Balancing Between Flexibility and Support
Today’s process-aware information systems tend to either support business processes or provide flexibility. Classical workflow management systems offer good process support as long as the processes are structured and do not require much flexibility. Information systems that allow for flexibility have a tendency to lack processrelated support. If systems offer guidance, then they are typically a...
متن کاملTowards Analyzing Declarative Workflows
Enacting tasks in a workflow cannot always follow a predefined process model. In application domains like disaster management workflows are partially specified and circumstances of their enactment change. There exist various approaches for formal workflow models that are effective in such situations, like declarative specifications instead of operational models for formalizing flexible workflow...
متن کاملConcurrency & Asynchrony in Declarative Workflows
Declarative or constraint-based business process and workflow notations, in particular DECLARE and Dynamic Condition Response (DCR) graphs, have received increasing interest in the last decade as possible means of addressing the challenge of supporting at the same time flexibility in execution, adaptability and compliance. However, the definition of concurrent semantics, which is a necessary fo...
متن کاملFlexibility for Distributed Workflows
This chapter shows how flexibility can be realized for distributed workflows. The capability to dynamically adapt workflow instances during runtime (e.g., to add, delete or move activities) constitutes a fundamental challenge for any workflow management system (WfMS). While there has been significant research on ad-hoc workflow changes and on related correctness issues, there exists only little...
متن کاملOn the interplay between flexibility and support
Today’s information systems do not support adaptive workflow: either the information system abstracts from the workflow processes at hand and focuses on the management of data and the execution of individual tasks via applications or the workflow is supported by the information system but it is hard to handle changes. This paper addresses this problem by classifying the types of changes. Based ...
