Trust-aware business processes with distributed ledger technologies [article]

Marcel Müller, Technische Universität Berlin, Axel Küpper
The progressing digital transformation and internationalization of business processes cause a shift towards a more collaborative nature of processes. In such collaborations, different organizations execute separate parts of the process autonomously. This fragmentation leads to uncertainty regarding the correct execution of activities, the proper workflow, and data flow. If organizations engage in business together, trust is required. Current research identified blockchain and distributed ledger

This thesis proposes three design science artifacts for analyzing and creating trust-aware business processes using distributed ledger technologies. Firstly, TAPE is a method for trust-aware business process engineering. The TAPE method consists of three steps. The first step analyzes trust issues in business processes. Therefore, TAPE uses a business process model and a trust model for joint semantical analysis. TAPE's second step uses trust patterns to mitigate trust issues in a collaborative business process. The last step of the TAPE method implements the trust-aware process. The second artifact that this thesis proposes is Trust Studio. Trust Studio is a web application that aids process analysts and engineers in applying the TAPE method. The last artifact this thesis introduces is a set of distributed ledger trust patterns. These trust patterns are classified with a taxonomy that helps to identify their trust-enhancing capabilities. A set of different evaluation methods assesses the utility of the introduced design science artifacts. The evaluation shows that all three contributions reached the status of a minimal viable artifact. Thus, the outcomes of this thesis foster a deep understanding of trust in business processes and how distributed ledger technologies can be utilized as a tool to mitigate trust issues.
