Deleting down to the bare bones, an 18 page ladder schematic that was in the Vault "Approved for Construction"..... because the engineer made so many changes that it was unrecognizable, and starting from scratch was really the only alternative. 40 hours or more down the hole, and another 40 that I do not have to do it over.
This is NOT happiness.
It's the Approved that gets me.... why the #*&^$!! did he approve it if it was THAT wrong? I see this behavior far too often around here.
Intertia. That, and it means his schedule isn't showing the impact (but yours is) aka "I'm not the one holding up the schedule!". Time to break out the change management documentation. Sometimes the mere threat of extra paperwork is enough to keep the change hounds at bay.
