After a year or so doing every job in the bakery, you have credibility with the crew you’re leading because they all know you could do their job. You have a complete, holistic understanding of the bakery in a way that no individual does. You’ve had a chance to watch good managers and bad, you’ve experienced a lot of the things that can go wrong and seen how to fix them (and how not to fix them), and you can be trusted to drive a fifty million dollar factory that churns out hundreds of thousands of loaves every night.
