This document presents a causal model of organizational performance and change developed by the authors based on their consulting experiences. The model depicts transformational and transactional factors that impact organizational performance. Transformational changes like shifts in mission and leadership directly impact transactional factors like structure, systems, and climate, which then impact motivation and performance. The authors cite theory and research to support the model's validity and discuss how it aims to provide a guide for organizational diagnosis and planned change by specifying causal relationships between key dimensions.
