The paradigm shift from traditional BPM to Subject-oriented BPM (S-BPM) is accounted to identifying independently acting subjects. As such, they can perform arbitrary actions on arbitrary objects. Abstract State Machines (ASMs) work on a similar basis. Exploring their capabilities with respect to representing and executing S-BPM models strengthens the theoretical foundations of S-BPM, and thus, validity of S-BPM tools. Moreover it enables coherent intertwining of business process modeling with executing of S-BPM representations. In this contribution we introduce the framework and roadmap tackling the exploration of the ASM approach in the context of S-BPM. We also report the major result, namely the implementation of an executable workflow engine with an Abstract State Machine interpreter based on an existing abstract interpreter model for S-BPM (applying the ASM refinement concept). This workflow engine serves as a baseline and reference implementation for further language and processing developments, such as simulation tools, as it has been developed within the Open-S-BPM initiative.

Today's business requires stakeholders to get involved in organizing work and developing organizational processes, ranging from product life cycle management to crossboundary networking of organizations. In that context stakeholders continuously and iteratively need to address their business and knowledge processing environment at the same time. When the business processing environment is concerned, the adaption of work procedures in-use takes center stage. Going beyond operation affects learning, and thus the knowledge processing environment. Hereby, proposals to (fundamentally) change existing work processes are handled. Each input needs to be formulated as knowledge claim, before being investigated for taking decisions on modifying currently implemented processes. The design of corresponding support technologies requires highly flexible, since context-aware architectures. We introduce a corresponding component framework for design support. It features organizational development based on articulating and processing work-relevant knowledge for changing affected business processes. As the framework is open to different implementations versatile interactive solutions can be generated in dynamically evolving settings.
