This document describes the Holignment Organisation Maturity Model, which provides a framework for diagnosing and developing an organization's maturity. It involves 13 dynamics of development across 15 phases or levels of learning complexity. The model was created by integrating theories of learning and can measure how developed an organization is in different dimensions. It then provides a roadmap for guiding targeted interventions to systematically and sustainably improve the organization's functioning and move it to higher levels of maturity. The end goal is to help organizations achieve sustainable leadership and competitive advantage.
