Summary. Companies increasingly adopt process-aware information systems (PAISs) to model, enact, monitor, and evolve their business processes. Although the proper handling of temporal constraints (e.g., deadlines and minimum time lags between activities) is crucial for many application domains, existing PAISs vary significantly regarding the support of the temporal perspective of a business process. In previous work, we introduced characteristic time patterns for specifying the temporal perspective of PAISs. However, time-aware process schemas might be complex and hard to understand for end-users. To enable their proper visualization, therefore, this paper introduces an approach for transforming time-aware process schemas into enhanced Gantt charts. Based on this, a method for creating personalized process schedules using process views is suggested. Overall, the presented approach enables users to easily understand and monitor time-aware processes in PAISs.

SUMMARY The need for flexible process‐aware information systems resulted in a recent interest in declarative approaches, as they promise a high degree of flexibility. However, the potential of current declarative approaches is impeded by deficiencies in understandability and maintainability. This paper proposes an approach toward better understandability and maintainability of declarative processes by adopting well‐established techniques from the domain of software engineering. More specifically, the ideas of test‐driven development and automated acceptance testing are adopted to interweave process specification and process testing. Thereby, during modeling, testcases balance the circumstantial/sequential information mismatch as well as improve understandability by dispensing with hard mental operations and removing hidden dependencies. Because testcases are also understandable to domain experts, they foster communication between domain experts and model builders, providing a common basis for communication. During process execution, testcases, in turn, help to document the reasons for process deviations and ensure that respective deviations can be easily considered during schema evolution. Furthermore, testcases ensure that no undesired behavior is introduced through process adaptations. Copyright © 2011 John Wiley & Sons, Ltd.
