Abstract
Knowledge workers often have to navigate through multiple information artefacts to complete their tasks. Business process models and business rule repositories are two such artefacts, which when presented separately are known to cause a lack of shared understanding, conflicts and redundancies that can lead to inefficiencies and even compliance breaches. Although a number of integrated modeling approaches for business processes and rules have been proposed, there is a limited knowledge on how these approaches affect worker behavior and task performance. In this paper, we present the outcomes of an exploratory study undertaken to investigate the behavior of workers performing tasks that require dual artefacts namely business processes and rules. By using a sensemaking lens, our study reveals insights into worker behavior when the representation approach and task complexity is varied. Our results contribute to a better understanding of the sense making processes in various settings and inform modeling practice.
