A man gets off a train in a small village. As he steps onto the platform he looks around, lost. The new arrival spots an ancient old man dressed as a porter and asks, “Old man, can you tell me the way to Harthpenny House?” The old man looks at him and replies, “Well sir, if I were you, I wouldn’t start from here.”
It has been suggested to me a few times that we can dispense with the current state map. That we could go much faster if we just did a future state map and implemented the plan to get there. So I always tell that old joke. If you want to go anywhere you always have to start from “here”. You have no option. But in many organisations they don’t know where “here” is. So you have to find out. Otherwise you will take with you all the sources of variation and error on your travels.
