I can't tell you how many times I've seen it. I know of one director, a couple of senior managers, and one "chief of staff." Go ahead, laugh, it's really his title. And each of them got the jobs that they have because "something" would be left out of an implementation on golive, then they would "find" the error, permission change, version mismatch, etc. etc. and they would be the hero.

In one case, I was project lead over system integration for a merger that went without a hiccup, while I was on vacation, with validations done by my backup from the documentation I wrote up. What did I get? An email saying, "Lucky that nothing happened while you were out."

Said Director however did a "nothing" upgrade to the Point of Sale systems causing a nationwide outage for a little over an hour, and when he "found" the max number of threads to the database was too low, he was given a "key contributor" bonus and his promotion to his current level of Director.

Your collegues might know the difference, but the people on the business side will definitely see you as their "hero" and guess who signs the checks?
