“…Pre-modeling all possible exceptions one can think of makes the process graph very complex and may allow execution paths which are undesired. With the ADEPT2 technology, one could separate exception handling from normal processing and use a knowledge-based system to modify process instances only on demand [51,61,62].…”

This paper gives insights into the ADEPT project. Its target was to develop a next generation process management technology, which is by orders of magnitudes more powerful and flexible than contemporary process management systems. The ADEPT technology should provide advanced features and properties within one system, which seem to exclude each other, but which are required for the support of a broad spectrum of processes: ease-of-use for end users and system developers, high flexibility through the support of non-trivial ad-hoc deviations at the process instance level, quick implementation of process changes through process schema evolution, and correctness guarantees enabling robust execution of implemented processes. This paper describes the background and the real-world cases which motivated our research. It further explains the technological challenges we faced, describes the solutions we elaborated, and discusses the current status of the ADEPT project. Background -how all beganIn 1992 we started the OKIS 1 project -a pretty large and broadly defined 3-years research project funded by the State of Baden-Württemberg. In this project several clinics, medical service units, and the computing center of our university hospital were involved. The goal of OKIS was to develop a concept for a cross-organizational, clinical information system that is able to integrate autonomous, heterogeneous departmental systems as well as to offer services across system boundaries (e.g., scheduling, resource management, and medical data exchange). At the beginning of OKIS we looked at many aspects of hospital information systems to understand the different types of relevant information, the different kinds of information systems involved (e.g., radiology information system, picture archiving and communication systems, and lab systems), the privacy issues, the different types and roles of doctors and nurses, characteristic properties of planning and scheduling tasks, and so forth. We further investigated new developments (at that point in time) like electronic patient record, communication servers, medical guidelines, and computer-assisted medical diagnostics in order to understand which features a modern hospital information system should have [27].The challenge of the service layer we wanted to develop was rather clear in an early stage of the project: Due to the heterogeneity of the underlying systems and the evolutionary nature of the clinical domain one has to decouple service provision from service implementation. However, the discovery of services and their usage must not be complicated. Therefore, long before web services came into the game, we 1 OKIS is derived from the German name of the project and stands for "Open Clinical Database and Information System for the Integration of Autonomous Subsystems".

“…In the literature, a number of similarity measure definitions for agile workflows exist, that require further information in addition to the workflow structure, such as semantic annotations [21], or conversational knowledge [26,25]. The approaches are typically context-aware, that is, the contextual information is considered as a part of the similarity assessment of workflows.…”

Abstract. The agile workflow technology deals with flexible workflow adaptation and overriding, in case of foreseen as well as unforeseen changes and problems in the operating business environment. One key issue that an agile workflow system should address is Business Process (BP) monitoring. This consists in properly highlighting and organizing non-compliances and adaptations with respect to the default process schema. Such an activity can be the starting point for other very critical tasks, such as quality assessment and process reengineering.In this paper, we introduce an automated support to BP monitoring, which exploits the Case-based Reasoning (CBR) methodology. CBR is particularly well suited for managing exceptional situations, and has been proposed in the literature for process change reuse and workflow adaptation support. Our work extends these functionalities by retrieving traces of process execution similar to the current one, which can then be automatically clustered. Retrieval and clustering results can provide support both to end users, in the process instance execution phase, and to process engineers, in (formal) process quality evaluation and long term process schema redefinition. Our approach in practice is illustrated by means of a case study in the field of stroke management.

“…There exist additional challenges not treated here, but which have been considered in the design of the ADEPT2 framework as well: change authorization , change traceability (Rinderle, Reichert, Jurisch, & Kreher, 2006b;Rinderle, Jurisch, & Reichert, 2007b), change annotation and reuse (Weber, Wild, & Breu, 2004;Weber, Rinderle, Wild, & Reichert, 2005c;Weber, Reichert, & Wild, 2006), and change mining (Günther, Rinderle, Reichert, & van der Aalst, 2006;Günther, Rinderle-Ma, Reichert, van der Aalst, & Recker, 2008;Li, Reichert, & Wombacher, 2008b). The given references provide additional reading material on these advanced aspects.…”

In dynamic environments it must be possible to quickly implement new busi ness processes, to enable ad-hoc deviations from the defined business processes on-demand (e.g., by dynamically adding, deleting or moving process activities), and to support dynamic pro cess evolution (i.e., to propagate process schema chan ges to already running process instances). These fundamental requirements must be met without affecting process consistency and robustness of the process-aware information system. In this chapter the authors describe how these challenges have been addressed in the ADEPT2 process management system. Their overall vision is to provide a next generation technology for the support of dynamic processes, which enables full process lifecycle management and which can be applied to a variety of application domains.
