Sometimes it takes the whole team.
Sometimes it takes a strategic part of the team.
Sometimes it even takes part of the team and some people from outside of the team to solve a problem.
And, sometimes the complete answer is with the leader. It doesn't have to be a paradox. What it does take is the honesty to gather feedback, look at the information available, talk to people on your team, and be willing to see the truth when it bubbles to the top. Can you do that?
Strong leaders know that sometimes they are not the answer to the problem. And sometimes they are.
