Towards Objective Business Modeling in Enterprise Engineering - Defining Function, Value and Purpose

Current Enterprise Engineering state of the art does not fully address concerns such as bootstrapping and reengineering a working organization from the business perspective. It is currently focused on ontology, the constructional vision, rather than the function. We argue that the function design deserves no less modeling effort, as the construction design draws upon it. To this aim, a change of approach is necessary. By combining knowledge from DEMO, Service Science and e3Value, this paper presents conceptual contributions towards modeling the contribution perspective of a system in an integrated way, namely by defining Function, Value and Purpose. These concepts are first defined in the context of a dual party relationship and then applied to chains of two or more elements. By coupling with an innovative application of the Generic System Development Process, an extension of existing Enterprise Engineering theory is proposed, in a way we believe will assist in improve its current state of the art and widen its application scope.
