Organizations frequently use product based organizational perf-ormance models to measure the effects of information system (IS) on their organizations. This paper introduces a complementary process based approach that is founded on measuring business process quality attributes. These quality attributes are defined on the basis of ISO/IEC 9126 Software Product Quality Model. The new process quality...
This paper aims at carrying out business process modelling and business process improvement using TAD methodology. The methodology consists of six phases; the first three deal with business process modelling and improvement, and the last three phases continue with the implementation of the improved business processes by developing an information system, which covers the areas discussed. To make the...
A popular requirement for the validation of workflow models is soundness. As soundness can not be easily seen on the model level, different correctness criteria have been proposed in the literature to bridge the gap between the modeling process and a executable workflow model. Well-structuredness and relaxed soundness are investigated in the paper. Relationships between the properties are derived.
The capability to easily find useful services becomes increasingly critical in several fields. In this paper we argue that, in many situations, the service discovery process should be based on both behavior specification (that is the process model which describes each composite service) and quality features of services. The idea behind is to develop matching techniques that operate on process models...
Recently, we have defined a formal semantics of Event driven Process Chains (EPCs) that, for the first time, faithfully captures the non-local behaviour of the XOR- and OR-join connectors. This fixed-point characterisation of the semantics of EPCs, however, does not provide an efficient algorithm for calculating the semantics of an EPC and for simulating it. In this paper, we will show how...
We present a framework for augmenting business process specifications with policy expressions such as obligations, permissions and prohibitions. One use of such a combined model is to support monitoring of participants’ behaviour against agreed policies as in business contracts.
As technology infrastructure becomes available for electronic exchange of contracts, the IT community is becoming more interested in modeling of contracts as governance structures for inter-organisational interactions and business processes. This paper investigates e-contract modeling and monitoring. Subsquently, we propose a contract layered model that allows for the convenient monitoring of multi-party...
BPM is considered as the suitable framework for today’s process-centric trends because it addresses the interplay of people and organizations on the one hand and process-aware software on the other hand. In such an environment, it is very important for each business participant to trace contents of total business processes. However, it has been a difficult problem for BPMS to support management of...
Current composite web service development and management solutions, e.g. BPEL, do not cater for developing adaptive business collaborations while adhering to the requirements imposed by the business environment. In this paper we introduce the Business Collaboration Design Framework which uses a blend of design perspectives, facets and aspects to provide designers with the means to develop and deliver...
The 20 workflow patterns proposed by Van der Aalst et al. provide a comprehensive benchmark for comparing control flow aspects of process modelling languages. In this paper, we present a novel class of Event-Driven Process Chains (EPCs) that is able to capture all of these patterns. This class is called “yet another” EPC as a tribute to YAWL that inspired this research. yEPCs extend EPCs by the introduction...
This contribution describes the results of a laboratory experiment which compares the Event-driven Process Chain (EPC) and Petri net (C/E net) regarding their approaches to represent the control-flow of processes. The outcome of the experiment indicates that from end-user perspective the EPC approach of applying connectors is superior to the token game. However, the non-local semantic of the EPC OR-connector...
In this paper, we present an approach to easily define flexible and reliable services compositions. We introduce a new concept called transactional patterns to specify flexible and reliable composite Web services. A transactional pattern is a convergence concept between workflow patterns and advanced transactional models. It can be seen as a coordination pattern and as a structured transaction. Thus,...
An enterprise process model encompasses a set of business processes implemented or to be implemented in the enterprise. As such, it expresses the requirements of the organization and thus constitutes a compulsory prerequisite for the successful implementation of process-based IT systems such as ERP, SCM and CRM. However, there is a lack of an enabling science to guide the generation of an individualized...
The majority of legacy information systems running today were built without adopting a business process approach. In these systems, the control over the execution of the process activities is partial, leaving out all those activities that have not been automated. Moreover, the activities that constitute the process are not formally interconnected, causing loss of the overall business process context...
In Workflow Management Systems (WFMSs), transaction isolation is managed most of the time by the underlying database system using ANSI SQL strategies. These strategies do not take sufficiently into account process aspects. Our work consists in studying with more depth the relation between isolation strategy and process dimension as well as the real isolation needs in workflow environments. To carry...
To configure a process-aware information system (e.g., a workflow system, an ERP system), a business model needs to be transformed into an executable process model. Due to similarities in these transformations for different companies, databases with reference models, such as ARIS for MySAP, have been developed. The models stored in such a database can be customized to generate an executable model...
