Jane spoke up once more. "But Stan, I already told you. The net present value and other analyses I did earlier show this plant would benefit from staying the way it is."Stan countered, "Jane, when you were working on the analyses, you said yourself that the benefits of auto-mation are hard to identify and assign numbers to. You had to make several assumptions in order to do those analyses. If you change some of your assumptions, you can make the numbers look better. Try a longer useful life for the new equipment, or change some of the pro-jected cost information. As soon as you have the new numbers, bring them to me to look at."
