Exception handling in workflow management systems (WFMSs) is a very important problem since it is not possible to specify all possible outcomes and alternatives. On the other hand, cooperative support for user-driven computer supported resolution of unexpected exceptions and workflow evolution at run-time is vital for an adaptive WFMS. We have been developing ADOME-WFMS as a comprehensive framework in which the problem of workflow exception handling can be adequately addressed. We present an adaptive exception manager and its Web-based interface for ADOME-WFMS with procedures for supporting the following: effective management of problem solving agents, cooperative exception handling, user-driven computer supported resolution of unexpected exceptions, and workflow evolution.
