The SDLC is composed of four fundamental phases:
• Planning
• Analysis
• Design
• Implementation
• Each of the phases is composed of steps, which rely on
techniques that produce deliverable (specific documents that
explain various elements of the system).
This 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.
THE PLANNING PHASE 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?).
2. During project management, the project manager
creates a work plan, staffs the project, and puts
techniques in place to help the project team
control and direct the project through the entire
SDLC
