The utilization and creation of knowledge in the company's business processes is modeled using the model types available for representing business processes (EPC, EPC (material flow)). The Knowledge category and Documented knowledge object types are now available in these model types. It is possible to specify for a function which kind of knowledge (general or documented) is required for its execution and which knowledge is created and/or documented during its execution. This type of representation enables business processes to be examined in terms of the knowledge processing involved. For example, gaps in required knowledge can be revealed. Besides, the qualification profile needed to carry out a function can be determined.
