The method, which is part of an integrated design and performance evaluation method, addresses the design of client/server software architectures, where the servers need to cooperate with each other to service client requests. The goal of this… (More)
Through methodological evolution, the development of the Knowledge-Based Development Life Cycle is supported. In this methodology, processes replace phases and stages and during system development, dynamic activation of processes allows the system to evolve.
