Recently more and more enterprises need to improve their business
processes in the struggle to be competitive. In this area the use of
Workflow Management Systems (WfMS) proved very helpful. The WfMS
ensures the correct execution of previously modelled business
processes. However the modelling of business processes is often a
long and cost intensive task. To improve the efficiency of the WfMS
it is advisable to do continuous reengineering to constantly check
and improve the system.
This work presents the approach of using OLAP technology to do
continuous reengineering and compares OLAP with data mining showing
the advantages of OLAP for this task. By analysing Audit-Trails
written by already executed workflows, it is possible to detect
problems within the basic model of the business process. After
having analysed audit data, the existing workflow models can be
improved. Therefore it is not necessary to define a workflow model
perfectly because it is possible to improve it later. This approach
offers the possibility to increase the advantages you get by using a
WfMS.
This work shows the possibilities of an analysis using OLAP
technology. IBM's MQSeries Workflow shows exemplarily the
possibilities of an OLAP analyses.
