The document defines a detailed project report (DPR) as a complete written report that provides details necessary for investment decisions, approval, and planning of a proposed business venture. A DPR goes beyond a prefeasibility study by covering maximum project details to help decision makers determine if a project should proceed. It identifies all commercial, technical, and entrepreneurial risks and includes information like market surveys, technology descriptions, resource evaluations, cost analyses, and implementation plans. The DPR serves as the base document for initiating, planning, implementing, and determining the costs of a new project.
