Today, companies are driven by the rate at which technologies change and move towards global enterprises and virtual organizations in order to stay competitive. In global and virtual enterprises, business processes consist of multiple sub-processes that may span multiple time zones, organizational boundaries, and legal domains. Current workflow technology does not provide the necessary functionality to model, implement, and manage such processes due to its mostly centralized, coupled architecture and limited process management capabilities. In this paper, we present our on-going efforts to address some of these shortcomings. In particular, we outline an event-based workflow infrastructure that support distributed, heterogeneous, and dynamically changing environments. In addition, we present time-related constructs for addressing the time aspects of processes in such environments.
