Extending Business Process Models with Appreciation

Alain Wegmann, Gil Regev, Irina Rychkova

We use homeostasis, the maintenance of steady states in an organism, to explain some of the decisions made by participants in a business process. We use Vickers’ Appreciative System to model the homeostatic states with Harel’s statecharts. We take the exam ...

A Novel Approach to Modeling Enterprise Services Leveraging Object Cloning and Multilevel Classification

Alain Wegmann, Lam Son Lê

Object-oriented modeling is concerned with capturing common properties of objects. The dominant thinking in this realm is to classify objects that share certain properties into what is called a class, which in turn enables us to instantiate additional obje ...

Comparison of Two Value-Modeling Methods: e3 value and SEAM

Alain Wegmann, Gil Regev, Blagovesta Hristova Kostova

In the last few decades, several value-modeling methods have emerged in requirements engineering for IS research. We compare two value-modeling methods, e3value and SEAM. We illustrate their use with an example of the exchange of the Intellectual Property ...

Ontology for SEAM Service Models

Alain Wegmann, Gorica Tapandjieva Sekulovska

A service system is a popular concept in academia and industry. At the same time, it is a challenging concept to represent, due to its recursive nature and difficulty to relate it to entities in reality. In this paper we present an ontology for modeling se ...
