Surfacing embedded assumptions: Using repertory grid methodology to facilitate organizational change

This article outlines a 3-year research project that examines the role of performance evaluation and control systems in bringing about change in manufacturing organizations. A key aim of the project was to develop tools and techniques that managers can use to enable them to understand and enact change. As part of an indepth case study methodology, repertory grid interviews were used with both managers and operatives in three companies as a means of identifying commonly held assumptions about a range of work behaviours. The article discusses the use of the grid as a developmental, rather than exploratory technique, thereby focusing on its use as a process through which managers can assess their systems in use and highlight any necessary change issues. It is argued that repertory grid techniques have a useful part to play in diagnosing the key change issues that work and organizational psychologists face when planning organizational change and development interventions.
