TECHNIQUE FOR IMPROVING STAFF QUERIES IN A WORKFLOW MANAGEMENT SYSTEM

A technique for improving staff queries within a process model of a workflow is provided. A workflow management system selects a set of individuals of a staff or resources to perform an activity of the process model based on a staff query. The members of the set act as candidates for executing the activity. The staff query takes into account the requirements needed to successfully execute the particular activity. The particular activity is then executed by one or more resources from the selected set or execution fails. Execution failure means that the assignment to the individual or resource was incorrect due to deficiencies in the staff query. Success or failure of execution is logged in an audit trail. Following execution failure, an improved staff query is generated for the given activity based on the information logged in the audit trail. This avoids subsequent suboptimal assignments of the activity to the individuals or resources. Improving the staff query makes explicit use of data mining techniques on the data maintained in the audit trail.
