Computer Science Homework Help

The first step in the analysis process is to create a Preliminary Investigation Report (PIR). The PIR documents the system planning phase of the System Development Life Cycle (SDLC). During the planning phase, the opportunities presented or problem(s) to be solved with an information technology system are identified, investigation into the current situation occurs, and various feasibility aspects of implementing a system are analyzed. This results in a recommendation for further action with estimated costs and schedule, and a list of benefits. Once it is completed and approved, the PIR becomes the major source document for use to begin the systems analysis phase.
