Abstract
En 中文
Business Process Management provides concepts for enterprises to design, document and execute their business processes. Involved artefacts establish the basis for a profound enhancement of processes, like performance improvements or a substantiate assignment of employees (resources) to tasks. These artefacts comprise process models for documentation purposes or Workflow Management Systems for executing processes. Those concepts are adopted well within single companies but are barely implemented for inter-organizational processes reasoned in a lack of trust between participating business partners. For instance, questions like who the host of the workflow engine is and thus have sovereignty over the process execution remains open. Besides expensive third parties, we believe that Blockchain Technology bears potential to solve the lack of trust due to automated consensus finding. We present a Blockchain-based process engine guaranteeing a tamper-proof execution, which is both, highly scalable regarding the size of process models as well as capable of considering employees captured in the organizational perspective of the process model. Comparable approaches suffer from lack of trustworthiness either, are not applicable for large process models, or do not include organizational concerns. (C) 2019 Elsevier B.V. All rights reserved.
