Terms of reference describe the purpose and structure of a project, committee, meeting, negotiation, or any similar collections of people who have agreed to work together to accomplish a shared goal. The terms of reference of a project are often referred to as the project charter. Terms of reference show how the object in question will be defined, developed, and verified. They should also provide a documented basis for making future decisions and for confirming or developing a common understanding of the scope among stakeholders. In order to meet these criteria, success factors/risks and constraints are fundamental. They are very important for project proposals.
