TL;DR: The Matrix of Change as discussed by the authors is a change process reengineering tool that helps managers identify critical interactions among processes and deal with issues such as how quickly change should proceed, the order in which changes should take place, whether to start at a new site, and whether the proposed systems are stable and coherent.
Abstract: Business process reengineering efforts suffer from low success rates, due in part to a lack of tools for managing the change process. The Matrix of Change can help managers identify critical interactions among processes. In particular, this tool helps managers deal with issues such as how quickly change should proceed, the order in which changes should take place, whether to start at a new site, and whether the proposed systems are stable and coherent. When applied at a medical products manufacturer, the Matrix of Change provided unique and useful guidelines for change management.

TL;DR: An overview of the prevailing approaches to design a business process architecture is provided, which showed that practitioners have a preference for using approaches that are based on reference models and approaches that is based on the identification of business functions or business objects.
Abstract: With the uptake of business process modelling in practice, the demand grows for guidelines that lead to consistent and integrated collections of process models. The notion of a business process architecture has been explicitly proposed to address this. This paper provides an overview of the prevailing approaches to design a business process architecture. Furthermore, it includes evaluations of the usability and use of the identified approaches. Finally, it presents a framework for business process architecture design that can be used to develop a concrete architecture. The use and usability were evaluated in two ways. First, a survey was conducted among 39 practitioners, in which the opinion of the practitioners on the use and usefulness of the approaches was evaluated. Second, four case studies were conducted, in which process architectures from practice were analysed to determine the approaches or elements of approaches that were used in their design. Both evaluations showed that practitioners have a preference for using approaches that are based on reference models and approaches that are based on the identification of business functions or business objects. At the same time, the evaluations showed that practitioners use these approaches in combination, rather than selecting a single approach.

TL;DR: By incorporating better resource characterizations in contemporary tools, business process simulation can finally deliver on its outstanding promise and solve several additional and more fundamental problems.
Abstract: Although simulation is typically considered as relevant and highly applicable, in reality the use of simulation is limited. Many organizations have tried to use simulation to analyze their business processes at some stage. However, few are using simulation in a structured and effective manner. This may be caused by a lack of training and limitations of existing tools, but in this paper we will argue that there are also several additional and more fundamental problems. First of all, the focus is mainly on design while managers would also like to use simulation for operational decision making (solving the concrete problem at hand rather than some abstract future problem). Second, there is limited support for using existing artifacts such as historical data and workflow schemas. Third, the behavior of resources is modeled in a rather naive manner. This paper focuses on the latter problem. It proposes a new way of characterizing resource availability. The ideas are described and analyzed using CPN Tools. Experiments show that it is indeed possible to capture human behavior in business processes in a much better way. By incorporating better resource characterizations in contemporary tools, business process simulation can finally deliver on its outstanding promise.

TL;DR: The authors describe a method for integrating separately developed information models that provide a coherent picture of an enterprise and enable its resources to be accessed and modified coherently.
Abstract: The authors describe a method for integrating separately developed information models. The models may be the schemas of databases, frame systems of knowledge bases, domain models of business environments, or process models of business operations. The method achieves integration at a semantic level by using an existing global ontology to develop semantic mappings among resources and resolve inconsistencies. The method is incorporated in a graphical integration tool. The integrated models provide a coherent picture of an enterprise and enable its resources to be accessed and modified coherently. >
