The process model (PM) of an organization is the specification of the state space and the transition space of the C-world; thus, the set of lawful or possible or allowed sequences of states in the C-world. As we know from Chap. 10, this is to a large extent determined by the transaction pattern. Since every transition in the C-world consists of the creation of a C-result and since there is a one-to-one relationship between this C-result and the causing C-act, these C-acts are also contained in the PM. A C-result and its causing C-act are collectively called a
. The PM specifies also for every process step the information used to perform the step. As a convenient addition, the PM duplicates the knowledge from the CM concerning which actor roles perform the C-acts. They are called
(see Fig. 17.1).
