Each Phases Must be completed before the next phases can begin..
output of one phases can be input of one phases. No Overlapping.


Feasibility study

Determine weather if would be financially & technically feasible.
Requirement Understanding the exact Requirement of the custom.

  • Requirement Gathering
  • Requirement Specification


Design

To Transform The Requirement Specification in The SRS document into Structure.

Coding

Design is  Translated into Source Code.

Integrated Testing
