Transition engineering methodology

Transition engineering methodology addresses system modification in a cost-effective manner. The methodology effectively collects and uses information about the existing system to plan incremental change. It combines aspects of a prototyping life-cycle development approach with tool for reverse engineering, interface configuration management and component reuse. Transition engineering views the existing system as a prototype and allows the engineer to manage change to the system through the use of interface control, a central feature of the methodology. This allows for evolutionary change at the system level, while making revolutionary change possible within the interface boundaries. It builds in concerns about system reliability and provides economy through maximum component refuse
