In a turnaround, a leader's most critical first step is restructuring their direct reports. McLaren's CEO replaced every key leader—CFO, HR, commercial, etc.—to create a unified group that could then drive cultural change down through their own departments.

When diagnosing a failing department, stop looking for tactical issues. The problem is always the leader, full stop. A great leader can turn a mediocre team into a great one, but a mediocre leader will inevitably turn a great team mediocre. Don't waste time; solve the leadership problem first.

During a major crisis, a leader cannot rely on team consensus because everyone is still aligned with the old, now-invalid strategy. The CEO must dictate the new direction and be willing to be inconsistent to reset the organization quickly.

To combat complacency, Supercell's CEO opened an all-hands meeting by showing an animated slide of their declining global ranking year-by-year. This act of transparent and painful self-critique from the top created the psychological safety and urgency needed to rally the team around a new strategy.

Focusing on "bad to great" is more effective than "good to great" when scaling. Bad behaviors and destructive norms are so corrosive that they make it impossible for excellence to take root. A leader's first job in a turnaround or scaling effort is to eliminate the bad—like dirty bathrooms or incompetent employees—before trying to implement the good.

When a critical process like cash collection fails, use a tactic from Intel's Andy Grove: a daily 8 a.m. meeting where the CEO directly asks, "Where's my money?" This intense, unscalable focus rapidly uncovers and resolves the small, systemic blockers that are derailing the entire process.

People have an extreme aversion to acute pain. They will accept any level of chronic pain—like a company slowly bleeding out over five years—to avoid the single, difficult conversation or dramatic change required to stop the losing. This explains the long, slow death of many companies.

When confronting a talented but abrasive CTO, don't just critique bad behavior. Frame the conversation around their effectiveness. Horowitz suggests saying, "You're a fantastic Director of Engineering, but not an effective CTO," because a true CTO must marshal resources across the entire company, not just manage their own team well.

To combat complacency, Dell manufactures a crisis. He instructs his company to imagine a new, faster, more efficient competitor will put them out of business in five years. Their only path to survival is to proactively become that company first.
