Systems Development life Cycle (SDLC) ➢ The traditional methodology used to develop, maintain, and replace information systems. ➢ The evolution of process that is followed in implementing a computer-based information system subsystem. ➢ Also known as Systems life cycles, Systems Development Methodology, Project Life Cycle, and Methodology.

Purpose: ➢ To define the activities to be carried out in a system development project. ➢ To introduce consistency among many systems development projects in the same organization. ➢ To provide checkpoints for management control for go/no-go decisions.

SDLC Phases:

Project Planning

Requirements Determination

Analysis

Design

Implementation

Maintenance

Planning Phase:

STEPS: 1. Recognize the problem ➢ What is a problem? ➢ When is a problem advantageous?

2. Define the problem ➢ Is it the correct problem?

3. Set system objectives
