Barnard's major contributions to the theory of organizations include: 1) Defining an organization as a social system requiring human cooperation to achieve consciously coordinated activities between two or more people. 2) Distinguishing between the formal and informal aspects of an organization, with the formal having better coordination and interaction and the informal having less coordination in social interactions. 3) Identifying key elements that organizations need like functionalization, incentives for group contributions, authority structures, and decision making powers to maintain equilibrium between individual and organizational efforts.
