In the COSO internal control framework, the Control Environment component serves as the foundation for the other components. It sets the tone of an organization, influencing the control consciousness of its people. It is the basis for all other components of internal control, providing discipline and structure. The control environment includes the integrity, ethical values, and competence of the entity's people; management's philosophy and operating style; the way management assigns authority and responsibility, and organizes and develops its people; and the attention and direction provided by the board of directors.
