System Development Life Cycle (SDLC)
1. Preliminary Investigation

• Why build the system? Goals, work plan,
  feasibility

2. Analysis

• What is required? Who will use it? Where and
  when?
• Document - DFD and Use Case

3. Design

• How will the system work?
• Design DB, Architecture, interfaces, programs

4. Construct

• Program, test, install, maintain
