In April, just nine months after a Business 2.0 cover story trumpets the wisdom of Raytheon CEO William Swanson and his folksy hit book, Swanson's Unwritten Rules of Management, a San Diego engineer makes a shocking discovery: 17 of Swanson's 33 rules are similar - and in some cases identical - to those in The Unwritten Rules of Engineering, a 1944 text by UCLA professor W.J. King.

While conceding that he failed to give proper credit, Swanson insists he didn't intend to plagiarize, suggesting that old photocopied material may have wound up in his "scraps."

By way of punishment, Raytheon's board freezes Swanson's salary at its 2005 level of $1.1 million and cuts his restricted stock grant by 20 percent.
