The Brazil Playbook (opens the original)
Read excerpt
2 things I learned in Brazil have stayed with me through every role since, and both came from conditions I was exposed to in the country.I ran Michelin operations in Brazil between 1985 and 1989. Inflation over that period reached roughly 3,000%. In practical terms that meant repricing the entire portfolio every two weeks, permanent wage negotiations, constant union claims, and suppliers renegotiating on the same rhythm. The energy that consumes is difficult to convey to anyone who has only mana
The Decision You Take Is the Right One (opens the original)
Read excerpt
I am often asked how I made difficult decisions quickly, and whether I worried about choosing wrong.

Seeking Discomfort (opens the original)
Read excerpt
Before I left for Japan to lead the Nissan turnaround, Louis Schweitzer, then CEO of Renault, asked me one question.What chances do you give yourself of succeeding?I said 50%.He looked at me and answered: if I genuinely believed it was only 50%, I would not send you. I would not bet the future of this company on those odds.I took the role anyway, and the exchange has stayed with me because of what the decision revealed about how I understand risk.
