- As a result of the growing adoption of Business Process Management (BPM) technology, different stakeholders need to understand and agree upon the process models that are used to configure BPM systems. However, BPM users have problems dealing with the complexity of such models. Therefore, the challenge is to improve the comprehension of process models. While a substantial amount of literature is devoted to this topic, there is no overview of the various mechanisms that exist to deal with managing complexity in (large) process models. As a result, it is hard to obtain an insight into the degree of support offered for complexity reducing mechanisms by state-of-the-art languages and tools. This paper focuses on complexity reduction mechanisms that affect the abstract syntax of a process model, i.e. the formal structure of process model elements and their interrelationships. These mechanisms are captured as patterns so that they can be described in their most general form, in a language- and tool-independent manner. The paper concludes with a comparative overview of the degree of support for these patterns offered by state-of-the-art languages and tools, and with an evaluation of the patterns from a usability perspective, as perceived by BPM practitioners.

- While Business Process Management (BPM) is an established discipline, the increased adoption of BPM technology in recent years has introduced new challenges. One challenge concerns dealing with the ever-growing complexity of business process models. Mechanisms for dealing with this complexity can be classified into two categories: i) those that are solely concerned with the visual representation of the model, and ii) those that change its inner structure. While significant attention is paid to the latter category in the BPM literature, this paper focuses on the former category. It presents a collection of patterns that generalize and conceptualize various existing mechanisms to change the visual representation of a process model. Next, it provides a detailed analysis of the degree of support for these patterns in a number of state-of-the-art languages and tools. The paper concludes with the results of a usability evaluation of the patterns conducted with BPM practitioners.

- Process mining techniques can be used to analyse business processes using the data logged during their execution. These techniques are leveraged in a wide range of domains, including healthcare, where it focuses mainly on the analysis of diagnostic, treatment, and organisational processes. Despite the huge amount of data generated in hospitals by staff and machinery involved in healthcare processes, there is no evidence of a systematic uptake of process mining beyond targeted case studies in a research context. When developing and using process mining in healthcare, distinguishing characteristics of healthcare processes such as their variability and patient-centred focus require targeted attention. Against this background, the Process-Oriented Data Science in Healthcare Alliance has been established to propagate the research and application of techniques targeting the data-driven improvement of healthcare processes. This paper, an initiative of the alliance, presents the distinguishing characteristics of the healthcare domain that need to be considered to successfully use process mining, as well as open challenges that need to be addressed by the community in the future.

Open source workflow : A viable direction for BPM? Extended abstract

- With the growing interest in open source software in general and business process management and workflow systems in particular, it is worthwhile investigating the state of open source workflow management. The plethora of these offerings (recent surveys such as [4,6], each contain more than 30 such systems) triggers the following two obvious questions: (1) how do these systems compare to each other; and (2) how do they compare to their commercial counterparts. To answer these questions we have undertaken a detailed analysis of three of the most widely used open source workflow management systems [1]: jBPM, OpenWFE, and Enhydra Shark. Another obvious candidate would have been the open-source workflow management system YAWL ( www.yawlfoundation.org ). However, given the authors’ close involvement in the development of YAWL, we did not include it in our evaluation.

Tidskriftsartikel (refereegranskat)abstract
- In keeping with the proliferation of free software development initiatives and the increased interest in the business process management domain, many open source workflow and business process management systems have appeared during the last few years and are now under active development. This upsurge gives rise to two important questions: What are the capabilities of these systems? and How do they compare to each other and to their closed source counterparts? In other words: What is the state-of-the-art in the area?. To gain an insight into these questions, we have conducted an in-depth analysis of three of the major open source workflow management systems - jBPM, OpenWFE, and Enhydra Shark, the results of which are reported here. This analysis is based on the workflow patterns framework and provides a continuation of the series of evaluations performed using the same framework on closed source systems, business process modelling languages, and web-service composition standards. The results from evaluations of the three open source systems are compared with each other and also with the results from evaluations of three representative closed source systems: Staffware, WebSphere MQ and Oracle BPEL PM. The overall conclusion is that open source systems are targeted more toward developers rather than business analysts. They generally provide less support for the patterns than closed source systems, particularly with respect to the resource perspective, i.e. the various ways in which work is distributed amongst business users and managed through to completion.

Patterns-based Evaluation of Open Source BPM Systems: The Cases of jBPM, OpenWFE, and Enhydra Shark
- 2007

Rapport (övrigt vetenskapligt/konstnärligt)abstract
- The abundance of approaches towards business process specification and enactment is well-known and is an ongoing source of confusion. One of the objectives of the Workflow Patterns Initiative is to provide an insight into comparative strenghts and weaknesses of the state-of-the-art in Process Aware Information Systems. Over the past years many approaches to business process specification including commercial offerings, modelling languages, and academic prototypes have been evaluated in terms of the patterns in order to assess their capabilities in terms of expressing control-flow dependencies, data manipulation and resource allocation directives. With the increasing maturity and popularity of open source software it seems opportune to take a closer look at such offerings in the Business Process Management area. This report provides a patterns-based evaluation of three well-known open source workflow management systems: jBPM, OpenWFE, and Enhydra Shark.
