The core objective of the V life cycle model is to illustrate the importance of the relationship between development and testing tasks. 35 RNB Global University, Bikaner. Course Code - 13004500

The V Life Cycle Model To accommodate this reality, Mathur and Malik (2010) proposed an expanded version of the V-Model, called the advanced V-Model, that incorporates both testing and maintenance activities into the life cycle. Since the V-Model addresses its errors shortly after they are identified, it becomes less expensive to resolve them, which is perhaps the greatest advantage of using this model, specifically when compared to the classic waterfall model. 36 RNB Global University, Bikaner.

The V Life Cycle Model the fact that tests are performed since the beginning of the process only increases its efficiency. On the other hand, and much like the waterfall model, this model is very rigid and there is little room for flexible adaptation, particularly because any alteration in the requirements will render all existing documentation and testing obsolete. 37 RNB Global University, Bikaner.

Rapid Application Development Originally conceptualized in the 1970s, the rapid application development model was substantially developed and formalized by James Martin in the early 1990s. It is grounded on the principle that step-by-step structured life cycles inevitably entail delays and errors, urging the need for an alternative methodology. When deadlines are the main priority and the swiftness of software development is critical, RAD presents itself as a very plausible solution. 38 RNB Global University, Bikaner. Course Code - 13004500

Rapid Application Development RAD comprises a set of tools and guidelines that facilitate short-time deployment, within a predefined time frame or “timebox . The product is not developed in successive steps until a final, complete delivery, but rather it evolves in successive increments, following the priorities that are established by business not technical necessities. Some of these tools and guidelines include planning methods, data and process modelling, code generation, testing, and debugging. 39 RNB Global University, Bikaner. Course Code - 13004500

Rapid Application Development It is important to note that both developers and customers are involved in all of the increments. However, teams are generally small, highly skilled, and highly disciplined. They are required to flexibly adapt to eventual changing requirements and feedback from customers. It is crucial to strike the proper balance between flexibility and structural stability. 40 RNB Global University, Bikaner. Course Code - 13004500

Rapid Application Development RAD methodologies can follow three-stage or four- stage cycles. “The four-stage cycle consists of requirements planning, user design, construction, and cutover.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
