A more thorough explanation:

A policy is a set of rules or principles that guide a government or organization in making decisions and taking action. It helps them to govern effectively and achieve their goals.

For example, a school might have a policy that all students must wear uniforms. This rule guides the school in maintaining a certain level of discipline and professionalism among its students.

Another example is a government policy to reduce carbon emissions. This policy guides the government in taking action to address climate change and protect the environment.

Policymaking is a process that involves identifying a problem, setting goals, making decisions, and evaluating the results. It is an ongoing cycle that helps organizations and governments to adapt to changing circumstances and achieve their objectives.
