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 universe 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. P.4.). It was designed to amend on the stepwise very basic method which in turn had replaced the two-phase method which involved going straight to the zip stage and from then on merely patching the regulation as they went along (Leffingwell and Widrig, 2003. p.24.). However, according to Hoffer et al, the number of identified phases in this method varies from between 3 and 20 (depending on the textual matter authors and individual organisations (Hoffer et al, 2009.

Royce in 1970 (Royce, 1970).

The SDLC method gives developers some guidance on what should and shouldnt be developed. Through this method the developers are able to key detailed plans on how and then actually build the dust. This is achieved by breaking the project down into more manageable pieces. Also, this governin g body promotes the heavy documentation of a! ll events in the process, which means the frame is easier later on to understand. This documentation is crucial in non unless maintaining the system, but also in future improvements. Leffingwell and Widrig(2003. p.24.) evoke that each(prenominal) step in the Waterfall method cannot generate without the foregoing step being completing as it depends on the forward work.
