Second there should the expectation when any task is started is that there will be transitions in any effort regardless of the time frame for completion. Transitions will occur as life situations among organizational participates change. Change is inevitable and should be expected. Having said that, how you share project information and with whom is something that should become the norm. The leader or team participant that doesn’t share program information is setting the organization up for transitional difficulties.
My final thought is that like athletic ability, you are either born with vision or not. It can be taught to a certain measure but most of it tends to be inborn. Embrace the person in your organization that “thinks outside the box.” They might be the best person to groom as a successor.
Still don't know if we are experiencing climate change? With the description of this weekend's Hurricane Irene being described as a "hundred year storm" haven't we been hearing weather events the past few years described as a hundred year event. Maybe with our changing climate we should no longer think these are hundred year events. Maybe we should say they are just this year's major weather event. A new normal.
