Impossible

“Impossible Is Not a Fact. It’s an Opinion.”

"Impossible is just a big word thrown around by small men who find it easier to live in the world they've been given than to explore the power they have to change it. Impossible is not a fact. It's an opinion. Impossible is not a declaration. It's a dare. Impossible is potential. Impossible is temporary. Impossible is nothing." ~ Muhammad Ali

In Lean we have to do the impossible.  Shortening lead times, increasing productivity and improving quality are the easy parts.  The part that can fill me with trepidation, because I can never know if I can do it is to take the people with me on the journey.   What part of Lean is the 'impossible' part for you?

For an alternative view on impossible:
"The impossible often has a kind of integrity the merely improbable lacks." ~Douglas Adams
