Four Rules of Problem Solving at Toyota
Harvard professors Steven Spear and Kent Bowen
followed some Toyota managers around to see what made the
Toyota Production System tick. After
studying what was happening on the floor, they coined the term "Community of

scientific method serves as one of the four rules that underlie

Rule 1. All work must be highly
Rule 2. Each customer-supplier
relationship is direct. This applies to both internal and external
customers and suppliers.
Rule 3. The pathway for each product and
service should be

Rule 4. Every employee uses what the
company calls the "pragmatic" scientific method to solve problems. The
method entails defining specifications, establishing hypotheses, continually
testing them and measuring the outcomes.
