Planning(SDLC)

The planning phase is the fundamental process of understanding why an information system should be built and determining how the project team will go about building it. It has two steps:

1. During project initiation, the system’s business value to the organization is identified: how will it lower costs or increase revenues? Most ideas for new systems come from outside the IS area (from the marketing department, accounting department, etc.) in the form of a system request. A system request presents a brief summary of a business need, and it explains how a system that supports the need will create business value. The IS department works together with the person or department that generated the request (called the project sponsor) to conduct a feasibility analysis. The feasibility analysis examines key aspects of the proposed project:
■ The idea’s technical feasibility (Can we build it?)
■ The economic feasibility (Will it provide business value?)
■ The organizational feasibility (If we build it, will it be used?)
The system request and feasibility analysis are presented to an information systems approval committee (sometimes called a steering committee), which decides whether the project should be undertaken.
 

2. Once the project is approved, it enters project management. During project management, the project manager creates a workplan, staffs the project, and puts techniques in place to help the project team control and direct the project through the entire SDLC. The deliverable for project management is a project plan, which describes how the project team will go about developing the system.
