There is a long list of techniques that characterise the flow, pull and perfection parts of the Lean idea .
Notice how must time is always given to ‘Quick Changeover’; this is important since whilst things are stopped, the value stream is not flowing
Notice also that there isn’t any “Do this!”, rather what we learn are techniques to improve the flow of value streams .
If you can’t flow then pull is the next step .
And you can not do it all at once, so every improvement is a step on the way to perfection, but you never get there .
