TPS House
The foundation of the TPS house is the most overlooked component of TPS / Lean Management. Just like a real house the foundation needs to be large enough to support the walls and roof. The invested efforts on the foundation will assist in the sustainability of your system. We have made the foundation much thicker than the original to capture the implied understandings. The foundation consists of: 1. Customer First – A company exists because somebody is willing to pay for a service or product. Only the customer can determine the value of the product or service. 2. Respect for Humanity – Creating work environments that are safe and promote job enrichment. Utilizing the full talents of all Associates. 3. Genba - Actual worksite or workplace where the value is created. 4. Genchi Genbutsu – Actual place, actual thing also translated as “go and see.” Spend time observing the process versus hearing about it. 5. Stability - Refers to reliable machines, workforce and material. Kaizen is not a substitution for maintenance.
