[Taiichi Ohno] thought [‘best practice’] a dangerous and misleading idea. ‘Best’ implies static, something ‘good’ that should be copied. He said that whenever you hear the word ‘best’, think ‘better’, because anything can be improved. Second, everything you need to know in order to make improvements will be found in your own system. If you go looking elsewhere, you will be looking in the wrong place."
