Step-by-step explanation:
Agile method is an approach that is intended to facilitate the development of systems that must change rapidly in response to dynamic business environments. It is a continuous development view that focuses on gradually improving on existing skills. Agile method follows a spiral design process where changes are made in the design, and then the improved design is evaluated. The advantage of using agile method is that the end design is often much better than the initial design.
