Describe THOUGHTFULLY how you learned to understand the differences and benefits of various software engineering lifecycle methodologies. Give two (2) examples from your personal experience of each learning process. (At least one paragraph) For example, we have a short time for software development. There is also a need to fulfill the deadline of deployment of the system. In this scenario, we know that only RAD (rapid application development methodology) is feasible. We know its benefits that how we can take the developed product on time by effectively tracking and managing system development lifecycle. The next example is about the condition of software development when we are going to develop a simple and small system for a business. Here we have enough time and resources. In the scenario, we can use a waterfall development methodology that will well suit the simple system development. Since we use the waterfall model when we have enough time and resources. By understanding the differences and benefits of various software engineering lifecycle methodologies we can be able to evaluate the advantages and problems in initiating a new system development project. In this scenario, we can carry out a cost-benefit analysis of the main resource (time, cost and human) for the overall project development. Thus, if we have deep knowledge and understating of all the aspects of system then we can better estimate the most appropriate development methodology. This will help us complete the system development process on time and within a resource. Each software development project involves its own constraints. And, in presences of these constraints, we can not develop a system effectively. To better develop a system we need to carry out system development analysis and deployment of effective development methodology for its overall development.
