Highly recommend the book “The Leadership Pipeline” written by Ram Charan. The book focuses on developing a pipeline through which leaders within an organization move and describes accountabilities at each level, along with red flags that indicate that a manager at a given level isn’t operating correctly at said level. Very helpful in understanding what happens (or should be happening) at each level.

Ram Charan is a well respected author and consultant, who has according to Wikipedia consulted with some of the largest businesses in the US.
