As a manager, be careful about focusing on your teams to the exclusion of the wider group. Even when you have been hired to fix a team, remember that the company has gotten this far because of some fundamental strengths. Before you try to change everything to fit your vision, take the time to understand the company’s strengths and culture, and think about how you’re going to create a team that works well with this culture, not against it. The trick is not to focus on what’s broken, but to identify existing strengths and cultivate them.
