The Toyota 4 Rules In Use
In their paper Decoding the DNA of the Toyota Production System, Harvard Business Review, 1999, S. Spear and H.K. Brown boiled down the essence of the Toyota method to these Lean 4 Rules In Use:
Rule 1) Clearly specify all Activities
- Content (what is being done?)
- Sequence (in what order?)
- Timing (how long should it take?)
- Outcome (what clearly defined measurable results are expected?)
Rule 2) Clearly define all Connections to every customer and supplier
- Direct (no intermediary between)
- Yes or No answers (no maybe)
Rule 3) Clearly define all Pathways
- Simple (with as few steps and people as possible)
- Direct steps to deliver the requested product or service
Rule 4) Continuously Improve
- Direct response to any problem that arises
- By those doing the work - as close to the problem as possible
- Whenever possible, start as an experiment
- Supported by a coach
