Design Science in Research Cooperations with the Industry: Findings from three Prototyping Projects
In: forthcoming in: DESRIST 2010: 5th International Conference on Design Science Research in Information Systems and Technology; St. Gallen, Switzerland
Category: Proceedings
AbstractA challenge that IS researchers face in general is to combine the goals of generating new scientific knowledge while at the same time producing practically relevant research results, e.g., in the form of IT artefacts. To combine rigor and relevance, researchers and practitioners need to collaborate to develop and employ methods that enable both the systematic generation of scientific insights and the knowledge exchange between academia and practice. In this paper, we present the findings of a research project where we entered into an industry-academic collaboration with the financial services industry involving three software development and implementation projects. We adopted a design science research approach to accompany the industry-academic project and to guide the scientific discovery process. In the course of our research process we developed an innovative research model that integrates our experiences from the research project with existing design science research models.

Assessing Project Effort in Requirements Engineering: A Report on Design Research in Progress
In: forthcoming in: DESRIST 2010: 5th International Conference on Design Science Research in Information Systems and Technology; St. Gallen, Switzerland
Category: Proceedings
AbstractIn this paper we report on our design research in progress, where we have developed an artifact that assesses project effort resulting from requirements. Based on models used in the goal-oriented requirements engineering method KAOS, the artifact measures system size via function point analysis and analyzes system complexity via structural analysis. In addition, we provide theoretical explanations and empirically validate how size and structural complexity affect project effort. Overall effort depends on counted functions that must be transformed, since software development can be regarded as a transformation process where size matters. Structural complexity matters as well, since software development is also a complex problem, where effort spent depends on the structure of the problem. Insights from empirical evaluation in three software development projects are encouraging, wherefore we believe that the artifact appropriately assesses project effort. Furthermore, our artifact increases the utility of KAOS by providing additional information on project effort.

Mapping Model for Assessing Project Effort in Requirements Engineering
In: forthcoming in: Business & Information Systems Engineering
Category: Publications in scientific journals
AbstractProject effort is critical for the success of software development projects. It has a major impact on whether constraints in time and budget can be complied with. But although requirements affect project effort, requirements engineering (RE) methods are not capable of assessing project effort.
In this paper, we present our mapping model for assessing project effort (MMAPE). MMAPE incorporates into RE the assessment of project effort resulting from requirements for software development projects. It maps semantics of the RE method KAOS onto structures that are counted in function point analyses. We applied MMAPE in a case study on a software development project within a large financial institution. The validity of MMAPE is supported, since we found throughout consistent statements between information provided by MMAPE and data gathered from the case.

Psychological Contract Violation in IT Megaprojects in the Context of Public Private Partnerships – The German TollCollect Case
In: Proceedings of the 18th European Conference on Information System (ECIS 2010); Pretoria, South Africa
Category: Proceedings
AbstractPrior research in the context of public private partnerships has mainly focused on organizational and risk management aspects. Because there is a growing number of IT megaprojects in the context of public private partnerships, recent work concentrates on the explanation of the relationship between public and private partners and the success factors for these relations. However, we still have a lack of understanding on the causes and consequences for IT megaproject failure in the context of public private partnerships. In this exploratory, qualitative single-case study from the German TollCollect IT megaproject we draw on findings from the psychological contract theory to explain psychological contract violation as a threat to IT megaproject success. Our research model suggests that the management of common understanding and expectations, moderated by political and public pressure of a public-private environment, affects the stability of the psychological contract and therefore the success of an IT megaproject in the context of public private partnerships.

Conflict as Manifestation of Culture in Global IS Outsourcing Relationships
In: Proceedings of the 18th European Conference on Information System (ECIS 2010); Pretoria, South Africa
Category: Proceedings
AbstractThe objective of this paper is to propose a new way of analyzing culture in global IS outsourcing relationships. Previous research in IS has focused on the analysis of values, beliefs, customs, and other elements of culture whereas other inherent characteristics of culture, such as its dynamic and subjective nature, have been widely ignored. Hence, we suggest analyzing culture and identity in relation to action thereby accounting in more detail for the above mentioned characteristics. In particular, we develop a conceptual model describing the relationship between social identity and conflict in global IS outsourcing relationships. Propositions are derived from social identity and inter-personal conflict theory. The concept of cognitive flexibility (derived from cultural intelligence theory) is introduced as a moderator variable, influencing the relationship between social identity and inter-personal conflict. The conceptual model developed in this paper makes a theoretical contribution to the global IS outsourcing domain and serves as a basis for future empirical research.
