Methodologies and CASE tools-the missing link

A generalized logical model for CASE tools, which is designed as a `methodology generator´ for system development, is presented. The model is applied using the SuitCASE workstation, which enables all parties involved in system development to computerize development methodologies and to build up a set of computerized standards for supporting all life-cycle phases. During a one-year trial period, about 50 projects were implemented with the help of the software, within the framework of system analysis courses. It soon became clear that the model-which was initially constructed for learning purposes-is also effective for organizations, computer units, and software houses who are involved with developing information systems. Experience running the software during a two-year period demonstrated that the process of adapting to the product is simple and convenient. Full control of the operation kit of the product requires an investment of four hours of training and exercises. The most sophisticated operation kit requires five additional hours of training
