Integrating Software Engineering and Usability Engineering

ion. While this can lead to successful results, it fails to provide a continuous strategy for integration that considers the structural, organizational and operational aspects on equal footing and is adaptable to a variety of established and evolving SE practices. This has been illustrated by the advent of so called agile development approaches that have become popular in recent years, resulting in the need for newly adapted strategies for UE integration. In the following sections we introduce a systematic approach that covers the three levels of abstraction from standards over process models to operational processes to address this challenge in a systematic way. 5. Integration on three Levels of Abstraction In order to identify integration points between the two disciplines examination and analysis has to be performed on each level of the abstraction hierarchy: On the most abstract level of standards it has to be shown that the central aspects of SE and UE can coexist and can be integrated. On the level of process models it has to be analyzed how UE aspects can be
