Towards a Design Theory for Process-Based Knowledge Management Systems

In today’s knowledge economy, organizations need to effectively manage their knowledge to support an increasing number of knowledge intensive business processes. Such knowledgeintensive business processes could be more effectively supported by Process-based knowledge management (PKM) systems that integrate knowledge management services with process management systems. However, currently there are minimal design guidelines for developing such PKM systems. In this research-in-progress paper, we highlight this research problem, and propose a preliminary framework that can be extended to serve as a design theory for developing process-based knowledge management systems. Specifically, we identify kernel theories governing the design and development of PKM systems, and propose a design process for developing PKM systems. We also identify future research opportunities for further extending the framework and its evaluation

A design theory for requirements mining systems

Software requirements are often communicated in unstructured text documents, which need to be analyzed in order to identify and classify individual needs. This process is referred to as requirements mining in the context of this thesis. It is known to be time-consuming and error-prone when performed manually by a requirements engineer. Thus, there is a demand to support requirements mining through information technology. However, little research has been conducted to conceptualize theoretically grounded requirements mining systems and abstract the necessary design knowledge in a theory. Furthermore, existing works scarcely investigate the effect of these artifacts on requirements engineers’ productivity. Consequently in this thesis, the following research question is addressed: How can a system be designed which aims at improving requirements mining productivity over manual discovery? Following a Design Science approach, a design theory is derived consisting of design requirements, design principles and design features. Design requirements are identified based on general knowledge and kernel theories. Subsequently they are related to design principles which are finally mapped to design features of an artifact. The artifact is conceptualized in two design cycles, each resulting in a distinct artifact version and its evaluation. In the first design cycle a simulation is conducted to investigate the interplay of the preliminary design principles. In the second design cycle, the effects of the final design principles on requirements mining productivity are measured in an experiment. The thesis contributes to the design theory body of knowledge by providing a design theory for requirements mining systems. The theory is a contribution to the information systems literature because requirements mining systems represent an important class of design situations that have not been adequately described yet by existing works. From a practical point of view, the study addresses the need of requirements engineers to support their work by information technology and provides vendors of requirements engineering software packages guidelines to improve their products
