THE SYSTEM DEVELOPMENT LIFE CYCLE(SDLC)

SDLC describes the development of a system from the time it is first studied until the time it is put into use. It can be used to both a large corporation or a home office PC.

Each step results in some type of documentation that move on to the next step.These six steps do not always follow one another in a strict sequence.

Ex: the analysis and design are interwoven and modified and skipped along with the process development

Preliminary investigation

DOCUMENTATION: FEASIBILITY REPORT

The main output of the preliminary investigation.

Includes : The systems analyst’s findings on the status of the existing system. The benefits and feasibility of changing to a new system.

Measuring feasibility: Using a few different perspectives. Personnel needed to implement the new system.

Feasibility report also contains the systems analyst’s recommendations.
