In this week’s reading assignment, an interesting takeaway that I think is important to mention is about a system development methodology. According to the textbook, a systems development methodology is a structure that an organization uses to plan and control the development of information systems and software and new business applications. The textbook also mentions three different types of models that can be used for a system development methodology. These three models are known as Traditional waterfall, V-shaped, and Iterative. According to the book, the traditional SDLC (waterfall) model and variants of the model normally involve a life cycle verification approach that ensures that potential mistakes are corrected early and not solely during final acceptance testing. V-shaped models focus on the relationship between development phases and testing levels. V-Shape models are the most vague testing, the unit test and occurs immediately after programs have been written in code. And the iterative model is a cyclical process in which business requirements are developed and tested until the entire application is designed and tested to be launched. During each iteration, the development process goes through each phase, from requirements through testing, and each subsequent cycle incrementally improves the processes and efficiencies of the system.
