Jumia Books Trillion $ Coach By Bill Campbell, Blue In Color, Business

There is another, equally critical, factor for success in companies: teams that act as communities, integrating interest and putting aside differences to be individually and collectively obsessed with what's good for the company. Research shows that when people feel like they are part of a supportive community at work, they are more engaged with their jobs and more productive. Conversely, a lack of community is a leading factor in job burnout.

But to be most effective – and this was Bill's model – the coach works with the entire team. At Google, Bill didn't just meet with Eric. He worked with Jonathan and several other people, and he attended Eric's staff meetings on a regular basis. This can be a hard thing for an executive to accept – having a "coach" getting involved in staff meetings and other things can seem like a sign of lack of confidence.
