Towards a comprehensive understanding of the context concepts in context-aware business processes

Recent studies explore context-awareness as a new paradigm and principle in BPM (Business Process Management). However, there is still a lack of consensus on the meaning of context related concepts in the BPM area. While most people tacitly understand what context is and use context to optimize business processes, they find it hard to define. Researchers commonly provide their own definitions according to their own background and expertise, which leads to diversity and inconsistency. Hence, this paper provides a comprehensive understanding of the context concepts of context-aware BPM based on an extensive literature review. We excessively review and analyze existing definitions of the context concept, and propose a pyramid model to depict the trade-off between generalization and specification. Definitions of context-aware business processes have been derived from various perspectives of how a business process can potentially benefit from being aware of its context, which can be broadly classified to three categories including process flexibility, personalized services and knowledge-intensive tasks. Then we propose our definitions of the context of a business process and the context-aware business process, which can be used in general applications. In addition, context related concepts of business processes, including context-sensitive, -aware and -adaptive business processes, are clarified and distinguished to set the theoretical foundation of context-aware BPM consistently.
