Gallup has found that one of the most important decisions companies make is simply whom they name manager. Yet our analysis suggests that they usually get it wrong. In fact, Gallup finds that companies fail to choose the candidate with the right talent for the job 82% of the time.
Bad managers cost businesses billions of dollars each year, and having too many of them can bring down a company. The only defense against this massive problem is a good offense, because when companies get these decisions wrong, nothing fixes it.
