Can Patterns improve Modeling? Two Exploratory Studies

International Working Conference on Requirements Engineering: Foundations for Software Quality (REFSQ'08), co-located with CAISE'08, Montpellier, France, 2008, 2008

A considerable amount of effort has been placed into the investigation of i* modeling as a tool for early stage requirements engineering. However, widespread adoption of i* models in the requirements process has been hindered by issues such as the effort required to create the models, coverage of the problem context, and model complexity. In this work, we explore the feasibility of pattern application to address these issues. To this end, we perform both an exploratory case study and initial experiment to investigate whether the application of patterns improves aspects of i* modeling. Furthermore, we develop a methodology which guides the adoption of patterns for i* modeling. Our findings suggest that applying model patterns can increase model coverage, but increases complexity, and may increase modeling effort depending on the experience of the modeler. Our conclusions indicate situations where pattern application to i* models may be beneficial.

Analyzing Knowledge Transfer Effectiveness - An Agent-Oriented Approach

n Proceedings of the 40th Hawaii International Conference on System Sciences (HICSS-40 2007), January 3-9, IEEE Computer Society, Hawaii, USA, 2007., 2007

Facilitating the transfer of knowledge between knowledge workers represents one of the main challenges of knowledge management. Knowledge transfer instruments, such as the experience factory concept, represent means for facilitating knowledge transfer in organizations. As past research has shown, effectiveness of knowledge transfer instruments strongly depends on their situational context, on the stakeholders involved in knowledge transfer, and on their acceptance, motivation and goals. In this paper, we introduce an agent-oriented modeling approach for analyzing the effectiveness of knowledge transfer instruments in the light of (potentially conflicting) stakeholders ’ goals. We apply this intentional approach to the experience factory concept and analyze under which conditions it can fail, and how adaptations to the Experience Factory can be explored in a structured way.
