfall and spiral model is that waterfall model is used for smaller projects and projects with clear requirements while the spiral model is used for large, complex projects that require continuous risk analyzing.
Detailed explanation-2: -The main difference is that Waterfall is a linear system of working that requires the team to complete each project phase before moving on to the next one while Agile encourages the team to work simultaneously on different phases of the project.
Detailed explanation-3: -The spiral model enables gradual releases and refinement of a product through each phase of the spiral as well as the ability to build prototypes at each phase. The most important feature of the model is its ability to manage unknown risks after the project has commenced; creating a prototype makes this feasible.
Detailed explanation-4: -Conclusion. The waterfall is still effective for certain projects that are set within a constrained timeline or budget.
