“…For example, business process models (process models for short) have been employed in the context of process-aware information systems, service-oriented architectures and web services [2]. Recently, declarative approaches have received increasing attention due to their flexibility with respect to modeling and execution of processes [3]. While imperative process models specify exactly how things must be done, declarative models focus on the logic that governs the interplay of process actions by describing activities that may be performed as well as constraints prohibiting undesired behavior.…”

Abstract. Declarative approaches to business process modeling are regarded as well suited for highly volatile environments, as they enable a high degree of flexibility. However, problems in understanding declarative process models often impede their adoption. Particularly, a study revealed that aspects that are present in both imperative and declarative process modeling languages at a graphical level-while having different semantics-cause considerable troubles. In this work we investigate whether a notation that does not contain graphical lookalikes, i.e., a textual notation, can help to avoid this problem. Even though a textual representation does not suffer from lookalikes, in our empirical study it performed worse in terms of error rate, duration and mental effort, as the textual representation forces the reader to mentally merge the textual information. Likewise, subjects themselves expressed that the graphical representation is easier to understand.

Abstract. The increasing adoption of process-aware information systems (PAISs) has resulted in large process model collections. To support users having different perspectives on complex processes and related data, a PAIS should enable personalized process views, i.e., user-specific abstractions of process models. Despite the abstraction achieved through views of the graphical process models, many end users still struggle with understanding these graphical models and their details. For selected user groups, therefore, a PAIS should provide verbalized process descriptions describing their role in the process. Existing PAISs neither provide mechanisms for managing process views nor verbalized process descriptions. While process views have been used as visual abstractions for large process models, so far no work exists on how to provide both personalized and verbalized process descriptions based on respective views. This paper presents an approach for creating such personalized and verbalized process descriptions based on process views. Furthermore, textual changes of a personalized and verbalized process description are correctly mapped to corresponding updates of the underlying process model. In this context, all other views and process descriptions related to this process model are migrated to the new version of the process model as well. Overall, our approach enables end users to understand and evolve large process models based on personalized and verbalized process descriptions.

Service choreographies support a distributed composition approach that is based on the specification of the external interaction of the participant services in terms of flows of message exchanges, given from a global perspective. When developing distributed service-based applications, different services are produced by different teams; at the same time, such choreographies can also interact with third-party services, hence leading to the reuse of black-box services. Enforcing a global coordination logic across the many in-house and third-party services to correctly realize the specified choreography is a nontrivial endeavor. Automatic support is then desirable. In this article, we present an integrated development and run-time environment for choreography-based systems, which covers all the development activities, including specification, code synthesis, automatic deployment, enactment, and monitoring on the Cloud. We focus on providing a practical solution, that is, applicable by the community and considering technological standards used in the industry. We report the results of an experiment that we conducted with a use case in the in-store marketing and sales domain. Results confirm confidence in the approach and show that the platform can be applied in practical contexts.
