Critique the relevance of the systems model to the study of politics

Models, theories and concepts as approaches for analysing policy and decision making have been developed by political and social scientists to guide the study of public policy, to facilitate communication and to suggest possible explanations for policy actions.

A demand can be defined as a condition or situation that produces needs or dissatisfaction among people for which relief or redress is sought. For example problems such as air pollution, unwholesome food, abortion, urban congestion, crowded prisons and global warming are conditions that may become problems if they produce sufficient anxiety or dissatisfaction to cause people to seek a remedy. For this to happen people must have some criterion or standard by which the troubling condition is judged to be both unreasonable or unacceptable and appropriate for government to handle Anderson (1997). Conditions do not become public problems unless they are defined as such, articulated by someone or defined as such. The systems model therefore does not explore these highlighted problems.

According to Jackson & Jackson (ibid) the systems analysis is criticised often arguing that the model on which it is based does not help discern which part of a political system are essential or influential. It is further argued that it is impossible to predict how or even whether a change in one part of the system will affect another part. Furthermore political systems are not as closely related as the model implies. Political systems are not as static as the model implies
