The manager of a large semiconductor production department expressed his disdain for the cost information he was presently given: Cost variances are useless to me. 2 I don’t want to ever have to look at a cost variance, monthly or weekly. Daily, I look at sales dollars, bookings, and on-time delivery (OTD)—the percent of orders on time. Weekly, I look at a variety of quality reports including the outgoing quality control report on items passing the final test before shipment to the customer, in-process quality, and yields. Yield is a good surrogate for cost and quality. Monthly, I do look at the financial reports. I look closely at my fixed expenses and compare these to the budgets, especially on discretionary items like travel and maintenance. I also watch headcount. But the financial systems still don’t tell me where I am wasting money. I expect that if I make operating improvements, costs should go down, but I don’t worry about the linkage too much. The organizational dynamics make it difficult to link cause and effect precisely.
