The document describes Richard Barrett's Seven Levels of Consciousness model, which extends Abraham Maslow's Hierarchy of Needs to understand individual and group consciousness development. The model includes both internal dimensions like self-knowledge and external dimensions like expanding one's sense of identity. Barrett developed tools like the Cultural Transformation Tools to map organizational values and leaders' levels of consciousness using this model. The document also outlines applications of the model for individuals, groups, decision-making, and building values-driven cultures.
