- Strive for continuous improvement. Things can always get better no matter how good or bad they may be now.
- Always questions tradition and, when necessary, discard the old to make way for the new.
- Acquire wisdom by consulting with many people rather than relying on one expert.
- Don’t waste time making excuses but focus on finding solutions.
- Make sure you base your decisions on facts rather than opinions.
- Get to the root cause of a situation or problem by asking “Why?” at least 5 times.
- Before spending money to fix a problem, look for simple and inexpensive solutions.
- Always question the status quo.
- Start making improvements right away, even if you don’t yet have all the answers.
- Make sure everyone is involved. Real change must include everyone who works on a project, not only those at the top. At Toyota, for example, any worker has the authority to stop production if he notices a problem.
