Generic Core Life Cycle and Conceptual Architecture for the Development of Collaborative Systems

In the conventional system development life cycle (SDLC), the system performance evaluation phase comes after the implementation phase. Our strategy is to project system performance estimate at the requirement analysis and design phase itself much before the implementation phase. To achieve this objective, we propose a technology-neutral integrated environment for the core life cycle of system development. This core life cycle consists of three phases: system modelling, performance evaluation and performance improvement.
