The extended process model - transforming process specifications into ontological representations

2006 , Brocks, H. , Meyer, H. , Kamps, T. , Begger, C.

Knowledge-intensive processes arc often open ended and can be only weakly specified in traditional business process models. The extended process model provides a comprehensive integration of process and knowledge specific aspects within a single, ontological representation. In this article we describe the transformation of standardized business process definitions into a unified conceptual process model. We then apply our methodology to the scenario of IT services.

Facilitating asynchronous discussions in learning communities: the impact of moderation strategies

2007 , Kienle, A. , Ritterskamp, C.

A facilitator or moderator is often responsible for supporting processes and their progress in learning communities. In this article we present an approach for supporting moderators of asynchronous processes in learning communities. This approach follows the socio-technical perspective: it includes a theory-based development of moderator tasks and the technical features designed to support these tasks. Starting with relevant work in this area, we describe our approach to moderator support in the collaborative learning environment KOLUMBUS 2. In a qualitative study, a professional moderator facilitated the discussion processes of a group of 12 students based on KOLUMBUS 2. The moderator used different methods and varying levels of participation intervention. The study showed that different intervention strategies led to different levels of student participation and different successes in finding common results at the end of the discussions. Suggestions for the design of technical features are also made.

A multiagent environment for the flexible enactment of knowledge-intensive processes

2006 , Bayer, K. , Kempf, S. , Brocks, H. , Kamps, T.

Knowledge-intensive processes are characterized by vague specifications and a dynamic course of action. They require a flexible, knowledge-based enactment environment supporting the dynamic allocation of resources, changes in assignments, organizational structure, policies, and requirement and priorities, but also conflicts between resources participating in different processes. In this article, we present a multiagent enactment environment that incorporates the flexible allocation of resources but is also capable of handling various types of runtime exceptions. The benefits of adopting a knowledge-based approach are demonstrated based on a prototype implementation of an IT-Helpdesk scenario.

Modeling architectural patterns using architectural primitives

2005 , Zdun, U. , Avgeriou, P.

Architectural patterns are a key point in architectural documentation. Regrettably, there is poor support for modeling architectural patterns, because the pattern elements are not directly matched by elements in modeling languages, and, at the same time, patterns support an inherent variability that is hard to model using a single modeling solution. This paper proposes tackling this problem by finding and representing architectural primitives, as the participants in the solutions that patterns convey. In particular, we examine a number of architectural patterns to discover those primitive abstractions that are common among the patterns, and at the same time demonstrate a degree of variability in each pattern. These abstractions belong in the components and connectors architectural view, though more abstractions can be found in other views. We have selected UML 2 as the language for representing these primitive abstractions as extensions of the standard UML elements. The added value of this approach is twofold: it proposes a generic and extensible approach for modeling architectural patterns by means of architectural primitives; it demonstrates an initial set of primitives that participate in several well-known architectural patterns.
