“As part of the agreement announced Tuesday, AT&T will use Red Hat’s open-source platform to manage workloads and applications and “better serve” enterprise customers.”
Certainly they do. And the book admits as much. In my opinion, it is still a valuable read as it gives a generalized lens through which a large org’s structure, and activities at each layer, can be understood.
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.
