workflow performance evaluation through wpql
The problem of performance evaluation of business processes supported by Workflow Management Systems is a recent research issue. In this paper, we propose an approach to the performance evaluation of automated business processes based on the measurement language WPQL (Workflow Performance Query Language). The paper first describes the WPQL architecture together with a selection mechanism by means of which the workflow entities to measure are isolated. Then, the main constructs of WPQL for measure definition and measure application are presented and exemplified. Finally, we show a working session of the support tool and discuss some guideline for further research.
