I guarantee you, there is NOTHING that makes a sales person grin like a customer who comes back and says, we need to initiate a change order to our original specification. We used to bid our initial control systems so that they were indeed functional as specified, but it never failed that the customer suddenly remember that remote data collection unit somewhere east of nowhere that just HAD to be included in the scope of work. Oh, we were pretty fair about it. But unlike the initial contract where everyone sharpened their pencils, with change orders we could use crayons and didn't need to color inside the lines to make it pretty.
