Neat little article: The Atomic Rules of Kaizen.  From the article:

Systems that are internally consistent and externally pragmatic stem from just a few rules.  Systems with exceedingly many rules typically fail or will not endure….

In Kaizen, it is important to have fidelity to just a few atomic rules, from which a range of behavior will originate.  Below are the rules that I subscribe to:

1. Spend no Money
2. Add no People
3. Add no Space
4. Add no Steps (Touches)

I like the idea of having simple rules like this.  The short list is memorable.
