Out of all the things we expect of leaders — taking charge, setting strategy, empowering people, driving execution, you name it — what one single behavior would you guess is most often neglected or avoided among executives? Seeing the big picture? Nope. Delegating? Nope. Mapping out detailed project plans? Nope. Although many upper-level managers don’t do these things enough, by far and away the single-most shirked responsibility of executives is holding people accountable. No matter how tough a game they may talk about performance, when it comes to holding people’s feet to the fire, leaders step back from the heat.
