Admitting mistakes is the first step to learning, not just for you, but also for your team and company
Admitting you committed a mistake is a very important part of continuous improvement. The andon cord (a sort of error alarm) should be pulled as soon as an mistake/error/defect is created or found.
Finding mistakes is not a blame game in Lean thinking, it is a key part of finding ways to avoid mistakes altogether through poka-yoke or mistake proofing our work methods!
Behind this willingness to show and learn from mistakes we make are some concepts in the Toyota Product System (TPS):
- If the student has not learned the professor has not taught.
- Most mistakes are caused by the situation or the system and not by people's incompetence or willingness to do their best.
- Respect for people (one of the key pillars of the TPS)
