The ability to rapidly locate useful on-line services (e.g. software applications, software components, process models, or service organizations), as opposed to simply useful documents, is becoming increasingly critical in many domains. As the sheer number of such services increases it will become increasingly more important to provide tools that allow people (and software) to quickly find the services they need, while minimizing the burden for those who wish to list their services with these search engines. This can be viewed as a critical enabler of the ‘friction-free’ markets of the ‘new economy’. Current service retrieval technology is, however, seriously deficient in this regard. The information retrieval community has focused on the retrieval of documents, not services per se, and has as a result emphasized keyword-based approaches. Those approaches achieve fairly high recall but low precision. The software agents and distributed computing communities have developed simple ‘frame-based’ approaches for ‘matchmaking’ between tasks and on-line services increasing precision at the substantial cost of requiring all services to be modeled as frames and only supporting perfect matches. This paper proposes a novel, ontology-based approach that employs the characteristics of a process-taxonomy to increase recall without sacrificing precision and computational complexity of the service retrieval process.

In the past, most collaboration support systems have focused on either automating fixed work processes or simply supporting communication in ad-hoc processes. This results in systems that are usually inflexible and difficult to change or that provide no specific support to help users decide what to do next. This paper describes a new kind of tool that bridges the gap between these two approaches by flexibly supporting processes at many points along the spectrum: from highly specified to highly unspecified. The development of this approach was strongly based on social science theory about collaborative work.

A critical need for many organizations in the next century will be the ability to quickly develop innovative business processes to take advantage of rapidly changing technologies and markets. Current process design tools and methodologies, however, are very resource-intensive and provide little support for generating (as opposed to merely recording) new design alternatives. This paper describes the Process Recombinator, a novel tool for generating new business process ideas by recombining elements from a richly structured repository of knowledge about business processes. The key contribution of the work is the technical demonstration of how such a repository can be used to automatically generate a wide range of innovative process designs. We have also informally evaluated the Process Recombinator in several field studies, which are briefly described here as well.

Based on our experiences in the corporate banking department of the Union Bank of Switzerland we are convinced that business, IT and organizational aspects have to be considered in an integrated way while developing IT-strategies. IT-strategies are crucial for an effective (business) development because they identify the constant and the changing parts of an IT infrastructure during product life cycle. In order to achieve this, we state three design invariants: the deep structure of the process, the dependencies within the process, and the information handled. We believe that identifying these invariants will lead to a deeper understanding of product-life-cycles.

This article investigates how to support process enactment in highly flexible organizations. First it develops the requirements for such a support system. Then it proposes a prototype implementation, which offers its users the equivalent of a CAD/CAM-like tool for designing and supporting business processes. The tool enables end.users to take flexible building blocks of a production process, reassemble them to fit the specific needs of a particulr case and finally exports its description to process support systems like workflow management systems.

One of the key advantages of information technology is its ability to support new organizational forms. The task of shifting between old and new forms, however, can be a difficult, time consuming, and haphazard process (Davenport, 1993, Davenport and Stoddard, 1994; Hammer, 1990). Interactions among various work practices can lead to numerous unanticipated side effects as mangers alter individual practices without considering whole systems of work. In particular, the importance of complementarities among different practices has been formalized mathematically in the economic literature (Milgrom and Roberts, 1990). However, practicing managers and students have had difficult in applying these insights.

This paper provides a progress report on the development of software tools in the Process Handbook project currently underway at the MIT Center for Coordination Science. We begin with a brief overview of the project as a whole. Then we focus on software tools emphasizing aspects that relate to workflow control. Finally, we conclude with a brief description of future avenues of research. The process handbook tools help (a) redesign existing organizational processes, (b)invent new organizational processes that take advantage of information technologyand finally (c) automatical ly generate software to support organizational processes. An important related goal is the ability to (d) import and export process descriptions from and to other process modeling architectures. The approach combines in a novel way the ideas of process decomposition, process specialization, and the coordination of dependencies between activities. The paper presents an overview of findings from multiple implementations of this approach.
