Why do we need a software process model?

By developing the software incrementally, it is cheaper and easier to make changes in the software as it is being developed. Compared to the waterfall model, incremental development has three important benefits: The cost of accommodating changing customer requirements is reduced.

What is RAD model?

Definition: The Rapid Application Development (or RAD) model is based on prototyping and iterative model with no (or less) specific planning. In general, RAD approach to software development means putting lesser emphasis on planning tasks and more emphasis on development and coming up with a prototype.

Is Waterfall better than agile?

Agile looks best where there is a higher chance of frequent requirement changes. Waterfall is easy to manage and a sequential approach. Agile is very flexible and allows to make changes in any phase. In Agile, project requirements can change frequently.

What is Agile method in SDLC?

Agile SDLC methodology is based on collaborative decision making between requirements and solutions teams, and a cyclical, iterative progression of producing working software. Work is done in regularly iterated cycles, known as sprints, that usually last two to four weeks.
