In this paper we are proposing a view of modelling which is based on a process-ontological modelling. Firstly we will consider different kinds of definitions for processes, and how these influence thinking in software engineering. Secondly, we define the basic modelling situation and different ways of its using. Thirdly, we will describe the problem of a common process connected with a mechanical view of processes, which we are compared with an alternative view based on process-ontological view. Lastly, we will introduce a Process-Ontological Model, (POM), according to which everything can be seen as processes. We are proposing that by means of process-ontological modelling we are able make a wider and more flexible view to modelling situations.
