Meaning of AGIL:
Introduced by Talcott Parsons, AGIL is the acronym for Adaptation, Goal attainment, Integration, and Latency. These according to Parsons are the four functional problems faced by any social system, whether big or small. Of these the first two are concerned with the relation of the system to the external environment, the other two are concerned with the internal condition of the system. Goal attainment involves the determination of goals and motivating and mobilising the members to attain those goals. Adaptation implies generating and acquiring resources from outside the system and to influence its distribution in the system. Integration means maintaining a level of solidarity and cohesion between the units of the system. Latency refers to storing, organising and maintaining the motivational energy of the components in the system through pattern maintenance and tension management. While pattern maintenance refers to the need to make sure that the actors are sufficiently motivated to perform their roles in the system or to maintain the value pattern, tension management focusses on the need for providing mechanisms for managing tensions of the members. The crucial point about the four system needs is that Parsons considers them to be the prerequisites for social equilibrium.
