System Development Life Cycle Pros And Cons

Although the SDLC (System Development Life Cycle) has many strengths and is still used today, it equal has many potential weaknesses which have led to alternative methodologies, techniques, and tools creation available. (Avison & Fitzgerald, 2003). The System Development Life Cycle is outlined as a method of logical processes that a team of professionals may use to approach a project to develop a computer remains for a customer (Dennis et al, 2006.

This is achieved by breaking the project down into more manageable pieces. Also, t his placement promotes the heavy documentat! ion of all events in the process, which means the form is easier later on to understand. This documentation is crucial in non solo maintaining the system, but also in future improvements.
