On the basis of these characteristics, we can make out a comprehensive list of these characteristics:
(1) A set of elements or objects comprising a whole,
(2) Interactions and a regular pattern of interactions,
(5) Existence of boundaries,
(7) Functions performed by the Structures.
Almond is more interested in the study of processes than institutions. He tries a proper understanding of the structures within the political system through their functions. According to him, every political system has a set of structures which perform certain functions.
To quote Dr. S.P. Verma, “In fact, it is on the basis of the efficiency with which a political system performs the functions assigned to it as a political system that its stature in the scale of political development is determined.
Functions being given, the question that a political scientist may ask is: Through which mechanism are these functions being performed? In other words, one searches for structures by asking questions about functions.”
