Issues in workflow and web-based workflow systems

Workflow management systems (WfMSs) have been used for organizational business process re-engineering and automation in various application domains. The use of ubiquitous web as infrastructure of WfMSs widens the applicability of workflow technology to almost every organization. Workflow technology is becoming the core technology for enterprise computing. However, many limitations remain in existing workflow management systems for supporting more demanding applications. In this paper, we address several issues in current workflows management: workflow modeling and verification, transactional support of workflows, and workflow evolution. We also discuss the use of web technology as an infrastructure for supporting WfMSs.
