Feasibility Study Report:

At the initiation of every large-scale project, it is customary to conduct a feasibility study to provide legal and technical evidence of the project’s viability, sustainability and cost-effectiveness. The reporting process allows the senior management to get the necessary information required for making key decisions on budgeting and investment planning. A well-written feasibility study report lets develop solutions for:

- Project Analysis because an example of FSR helps link project efficiency to budgeted costs.

- Risk Mitigation because it helps with contingency planning and risk treatment strategy development.

- Staff Training because the report can be used by senior management to identify staffing needs as well as acquire and train necessary specialists.

The process of reporting is the trigger to run the project investing process through underpinning the business case document, stating the reasons for undertaking the project, and analyzing project costs and benefits.

Detail Project Report:

Detailed Project Reports (DPRs) are the outputs of planning and design phase of a project. DPR is a very detailed and elaborate plan for a project indicating overall programmed, different roles and responsibilities, activities and resources required for the project.

To be more precise, A DPR is a final, detailed appraisal report on the project and a blue print for its execution and eventual operation. It provides details of the basic programmed the roles and responsibilities, all the activities to be carried out and the resources required and possible risk with recommended measure to counter them.

The success of project is measured on the basis of: -

- Whether the project was completed on time.

- Whether actual cost of project was within reasonable limits of escalation.

- Whether after completion of the project it was able to deliver the products of desired quality and in adequate quantity to client’s satisfaction at profitable costs.

- Whether the project gestation period was within planned duration.

The design stage is a blue print which on paper gives a great length and detail what has to be done to convert the corporate investment in a feasible project idea and ultimately a profit-making enterprise. The top management policy guidelines, its impact on the project life, appraisal in terms of financial viability is dealt in great detail. The DPR is the basic of specification, contract drawings, detailed technical feasibility, financial feasibility, execution of project from practical point of view. The DPR should also highlight the nature of inherent risks in the project & potential external risks that will influence the outcome of the project. Also, the DPR should give the measures for risk management and risk mitigation.

The main sub-division in a DPR is: -

- General Information of the project.

- Background and the experience of the project promoters.

- Details and working result of industrial concerns already owned and promoted by the project promoters.

- Details of the proposed project: -

Plant capacity

Manufacturing procedure adopted

Technical knowhow/ tie-ups.

Management teams for the project.

Details of land, buildings and plant and machinery.

Details of infrastructural facilities (power, water supply, transport facilities etc.)

Raw material requirement/ availability.

Effluents produced by the project & treatment procedures adopted.

Labor requirement and availability.

- Schedule of implement of the project.

- Project cost.

- Means of financial projects.

- Working capital requirement/arrangements made.

- Marketing and selling arrangement made.

- Profitability and cash flow estimates.

- Mode of repayment of loans.

- Government approvals. Local body consents and statutory permissions.

- Details of collaterals security that can offered to the financial institutions.
