Final answer:
Policy development entails the process of creating and implementing public policies through stages like agenda setting, policy enactment, implementation, and evaluation.
Step-by-step explanation:
Policy development refers to the process of creating and implementing public policies. It involves several stages, including agenda setting, policy enactment, policy implementation, and evaluation.
During the agenda setting stage, issues are identified and prioritized. Then, policies are enacted through legislation or other means. After that, the policies are put into practice, and their outcomes are evaluated to assess their effectiveness.
For example, in the case of healthcare reform, policy development involved years of analysis, debate, and refinement, and even trial implementation at the state level before the final policy was implemented.
