Summary of theory Policymaking is characterised by the interaction of advocacy coalitions within a policy system. Belief systems guide choices and actions. Alignment and activity of coalitions can drive change. Policymaking is composed of three streams: problem; policy: and politics. When these streams come together during open policy windows, policy change is likely to occur. Policy entrepreneurs play a crucial role in this process. Policymaking is characterised by long periods of incremental change punctuated by brief periods of major change. Policy image (framing) and public mobilisation play a central role in aiding policy change. Possession of links to actors beyond one’s immediate close knit cluster can greatly increase opportunities for new or distinct information. Access to this information can provide new insights enabling advocates to better influence policymaking.
