There are many stories that this phrase brings to mind, and this one comes from Bill Gusnard of Birmingham, Alabama:
In 1987, Bill was doing the mechanical engineering design for a small architectural firm in St. Louis. They had a client with retail stores (similar to Wal-Mart) and had previously designed six mid-level stand-alone stores for this client. When the request for bid was issued for another store, they bid on it, but it was awarded to another firm. Their contract with the storeowners allowed them to see copies of the competitor's drawings. When Bill looked over their drawings, he was amazed at what he saw. The winning bidder had copied all of his details on Stan-Pat and placed them on their drawings. Even more amazing, they had also copied all of the design down to the air handlers, chillers and other HVAC equipment as specified by Bill.
