Managing process model complexity via concrete syntax modifications

This is the latest version of this eprint.

Abstract

While Business Process Management (BPM) is an established discipline, the increased adoption of BPM technology in recent years has introduced new challenges. One challenge
concerns dealing with the ever-growing complexity of business process models. Mechanisms for dealing with this complexity can be classified into two categories: i) those that are solely concerned with the visual representation of the model, and ii) those that change its inner structure. While significant attention is paid to the latter category in the BPM literature, this paper focuses on the former category. It presents a collection of patterns that generalize and conceptualize various existing mechanisms
to change the visual representation of a process model. Next, it provides a detailed analysis of the degree of support for these patterns in a number of state-of-the-art languages and tools. The paper concludes with the results of a usability evaluation of the patterns conducted with BPM practitioners.
