Philosophy, Process, People, and Problem Solving as the foundation of operational excellence

Improvement is eternal and infinite; build a system where every person, every day, surfaces problems and makes things a little better

Identify and ruthlessly eliminate the seven categories of waste that inflate costs without adding any value for the customer

Ask why five times to penetrate from symptoms to root causes, turning every problem into a permanent improvement

Use simple visual signals attached to goods to pull production through the system, making overproduction impossible and waste visible

Build quality into the process by giving machines and workers the authority to stop production the moment an abnormality occurs

Produce only what is needed, when it is needed, in the amount needed to eliminate waste and approach zero inventory
