As an employee, you function mostly as a solitary unit. You do your part, produce your "output," and the work is done. But as a manager (or more precisely, a leader—managers manage tasks, leaders lead people), everything changes. Your success is no longer about your own output, it's about other people's -- the most important work you do is often what enables other people to do their jobs. But finding your way can be difficult. So in honor of National Book Month, here are three books that every leader should read to succeed.
High Output Management by Andy Grove
Key points: Grove's book, reflecting on his time as Intel CEO in the 1970s, remains relevant today because of the basic principles it outlines: As a leader, you are an enabler of others. Your team's performance, not your own output, is what you are judged on. Grove also shares five key things that should inform and govern your time: decision making, information gathering, information sharing, nudging and role modeling. If you are spending significant time doing things outside of those five key areas, it might be worth rethinking your schedule.
Best quote: "The art of management lies in the capacity to select from the many activities of seemingly comparable significance the one or two or three that provide leverage well beyond the others and concentrate on them."
Who Says Elephants Can't Dance? Inside IBM's Historic Turnaround by Lou Gerstner
Key points: Compared to High Output Management, which can read a little like a textbook, Who Says Elephants Can't Dance? is practically a thriller. Gerstner's well-known memoir about the turnaround of IBM is a vibrant book on leadership during a challenging time. It's about transformation. Gerstner touches on the importance of speed and a clearly communicated set of principles—especially across a company as large as IBM was at the time. Gerstner also talks about the issues big companies run into with mid-level talent: "People do what you inspect, not what you expect."
Best quote: "I came to see, in my time at IBM, that culture isn't just one aspect of the game, it is the game. In the end, an organization is nothing more than the collective capacity of its people to create value."
Key points: This is by far the easiest read of the three in this post, but it's also the most effective at providing prescriptive and actionable leadership advice. Rossman, a former Amazon executive, decodes a lot of the behind the scenes at Amazon and points to what is most important at a company that complex: decision making and ownership. The owner of a project or product doesn't have to be the most senior person at the organization. In fact, it can be a very junior person. But this person is the sole person responsible for the project's outcome.
Best quote: "Amazon.com employees quickly learn that the phrase 'That's not my job' is an express ticket to an exit interview."
