Marketing won't speak to engineering. Sales thinks production hogs the budget. Front desk believes back room's lazy. These sorts of turf wars, which turn outwardly unified companies into groupings of uncommunicative "silos," are the stuff of management lore. According to bestselling author Lencioni (The Five Dysfunctions of a Team), "they waste resources, kill productivity and jeopardize the achievement of goals"they also drive workers into tizzies of frustration. Like his previous books, Lencioni's latest addresses the management problem through a fictional story; this one revolves around a self-employed consultant named Jude, who has to dismantle silos at an upscale hotel, a technology company and a hospital. Split into two sections, Lencioni's book first shows Jude discovering a solution to silos, then summarizes Jude's lessons into a strategy that readers can apply to any business. Lencioni's proposal is so full of common sensenamely, end turf wars by getting departments to rally around a common goalthat managers will be eager to apply it themselves. Just as refreshing is Lencioni's use of character and plot, which is far above average for the business genre. As sympathetic as Jude is, he makes Lencioni's management lessons memorable.
