Well, the rest of the story: As a contractor at Motorola (IRIDIUM), I watched my Motorola employee office mate and our common manager very carefully work out an estimate based on a project of similar complexity done about a year before I arrived, using the SLOC there as a major basis for the estimate. The result? The two level higher-up managers read the estimate workup, said, "Oh, you've done something like that before!?!" and cut the furnished estimate in half. Not even the best estimating tools and techniques will satisfy a manager with a preconceived deadline. xanthian. -- Posted via Mailgate.ORG Server - http://www.Mailgate.ORG
