To realize the open and global software marketplace and to enable the virtual enterprise along with software life-cycle, we have completed a two year project named the NGSE (Next Generation Software Engineering) program which is ?? part of Software CALS (Continuous Acquisition and Lifecycle Support) project sponsored by IPA (Information technology Promotion Agency). The NGSE program developed and demonstrated the enabling technologies for CBSD (Component-Based Software Development) or Componentware, which consist of technology standards, application guidelines and environments for sharing software information and providing network security. This paper reports the results of the NGSE program including the business model and experiments of CBSD. We discuss the following CBSD technologies for the enabling cooperative software development in a distributed object environment.E Component trading on Internet E Software integration technologies using prefabricated software components E System integration technologies E Internet security technologies From these experiments, we can conclude the proposed CBSD enabling technologies for next generation software engineering is feasible.
