Theory And Practice Of Post-Installation Appraisals Of Projects

Throughout the mining industry, many companies perform sophisticated business and financial analyses of proposed capital investments. However, once the project is approved, it is never reevaluated. At best, there is an attempt to control capital costs and minimize overruns. The post-installation appraisal, a formalized review of investment performance, may prove helpful. Typical Project Review A typical capital investment is approved after business and financial benefits have been reviewed with management.* The financial data shown to management often include a net income statement, cash flow analysis and summary economic data similar to those shown in Table 1 overleaf. These financials report the expected impact of the project on the corporation financial statements. This project is a rudimentary example of a capital investment decision. An actual project would undergo a more sophisticated analysis incorporating depletion benefits, deferred taxes and a detailed cost breakdown. The example project has several financial benefits that could result in management approval. For example, it provides an immediate net income benefit to the company, generates positive cash flows every year of the project life and has a discounted cash flow rate of return of 25 percent. However, it also has the disadvantage of a long payback period. A sensitivity analysis would show which areas of the analysis have the greatest impacts on profitability. Post-Installation Program Objectives The post-installation appraisal goes beyond the analysis shown in Table 1 by comparing actual results to those projected in the original economic analysis. The post-installation program has three primary objectives: 1. To provide a periodic performance review of major spending programs. 2. To review decision-making and evaluation procedures. 3. To provide a means of controlling individual project investments. The first major function of the post-installation program is the periodic review of actual performance of projects and investment programs, identifying those factors which proved critical to the health of investments. This review will serve to keep management abreast of progress, provide a comparison of actual performance against expectations, and provide valuable information that can be used for improving future economics. The second major function of the program is to perform a continuous review of the decision-making process. This includes testing of evaluation procedures, forecasting techniques, and logic used in making decisions. An information system should be set up whereby original evaluations and historical performance data gathered under the appraisal program are documented for use by evaluators and management when assessing past and future investment proposals. Such data should be particularly useful in evaluating new and developing types of operations and in activities where companies repeatedly reinvest. The primary purpose of this feedback system is to sharpen estimates to assure that they are realistic and attainable. The appraisal program also provides assurance that consistent evaluation procedures are being used throughout a company, leading to improved procedures
