Preliminary experience with process modeling in the MARVEL software development environment kernel

The authors define a software development environment kernel called MARVEL. Implementing several prototypes and small environments has uncovered some significant flaws and revealed open design problems. Problems connected with the construction and debugging of a process model, with envelope construction, and with support of multiple users are considered. The authors note that they have investigated only a small fraction of the potential for rule-based process modeling and controlled automation. They observe that they do not yet fully understand how rule-based process modeling or controlled automation works and whether the combination is indeed a solid foundation for a software-development environment architecture
