“Change can only begin when you admit you don’t know everything.”
Behind each change is an admission that there may be a better way of doing things. This admission has to happen at all levels. It must be accompanied with a willingness to explore new ways of working and doing things.
It’s fine to say “If it’s not broken don’t fix it” but just because it’s not broken doesn’t mean we should not try to improve it.
The power of change is quickly extinguished by all of us when we respond too quickly with “no, it’s not possible” or “we tried that already and it didn’t work”. Change needs momentum to start. Even if you tried it before, doing it again might deliver exactly the same outcome but the learning is big part of the Lean Principles.
So if you are a manager and leader, give your team bandwidth to explore their ideas and avoid shutting them down.
The team might just learn a valuable lesson and perhaps find another idea that no one has ever thought about.
