Abstract: Large open source Software applications based organization like mozila , facebook, google, and AOL are migrating their product towards rapid revision based SDLC Model to release their product as update new revision. The same techniques can be applied to semi automation based software application or developing new application based on existing similar software application using re-usability concept. The newly developed application passes through three processes in parallel development mode to bring better product in shorter time at the lower cost as compared to following any traditional Software development life cycle (SDLC) model. This research investigates the changes in SDLC models after moving to Rapid Revision based software development life cycle model.
