What is the relationship between plan policy project and programme?

In project management, a "plan" outlines the strategy and approach for achieving specific goals, while "policy" refers to the guiding principles that dictate decision-making and action within an organization. A "project" is a temporary endeavor with a defined scope and objectives, typically aimed at producing a specific outcome. In contrast, a "programme" encompasses a group of related projects managed in a coordinated manner to achieve broader organizational objectives, aligning with both policy directives and strategic plans.
