System Development Life-Cycle

Paper Summary:

This paper discusses system development life-cycle (SDLC), an approach to developing an information system or software product characterized by a linear sequence of steps that progress from start to finish without revisiting any previous step. The author points out that the SDLC model is a project management tool, which is used to plan, execute, and control systems development projects. The paper reviews many models, including the Waterfall Model, which is built upon the basic steps associated with SDLC using a ?top-down? development cycle in completing the system and represents a traditional type of SDLC.

From the Paper:

"Disadvantages identified by Walsham (1993) in relation to the Waterfall Model include that change to contract and costs must be renegotiated if such changes are made once construction has been initiated. As well, users must wait until the end of the project or until at least a major portion of it is complete, before observing the results. Finally, the early phases of the project often take much longer due to the time necessary to generate the detail necessary in the SSD. According to Kay (2002), another major problem associated with the Waterfall Model is that it assumes that the only role for users is in specifying requirements, and that all requirements can be specified in advance."
