The Quality Management Maturity Grid (QMMG) outlines 5 levels of maturity for organizations: Uncertainty, Awakening, Enlightenment, Wisdom, and Certainty.

Crosby's model advocated the principles of doing it right the first time to eliminate defects and lower costs of quality programs through a zero defects approach.
