"In good organizations, people can focus on their work and have confidence that if they get their work done, good things will happen for both the company and them personally... In a poor organization, people spend much of their time fighting organizational boundaries, infighting and broken processes. They are not even clear on what their jobs are, so there is no way to know if they are getting the job done or not."

Telling the team "what" to do isn't enough—CEO authority alone won't get managers to comply. You have to explain "why," because managers can't get to everything and will silently reprioritize based on their own judgment of what matters.

When things go well, careers, resumes, money, and status all keep employees at a company. When things go wrong, the only thing left holding them is that they like their job. Being a good company is insurance against the inevitable downturn.

In technology companies, decline is a spiral: the company loses value, the best employees leave, the company loses more value, more employees leave. Spirals are extremely difficult to reverse—which is why culture matters before you need it.

Bill Campbell ran GO Corporation, which raised more money than almost any VC-backed startup in history and sold to AT&T for nearly nothing. Yet every GO employee Ben ever met called it the best work experience of their lives. That's what made Bill an amazingly effective CEO.

Ben's escalation to Steve: "You and Tim are preventing me from achieving my one and only goal. You have become a barrier blocking me from achieving my most important goal. As a result, if Tim doesn't meet with each one of his employees in the next 24 hours, I will have no choice but to fire him and to fire you." Sometimes protecting the culture requires making the stakes literal.

The Tommy Heinsohn cautionary tale: the Celtics coach won championships by yelling at his team, then had the worst record in the league because players stopped responding to his temper tantrums. Leadership tools wear out; leading by example and by example alone isn't enough either—your good habits don't get copied as reliably as your bad ones.
