Detailed project report is prepared for the investment decision-making approval, but also execution of the project and also preparation of the plan. Detailed project report is a complete document for investment decision-making, approval, planning. Detailed project report is base document for planning the project and implementing the project.
As the identification and intention for the implementation of the project grow, the depth of the study for the probable project increases. Further analyses of the details relevant to such a project become imperative.
We know that the feasibility report contains sufficient detailed information.It is from the study of the pre-feasibility or feasibility report that approval is made by the project owner (an individual or a project director/manager or the management of a company) for the investment on the project or for a request to prepare the DPR. Preparation of DPR is a costly and time-taking job (which may even extend to one year) when reports of specialists from different streams like market research, engineering (civil, mechanical, metallurgical, electrical, electronics), finance etc.—as relevant to the project itself—are considered in the DPR.
When the project is found definitely feasible, the DPR should stand with a background dealing with the recommendation for the project, as supported by the forecasted details for the coming years when the project is put into operation.
