Over the last twenty years business process management has become a central approach to maintaining the competitiveness of companies. However the automation of the business processes utilizing workflow systems have often led to over-structured solutions that lack of the flexibility inherent in the underlying business model. Therefore there is a need to develop flexible workflow management systems that easily and quickly adapt to dynamically changing business models and processes. Lin and Orlowska (2005) introduced partly complete-able activities as one way to make workflow systems more flexible. In our paper, we extend the concept of partly complete-able activities by recognizing separate probability and fuzzy dimensions and by introducing process memory.
