Pre-read 1: The Law of the Lid
Think of a container with a lid. Nothing inside can rise above the lid. Your leadership ability is that lid. Your team, your work, and your career cannot rise above it.
The standard first: Google Project Oxygen
In 2008, Google tried to prove that managers do not matter. Google was built by engineers. Most of them believed that great engineers plus freedom equals great results, and that managers only add cost. Project Oxygen was the data project meant to prove that.
It found the opposite. Manager quality can be measured, and it predicts team results, how long people stay, and how happy they are. Google turned the difference between its best and worst managers into a ranked list of behaviors (the Oxygen behaviors). The top of the list was not technical skill. It was coaching, giving people room to work, and caring about people. Technical skill was on the list, but near the bottom.
Other data agrees. Gallup studied many workplaces and found that about 70 percent of the difference in team engagement comes from one factor: the manager. The person who leads is the ceiling.
The second dataset: the Peter Principle, measured
The Peter Principle is an old joke with truth in it: companies promote people until they reach a job they are not good at. The best salesperson becomes a weak sales manager. In 2019, three researchers (Benson, Li, and Shue) tested this with real data from 214 companies and about 53,000 sales workers. The result: companies really do promote the best individual performers, and individual performance really does not predict who will be a good manager. The best predictor was different: a history of working well with others.
Engineering career ladders have the same trap. The strongest coder becomes the lead. The thing that made them strong (personal output) is exactly what they must now stop focusing on.
The law behind the standard
Maxwell's claim is direct: your impact is limited by your leadership ability, the way a container is limited by its lid. If your technical skill is a 9 out of 10, but your leadership is a 4, your real impact runs at the 4. Why? Because everything big needs other people, and moving other people is leadership.
Success without leadership only grows as far as one person's own hands.
On your track
- IC (Staff/Principal): your lid limits how far people adopt your designs, the same way it limits a team's output. A great design that nobody follows is a leadership problem, not a design problem. The Peter Principle study also explains why some Staff promotions get stuck: personal output stops being the signal.
- Lead/EM: Project Oxygen measured people in your role. Manager quality sets the ceiling for team performance, and that ceiling is yours to raise.
The story: Xerox PARC
Xerox PARC invented the graphical user interface, the mouse, ethernet, and laser printing. Almost none of the value went to Xerox. The technology was a 10. The leadership above it could not turn invention into direction, so Apple and other companies took the value. The best technical work in history, held down by a lid.
Before the session
Come to the session with one question this reading left you with. If you need a starting point, think about one of these:
- Where, in the last 3 months, did your technical skill and your leadership skill give clearly different results?
- The hard question we will spend session time on: what do you do about a lid you cannot see?
