Great vision precedes great achievement. Every team needs a compelling vision to give it direction. A team without vision is, at worst, purposeless. At best, it's subject to the personal, and sometimes selfish, agendas of various team members. As the agendas work against each other within your environment, the team's energy and drive drain away. On the other hand, a team that embraces vision becomes focused, energized, confident, intentful, and it knows where it's headed and why it's going there.
Remember, vision gives team members direction and confidence. What is your vision? What are you doing to build the confidence of your team?
