Collaborative Inter-Organisational Business Processes (IOBPs) are a major step in automating and supporting collaborations of organisations. In this context, collaborative IOBP are usually constrained by hard timing requirements. This paper proposes an approach for analyzing
of collaborative IOBPs. The aim is to verify temporal consistency of IOBP and to provide the enactment service with largest intervals as starting time windows of the processes. The proposed approach enables organisations to detect, early on, temporal inconsistencies that may constitute obstacles towards their interaction. Indeed, it provides an enactment service, which provides each partner with information about temporal restrictions to respect by its own processes in accordance with the overall temporal constraints of all involved processes.
