Public policy implementation and programs are shaped by various factors including expertise, leadership, politics, and budgets. Programs operationalize public policy goals to address societal problems. The policymaking process involves legislative development of policies, administrative implementation through rulemaking and programs, and judicial/legislative review. Effective implementation requires planning, interpretation of legislative intent, and application of programs. Evaluation determines program success through data collection and analysis methods like before/after studies and controlled experiments. Evaluation results inform continuation, termination, or changes to policy and future planning.
