Enabling Flexibility in Process-Aware Information Systems: Challenges, Methods, Technologies
In todayâs dynamic business world, the success of a company increasingly depends on its ability to react to changes in its environment in a quick and flexible way. Companies have therefore identified process agility as a competitive advantage to address business trends like increasing product and service variability or faster time to market, and to ensure business IT alignment. Along this trend, a new generation of information systems has emergedâso-called process-aware information systems (PAIS), like workflow management systems, case handling tools, and service orchestration engines.
With this book, Reichert and Weber address these flexibility needs and provide an overview of PAIS with a strong focus on methods and technologies fostering flexibility for all phases of the process lifecycle (i.e., modeling, configuration, execution and evolution). Their presentation is divided into six parts. Part I starts with an introduction of fundamental PAIS concepts and establishes the context of process flexibility in the light of practical scenarios. Part II focuses on flexibility support for pre-specified processes, the currently predominant paradigm in the field of business process management (BPM). Part III details flexibility support for loosely specified processes, which only partially specify the process model at build-time, while decisions regarding the exact specification of certain model parts are deferred to the run-time. Part IV deals with user- and data-driven processes, which aim at a tight integration of processes and data, and hence enable an increased flexibility compared to traditional PAIS. Part V introduces existing technologies and systems for the realization of a flexible PAIS. Finally, Part VI summarizes the main ideas of this book and gives an outlook on advanced flexibility issues.

CAiSE Radar 2016
The CAiSE Radar is an experimental format, established for CAiSE 2016, to make CAiSE workshops livelier, exciting, stimulate discussions, and attract additional active participants by establishing an environment where not only well established and validated research is reported but research in infancy, new ideas, and potentially interesting research projects can be presented and discussed. So similarly to a radar, the idea is to enable researchers to look into the future of the field and identify upcoming trends early. The aim of such effort is on one hand to contribute to the building of research communities and promote the integration of young researchers into the community, and on the other hand to provide opportunities to discuss ideas early and to receive additional opinions on planned research
Ontological Evaluation of Conceptual Models
The objective of this paper is to present a philosophically sound approach to conceptual model evaluation. Accordingly, the ontological evaluation of conceptual models is enriched with a linguistic interpretivist perspective. The need for such an approach to evaluation is justified by the substantial economic importance of conceptual models. The quality of a conceptual model has a significant impact on other IT artefacts and, thus, on the costs of IT projects. However, little research has so far focused on their evaluation. In the course of this paper, we develop a framework which describes the current state of research and recognizes neglected research fields. With the aid of this framework we identify a notable shortcoming in conceptual model evaluation research, especially with respect to philosophically sound evaluation procedures. Based on these findings we address the following research questions: What are the shortcomings in current evaluation research, what are the merits of âontological evaluationâ in this context, and how can the linguistic interpretivist approach help to form a comprehensive and philosophically sound conceptual model evaluation approach
Requirements Prioritization Based on Benefit and Cost Prediction: An Agenda for Future Research
In early phases of the software cycle, requirements
prioritization necessarily relies on the specified
requirements and on predictions of benefit and cost of
individual requirements. This paper presents results of
a systematic review of literature, which investigates
how existing methods approach the problem of
requirements prioritization based on benefit and cost.
From this review, it derives a set of under-researched
issues which warrant future efforts and sketches an
agenda for future research in this area
ENVIRONMENTALLY SUSTAINABLE BUSINESS PROCESS MANAGEMENT â DEVELOPING A GREEN BPM READINESS MODEL
During the last half decade, various theories, concepts, and models have been established to make organizations more environmentally sustainable. The IS community had their share with the Green IS/IT domain. As it turned out most of these concepts took a very functional approach, not making a good fit for business process oriented organizations. To fill this gap the research stream of Green Business Process Management (GBPM) arose. In this paper we develop and discuss various capabilities that organizations should have in order to actually take advantage of GBPM. We call these capabilities GBPM readiness
Design-time Models for Resiliency
Resiliency in process-aware information systems is based on the availability of recovery flows and alternative data for coping with missing data. In this paper, we discuss an approach to process and information modeling to support the specification of recovery flows and alternative data. In particular, we focus on processes using sensor data from different sources. The proposed model can be adopted to specify resiliency levels of information systems, based on event-based and temporal constraints
Picking battles: The impact of trust assumptions on the elaboration of security requirements
This position paper describes work on trust assumptions in the con-text of security requirements. We show how trust assumptions can affect the scope of the analysis, derivation of security requirements, and in some cases how functionality is realized. An example shows how trust assumptions are used by a requirements engineer to help define and limit the scope of analysis and to document the decisions made during the process
