Reuse Economics Spreadsheet Model User Manual Version 01.00.00

Abstract

The Reuse Economics Spreadsheet Model tool implements various portions of the software reuse economics model described in (Cruickshank and Gaffney 1991). The model described in the report demonstrates the economic benefits of software reuse. You should be thoroughly familiar with this report to effectively use the tool. The Spreadsheet Model tool was designed to aid you in evaluating the impact of various reuse strategies on the costs of software products. The tool provides both spreadsheet and graphics capabilities. It requires the use of Microsoft Excel, version 3.0, and can operate on either a Macintosh or an IBM-compatible PC. The estimates of reuse costs, productivity, return on investment, and number of break-even systems implemented in the Reuse Economics Spreadsheet Model tool are just that-estimates. Mathematics cannot make estimates into certainties. It is very important for you, as the user of this tool, to note that the results of its application can be no better than the data it employs. If you do not have an accurate idea of how much it costs to create new code, how much it costs to reuse code, and how much it costs to invest in a reuse program, then the numbers that the tool generates will be correspondingly inaccurate.
