In 1996, I worked on three software packages for mutual fund titan T. Rowe Price of Baltimore. NSCAD alumni David Peters, who managed the three projects—Retirement Savings Analyzer, Decisions (401k), and a third for track IRAs—saw the project through the lens of the user. David recognized there might have been TRP investors who would use all three. This approach told us one thing: no matter what application, the results (output) had to be the same if the input was consistent among all three. If not, it could be a catastrophic failure for the investment firm. Thus, all three software applications—that fit on a single floppy disc—use the same calculation engine.
