    An approach to quantify the costs of business process intelligence
    (Enterprise modelling and information systems architectures, 2005) Mutschler, Bela; Bumiller, Johannes; Reichert, Manfred
    Today, enterprises are forced to continuously optimize their business as well as service processes. In this context the process-centered alignment of information systems is crucial. The use of business process intelligence (BPI) tools offers promising perspectives in this respect. However, when using BPI tools one has not only to look at potential benefits but at costs as well. Therefore, most enterprises thinking about the purchase of a BPI solution demand for a business case systematically outlining an investment's benefits and costs. This paper summarizes such a business case based on an evaluation of contemporary BPI tools and practical experiences. We present basic BPI concepts, describe BPI benefits and cost drivers and introduce two cost models to gain insights into BPI economics.

    BPMN extension for business process monitoring
    (Enterprise modelling and information systems architectures - EMISA 2014, 2014) Baumgraß, Anne; Herzberg, Nico; Meyer, Andreas; Weske, Mathias
    The execution of business processes generates a lot of data representing happenings (also called events) that may be utilized for process monitoring and analysis. This, however, is not supported by typical Business Process Management Systems (BPMSs). Especially, in manual executing business process environments, i.e., not driven by a BPMS, the correlation of events to processes for monitoring and analysis is not trivial. At design-time, Process Event Monitoring Points are used in process models to specify the locations, where particular events are expected. Therewith, occurring events can be assigned to a process during run-time. In this paper, we introduce an extension to BPMN, which implements this connection between process models and events. We show applicability of this extension by applying it to a logistics scenario taken from an EU project.

    Bringing innovative semantic technology to practice: The iQser approach and its use cases
    (Informatik 2009 – Im Focus das Leben, 2009) Wurzer, Jörg; Mutschler, Bela
    This paper presents the iQser approach, a new semantic technology promising to overcome some of the shortcomings of current semantic enterprise solutions. The iQser technology is based on a powerful middleware platform (called iQser GIN platform). This practically-approved platform enables enterprises to efficiently develop effective semantic applications integrating various sources of structured and unstructured data. Goal is to enable users to gain new insights into complex information domains. In order to illustrate the practical relevance of the approach the paper also discusses potential enterprise computing use cases such as business (process) intelligence and information retrieval and also describes demo applications that have been already developed.

    Business process as a service - status and architecture
    (Enterprise modelling and information systems architectures - EMISA 2014, 2014) Barton, Thomas; Seel, Christian
    A Cloud Service is usually classified as Infrastructure as a Service, Platform as a Service or Software as a Service. This classification ist not sufficient, when Business Processes are considered. Therefore, Business Process as a Service (BPaaS) as next level of abstraction is in discussion. BPaaS is already an important topic for analysts and cloud providers. In the scientific community a discussion about BPaaS has been started. This contribution presents a literature analysis of the current state-of-the-art in BPaaS. In order to investigate how a Business Process can be built on top of a cloud service, a prototpye of an external application is presented, which is built on top of a cloud service using a RESTful API. For the realization of BPaaS existing architectures for cloud computing are discussed. A proposal for an advanced Architecture for Business Process as a Service is presented. Based on these findings, a brief outlook on future research questions concerning Business Process as a Service is derived.

    Choosing an adequate level of detail in business process modelling
    (Enterprise modelling and information systems architectures - EMISA 2014, 2014) Nissen, Volker; Heyn, Christian; Termer, Frank
    It is a basic matter of business process modelling to determine an adequate level of model detail, a problem which also can be derived from the guidelines of modelling by Becker et al. [BRU00]. In literature, only few recommendations how to solve this problem can be found. In addition they are quite unspecific and have gaps. In this paper, we investigate which measurable factors influence the adequate detail level, and on this basis make proposals for guidelines how it can be determined in a specific application situation.

    Designing and implementing a framework for event-based predictive modelling of business processes
    (Enterprise modelling and information systems architectures - EMISA 2014, 2014) Becker, Jörg; Breuker, Dominic; Delfmann, Patrick; Matzner, Martin
    Applying predictive modelling techniques to event data collected during business process execution is receiving increasing attention in the literature. In this paper, we present a framework supporting real-time prediction for business processes. After fitting a probabilistic model to historical event data, the framework can predict how running process instances will behave in the near future, based on the behaviour seen so far. The probabilistic modelling approach is carefully designed to deliver comprehensible results that can be visualized. Thus, domain experts can judge the predictive models by comparing the visualizations to their experience. Model analysis techniques can be applied if visualizations are too complex to be understood entirely. We evaluate the framework's predictive modelling component on real-world data and demonstrate how the visualization and analysis techniques can be applied.

    On the usability of business process modelling tools - a review and future research directions
    (Enterprise modelling and information systems architectures - EMISA 2014, 2014) Shitkova, Maria
    The choice of a business process modelling (BPM) tool in combination with the selection of a modelling language is one of the crucial steps in BPM project preparation. Different aspects influence the decision: tool functionality, price, modelling language support, etc. In this paper we discuss the aspect of usability, which has already been recognized as an important topic in software engineering and web design. We conduct a literature review to find out the current state of research on the usability in the BPM field. The results of the literature review show, that although a number of research papers mention the importance of usability for BPM tools, real usability evaluation studies have rarely been undertaken. Based on the results of the literature analysis, the possible research directions in the field of usability of BPM tools are suggested.
