I've learned a lot over the years about building an effective team.
Start with a set of core values, and you have a built-in compass guiding each and every decision. Put together a set of clear processes, and you have an operating model that can stand up to any kind of change. Take an honest look at your people's strengths, and an organizational structure naturally takes shape around your processes. Instill a culture of continual improvement, and every team member will find a sense of purpose in their work.
Welcome all ideas. Communicate openly. Treat mistakes as learning opportunities.
Only then are you in the best position as a leader to set high expectations. Only then will your team want to exceed them.
