This document introduces the Holignment Organisation Maturity Model, which provides a framework for assessing an organization's maturity across 13 dynamics and 15 phases of development. The model was developed by examining theories of learning and organizing them into hierarchical levels of increasing complexity. It offers a diagnostic tool to measure where an organization is functioning across different dimensions and provides a development path to guide interventions and sustainable growth. Applying the model provides a baseline, benchmarks progress, and aligns change efforts with business strategy to transform an organization in a systematic, engaged process.
