Purpose: This paper aims to explore the use of developmental evaluation methods with community of practice programmes experiencing change or transition to better understand how to target support resources. Design/methodology/approach: The practical use of a number of developmental evaluation methods was explored in three organizations over a nine-month period using an action research design. The research was a collaborative process involving all the company participants and the academic (the author) with the intention of developing the practices of the participants as well as contributing to scholarship. Findings: The developmental evaluation activities achieved the objectives of the knowledge managers concerned: they developed a better understanding of the contribution and performance of their communities of practice, allowing support resources to be better targeted. Three methods (fundamental evaluative thinking, actual-ideal comparative method and focus on strengths and assets) were found to be useful. Cross-case analysis led to the proposition that developmental evaluation methods act as a structural mechanism that develops the discourse of the organization in ways that enhance the climate for learning, potentially helping develop a learning organization. Practical implications: Developmental evaluation methods add to the options available to evaluate community of practice programmes. These supplement the commonly used activity indicators and impact story methods. Originality/value: Developmental evaluation methods are often used in social change initiatives, informing public policy and funding decisions. The contribution here is to extend their use to organizational community of practice programmes.
