What is the difference between a concept note and a project proposal?

A concept note is a brief document that outlines the main ideas and objectives of a project, serving as an initial pitch to gauge interest or secure preliminary funding. In contrast, a project proposal is a more detailed plan that includes specific methodologies, timelines, budgets, and evaluation strategies, aimed at securing formal approval and funding. Essentially, the concept note provides a high-level overview, while the project proposal delves into the operational specifics required for implementation.
