BLUF: How do you stop the one person with "But, what if......" That slows, stalls and mainly disrupts management change.
You know the classic good idea or change effort that there is always a person who says "That's great but what if this happens like it did 10 years ago!"
Does the community have a answer to come back? Currently I say Ok, but we are looking for a 90% solution here. And seem to get another round of what if's.
