Process landscaping - a method for business process modeling

In this article we describe the method of business process landscaping. It is developed by the experience we made in several process modeling projects dealing with a huge amount of details. A process landscape shows the relations between the processes and serves as a starring point to refine process models on different levels of abstraction. Process landscaping allows to add all derails, but it avoids to loose the overview about process models and their interfaces. We discuss the method in the light of an example from the telecommunications industry, we formalize some of the most important terms around the notion of a process landscape and we use this formalization to formulate some consistency conditions for process landscapes.
