BUSINESS-IT ALIGNMENT FROM A VALUE-BASED PERSPECTIVE

This presentation, which has been delivered at SIREN2006, provides our position on business-IT alignment: a more engineering-oriented approach is needed. We show how this can be accomplished by using value-based modeling, in particular as provided by e3value.

BUSINESS-IT ALIGNMENT

Business-IT alignment is the "continuous process ... of interrelating all components of the business-IT relationship in order to contribute to the organization's performance over time" (Maes et al., 2000). This presentation, delivered at the SIKS course on architectures for information and knowledge-based systems, presents several approaches for modeling the alignment phenomenon, and pays attention to the intricate problem of validating such models.

GOAL-ORIENTED REQUIREMENTS ENGINEERING FOR E-SERVICES

The current dominant approach in requirements engineering is goal-oriented requirements engineering (for a very good overview, see the slides of John Mylopoulos' keynote address at RE'06). In this presentation, we present our ideas on how goal-oriented RE can be combined with value modeling, a proven technique for developing services delivered via electronic channels.

This presentation was delivered by Jaap Gordijn at the International Workshop in Service-oriented Requirements Engineering, Kyoto, Japan, September 6, 2004, in conjunction with RE'04. The paper published in the workshop proceedings is available here.

JACKSON'S PROBLEM FRAMES AND GORDIJN'S VALUE MODELS COMBINED

Michael Jackson's problem frames approach is a good tool to understand the boundaries of a problem and how a problem relates to assumptions about its context. Most of the examples in Jackson's excellent book are about, let's say, traditional software systems and embedded systems. In the paper we presented at the 1st International Workshop on Advances and Applications of Problem Frames, we investigate if Jackson's approach can be applied to e-services as well. Roel Wieringa presented our results at the workshop using these slides.
