The expected prediction result is as follows:
4.2 Scenario: Analyze the Cash Flow of an Investment on a
New Product
We wish to do an analysis of the cash flow of an investment required to create a new product. Projected
estimates are given for the product revenue, product costs, overheads, and capital investment for each year of
the analysis, from which the cash flow can be calculated. For capital investment appraisal the cash flows are
summed for each year and discounted for future values, in other words the net present value of the cash flow
is derived as a single value measuring the benefit of the investment.
