Abstract
A case study of a business-focused evaluation model is presented. This was developed as part of an organizational development intervention for Zetex plc, a global semi-conductor company. The value of the model is assessed against three principles (concerning collaboration, joint ownership and integration) drawn from client and provider needs and from current thinking in evaluation research. Findings from the study highlight benefits to the company and participants, and provide significant learning for future use and development of the model.
