One of the bloggers I follow asked what business books his readers found important. My first choice is Moneyball: The Art of Winning an Unfair Game by Michael Lewis. Yes, it's a book about running a baseball team, but its also a book about business.
What Moneyball really focuses on is the value that individuals bring to their organization. Lots of talented people are undervalued by their organizations because they are not flashy or do the high profile work, but their efforts bring greater value to the company, dollar for dollar, hour for hour, that the best paid staff.
Your organization is probably overpaying for the flashy help, too. Dump them and cherry pick two undervalued staff from the shop down the street.
