1. First phase : Recognition of need
The trends of increasing technical complexity of the systems, coupled with the need for repeatable and predictable process methodologies, have driven System Developers to establish system development models or software development life cycle models.
2. Second Phase : Feasibility Study
Feasibility for a system means whether it is practical and beneficial to build that system.
1.Technical feasibility: Can the development of the proposed system be done with current equipment, existing software technology, and available personnel? Does it require new technology?
2. Economic feasibility: Are there sufficient benefits in creating the system to make the costs acceptable? An important outcome of the economic feasibility study is the cost benefit analysis.
3. Legal feasibility: It checks if there are any legal hassle in developing the system.
4. Operational feasibility: Will the system be used if it is developed and implemented? Will there be resistance from users that will undermine the possible application benefits?
3. Third phase : Analysis

Sampling
Questionnaires
Interviews
Observations
Research
4. Fourth Phase : Design
5. Fifth Phase : Development, Implementation & Testing
