=== Levels of technical granularity ===

The description of system elements on different levels of technical granularity supports a systematic development of collaborative information systems, starting with the business requirements definition and going all the way down to the code level. Apart from the construction aspect, thereby also a multi-dimensional interoperability description is also provided;, describing the interacting systems on different levels of technical granularity enablesfacilitating the synchronization of the collaborating systems on each level. Similar to for example [[Architecture of Integrated Information Systems|ARIS]] and OMG's [[Model-driven architecture|MDA]] three levels are used:

# Business Level: Here the processes to be automated are described from a technique independent level. In MDA this level is referred to as CIM level.

# Technical Level: Here the IT concept is described. Therefore, the models from the first level are technically enriched, for example, instead of business functions now components are described, but still on a coarse-grained, conceptual level. Since the models on the second level represent the basis for an automated generation of executable code, they might have to be further adapted to fit implementation level constraints.
