Coadapting multidimension process properties

Abstract

In the last decades, process verification has been intensively addressed and has become an essential activity to correct and to remove errors before process execution. Typical process verification ecosystems propose to express properties to be verified on the process. A property expresses a desired behavior that must hold or not in the process execution. Processes during their lifespan are continuously adapted for several purposes: enriching, correcting, and refactoring the process. When a process is adapted, the existing properties must naturally be rechecked to ensure that no errors have been introduced, ie, the properties still hold. However, the properties may become outdated and must be coadapted w.r.t. the adapted process before to be rechecked. Otherwise, the verification may raise false alarms or may not detect newly introduced errors. In this paper, we propose a coadaptation approach of properties while considering process adaptation for the different dimensions, namely, control flow, object flow, resources, and timing. We systematically studied process changes in the multiple dimensions to identify those that do impact properties and for which we propose resolution strategies. Our preliminary evaluation shows that our resolutions strategies allow to support users in correctly coadapting impacted properties.
