Following D. KATZ and R.L. KAHN (1966) the five basic classes of systemic functions are:
- Production: i.e. transformation of the inputs into products or services, characteristic of the system;
- Maintenance: i.e. obtaining from the environment the inputs needed to maintain the activities of the system;
- Manutention: maintaining the systems internal coherence;
- Adaptation: production of the changes needed to allow the system's survival in its environment;
- Direction: coordination of the activities of all the subsystems and designing goals and means to achieve them.
