There are three major Phases -
1. The Pre-Development Phase
2. Development and Implementation
3. Product Maintenance.
Each of these phases have various Milestones like commencement of
the Project, Project Launch/Feasibility Study, Preliminary Requirements
Development etc. and each of these Milestones will have one or more
The first phase is Conceptualization of the Idea The 'idea'
is screened for technical and economic feasibility in the "Pre-Development
Phase" (PDP). If required, a prototype model is also built
during this phase to prove the concept. Initiation of this phase
is to be approved by MRB/Review Team. Based on the results of this
phase, Management may decide to go ahead with the product development
and in that case the project is initiated and the System Development
Life Cycle (SDLC) phase begins.
The "Development and Implementation Phase" is the
second phase. It may be possible that one PDP may lead to a number
of sub-projects and in that case a number of independent SDLC's
would begin. It may be necessary to integrate the various sub projects
into one final product. It would also be essential that all the
teams working on the sub projects maintain close interaction so
that the focus on the end product is not lost. SDLC constitutes
a significant portion of the PDLC. These activities, although are
identified here, are explained in detail separately in the Quality
Management System. After the development, the product undergoes
Alpha and Beta testing and Launch of the Product takes place. Once
the product is launched, then it enters the third phase, which is
"Product Maintenance Phase".
