“…In particular, [42] presents an approach for adapting well-structured process models without affecting their correctness. Based on this, [43] presents concepts for optimizing process models over time and migrating running processes to new model versions properly. Still, none of these approaches takes usability issues into account, i.e., no support for user-centered changes of business processes is provided.…”

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.

“…Instead, it should be possible to quickly implement new processes, to enable on-the-fly adaptations of running ones, to defer decisions regarding the exact process logic to runtime, and to evolve implemented processes over time. Consequently, process flexibility has been identified as one of the fundamental needs for any PAIS and different enabling technologies have emerged [5][6][7][8]. They support adaptive processes [9][10][11], declarative models [7], late modeling [12,13], and data-driven processes [14,15].…”

“…Adaptations of single process instances (e.g., to add, delete or move activities) become necessary to deal with exceptional situations and often have to be accomplished in an ad-hoc manner [11]. Model changes at the process type level, in turn, have to be continuously conducted to evolve the PAIS [9,5]. It must be also possible to dynamically migrate running process instances to new model versions.…”

Abstract. Process-aware information systems (PAIS) must be able to deal with uncertainty, exceptional situations, and environmental changes. Needed business agility is often hindered by the lacking flexibility of existing PAIS. Once a process is implemented, its logic cannot be adapted or refined anymore. This often leads to rigid behavior or gaps between real-world processes and implemented ones. In response to this drawback, adaptive PAIS have emerged, which allow to dynamically adapt or evolve the structure of process models under execution. This paper deals with fundamental challenges related to structural process changes, discusses how existing approaches deal with them, and shows how the various problems have been exterminated in ADEPT2 change framework. We also survey existing approaches fostering flexible process support.

“…The ADEPT technology, for example, enables controlled changes at the process type as well as the process instance level (for details see [38,39,40]). Thereby, correctness and consistency constraints of a workflow are preserved when dynamically changing its structure, its state, or its attributes during runtime.…”

Abstract. For several reasons enterprises are frequently subject to organizational change. Respective adaptations may concern business processes, but also other components of an enterprise architecture. In particular, changes of organizational structures often become necessary. The information about organizational entities and their relationships is maintained in organizational models. Therefore the quick and correct adaptation of these models is fundamental to adequately cope with organizational changes. However, model changes alone are not sufficient to guarantee consistency. Since organizational models also provide the basis for defining access rules (e.g., actor assignments in workflow management systems or access rules in document-centered applications) this information has to be adapted accordingly (e.g., to avoid dangling references or non-resolvable actor assignments). Current approaches do not adequately address this problem, which often leads to security gaps and delayed change implementation.In this paper we introduce a formal framework for the controlled evolution of organizational models and related access rules. Firstly, we introduce a set of operators with well-defined semantics for defining and changing organizational models. Secondly, we show how to define access rules based on such models. In this context we also define a notion of correctness for access rules. Thirdly, we present a formal framework for the (semi-automated) adaptation of access rules when the underlying organizational model is changed by exploiting the semantics of the applied changes. Altogether the presented approach provides an important contribution for realizing adaptive access control frameworks.
