我們不需要完美的改善方案

One of the keys to process improvement is to realize that imperfect improvement is better than no improvement. Six months of imperfect improvements in a row leads to some pretty awesome results.

Root-Cause Analysis

I like these concepts:

• If something can go wrong, it will. (Murphy's Law)
• People are, well, people. Everybody makes mistakes.
• Everybody is doing the best job they can given their abilities and knowledge.
• When mistakes occur, blame your process, not people.

and the approach:

• Ask "why" five times

Manager

自為則不能任賢，不能任賢則群賢皆散
只做自己該做的事，不做部屬該做的事
