The idea is that leaders need to be scouting ahead for the resources and direction needed for success. For example, managers need to be focused on the next couple of quarters while people working in a function work toward a successful couple of months. The next level leader should be focused on a successful couple of years, and so on.
This idea completely meshes with a section from my upcoming book The Ripple Effect, where I talk about leaders needing to be just a half-step ahead of their teams. Too far ahead and the leader can't benefit from what the team sees, not to mention that the team will feel disconnected from the leader. Not far ahead enough and the team will be hesitant to take risks.
The balance is for the leader looking and being far enough ahead, yet staying connected to the team and the reality team members are dealing with.
So - how far ahead are you ahead of your team? Or better yet - how's your team doing with where you are?
