Great article, I have I seen this situation too many times to count. It isn't just consultants that generate haunted graveyards. Any person will skills more advanced than their peers will do so. To make matters worse it isn't just the peers you have right now but the peers you will have in the future who you don't currently know and can't predict their skill level.

While the solutions you list can help, it will not solve the haunted graveyard problem, just ask all of the companies with Cobol programs in production.
