What is the purpose of a assumption sheet?

An assumption sheet is a document used to outline key assumptions made during project planning, analysis, or decision-making processes. Its purpose is to provide clarity and transparency regarding the underlying beliefs that guide the project's direction or financial model. By explicitly stating these assumptions, stakeholders can better understand potential risks, validate the feasibility of the project, and ensure alignment among team members. It also serves as a reference point for future evaluations and adjustments.
