No fixing of blame. Perhaps we can learn from this brilliant locution. Create a company of learners with a formal debriefing policy. Without one, learning from mistakes is just one more accident. Debrief everything - good, bad or indifferent.

Forget about total quality and zero defects. You can't afford it, especially in this day and age.

Use the errors you generate as opportunities to improve your production process and practice great customer service. Remember, the hallmark of progress is making mistakes.
