||The overall research, presented in multiple parts, discusses success factors as well as potential pitfalls regarding the contents and processes of designing and implementing modern office work environments in Germany. A holistic concept to effectively evaluate workspace change projects has been developed in part 1. This evaluation concept covered two areas: The major dimensions of workspace design including involved actors and performance parameters, and the processes of implementation the change management aspects. The interaction of these areas was also considered. Part 2 of the research, which is presented here, applies, tests and modifies the evaluation approach for workspace change projects suggested in part 1. For that, a comprehensive case study of a German financial services organization is used. The case study spans the time frame from preparing the change, the move into the new office environment, and 14 months thereafter. It uses a mixed methods approach with document research, several series of mostly half structured interviews, weekly web surveys and corresponding project team meetings. A comprehensive final survey covers the contents as well as the change management processes of the workspace project. The results of the evaluation are presented and discussed in a workshop including the project team and user representatives. With the integration of this information, the concept and the evaluation approach are adapted, resulting in a framework that can be used as a guideline to performance-oriented design, implementation, and evaluation of new work environments.
