An open integrated CAx-framework supplies services to build derived CAx-environments (e.g. for concurrent Engineering (CE), VLSI-design, Software Engineering, etc.) with specialized, integrated in-house or foreign tools. Such integrated tool uses services of the CAx-framework and cooperates with other integrated tools to achieve a common engineering objective like the simulation of a VLSI-circuit. In most CAx-frameworks the integrated tools cooperate indirectly using CAx-framework services like Data Handling or Inter-Tool Communication (ITC).With obTIOS a high-level approach to control cooperation of integrated tools within a Computer Aided Concurrent Engineering (CACE) environment is introduced. The tools of a CACE-environment are grouped to domains which represent the most coarse, mutually independent, structural unit within the CACE-environment. The way in which the tools of a domain cooperate is described by Encapsulated Composed Activities (ECA). An ECA represents a template of control regarding cooperation-in-the-large and cooperation-in-the-small of tools.
