Projects during products phase can still be updated, modified through smaller projects. This entire process of building, deploying and updating the information system is called system development life cycle (SDLC).

There are two kinds of SDLCs approaches, one is predictive and another one is adaptive. A predictive approach which is organised and planned well in advance and new information can be developed according to the plan. While adaptive approach is when the exact requirement or user’s need are not known in advance. In this approach, some requirement of the system has be to determined after the initial development work. Generally projects have both the approaches. Predictive approaches are more traditional and were invented in 1970. Most of the adaptive approaches are created during 1990.
