One of the very first lessons we learn when we start down the road of our lean journey (highway to hell, the green mile, etc.) s that we need to go and see for ourselves. We need to see problems with our own eyes, Don't rely on lengthy reports, or make judgements about problems and definitely don't jump to solutions. We are taught early on that we need to "go to the Gemba".
A3 closings? Also best done at GEMBA, not ROOMBA. I know there are challenges (noise, etc.), but it is so easy for the beauty of the improvement and the thinking to shine through when people are actually looking at it.
Be that squeaky wheel that speaks up when you feel rigor mortis setting in at the ROOMBA....."hey, why don't we just go and see?"
