In the previous chapters of Part C, the Ψ-theory has been presented and discussed. In order to utilize the benefits of this theory in practice, a meta model for modeling organizations, called the CRISP model, is presented in this chapter. As we will see, this meta model allows us to construct enterprise ontologies according to the Ψ-theory. We will define the ontology (or the ontological model) of an enterprise as the conceptual model of its Borganization according to the CRISP model. Because we are going to deal with both facta and stata (Chap. 4), we will generally avoid the term “fact” in this chapter.
