The document discusses different frameworks for understanding decision-making in the policy process. It describes rational decision-making, the garbage can model, bounded rationality, incrementalism, and the multiple streams framework. It notes that rational decision-making assumes all factors are known, while real-world policy decisions often have ambiguous problems, options, and criteria. The garbage can model sees problems and solutions floating independently. Bounded rationality recognizes limits in knowledge. Incrementalism bases decisions on past formulations. The multiple streams framework sees problems, policies, and politics interacting. The document concludes with a definition and advantage of collaborative governance.
