Often the actual dollar cost of buying a new system seems lower to just get a whole new system wholesale the added costs associated with overhead, allocated costs, and especially depreciation make this hot new deal not really worth the nominal dollar savings. To do a proper analysis, from an accounting (actually more properly from a financial perspective) requires a break even analysis that incorporates the expected life of the old machine and the replacement costs of the new machine. This is a typical exercise in capital budgeting. It is rarely worth the effort to do this kind of analysis on less than an entire complement of machines (i.e. at least $100,00 min) because of the factored overhead of using the financial and computational resources to do this analysis. Just like in the world of computing where systems analysis and design is one method of determining the resources required to perform a programming schedule, capital budgeting requires a rather sophisticated decision analysis and b-tree like extrapolation of costs and probabilities. Now once all this information is collected then a computer program can chunk it out in a rather short period of time. AS a person who sits right smack in the middle of all three camps (computing, accounting, and finance) I have found that computing services, in general, does not even grasp the financial perspective -- but then of course I feel that most accountants don't either but that's another story. :-) Kevin -- Kevin "auric" Crocker Athabasca University UUCP: ...!{alberta,ncc,attvcr}!atha!kevinc Inet: kevinc@cs.AthabascaU.CA
