1. Explain the view that the social system is a basic conceptual model useful in understanding social organization.

Social system and social organisation are two separate concept of sociology, but social system yet acts as the building block of the social organisation. To understand this we first need to understand the attributes of the social system

1. System is unified: Anything viewed as system must be viewed holistically. It is made up of parts called subsystem
2. System is structured: There is a stable pattern of relationship between parts of system. They link in definite and predictable ways
3. A system has goal
4. System has boundary, beyond which the external environment exists
5. System exists in symbiotic interdependence with the environment
6. System has equilibrium tendency: System tries to maintain the equilibrium, with every change, the system again tries to achieve the new equilibrium. It also has internal process of adjustment

Social organisation refers to a pattern of social interaction. Expectations from actors becomes fixed. Actors agree to control themselves on important matters to cooperate. Thus they involve interaction.

Starting from dyads, primary, informal to formal organisation. Each one of them show the characteristics of system, infact the system acts as system built inside the organisation. The organisation is having goals, a structure, existing with external environment and tries to achieve equilibrium with every change. They also need to have the symbiotic relationship with the external environment to exist. For example any organisation can't exist for long without having symbiotic relation with political, sociological, technological etc.
