Toyota’s renowned production system (TPS) has long demonstrated the competitive advantage of continuous process improvement.
And companies in a wide range of industries—aerospace, metals processing, consumer products—have tried to imitate
TPS. Yet most fail.
Why? Managers adopt TPS’s obvious practices, without applying the four unwritten rules that make TPS successful. Like strands of DNA, these rules govern how people carry out their jobs, how they interact with each other, how products and services flow, and how people identify and address process problems. The rules rigidly specify how every activity— from the shop floor to the executive suite, from installing seat bolts to reconfiguring a manufacturing plant—should be performed.
Deviations from the specifications become instantly visible, prompting people to respond immediately with real-time experiments to eradicate problems in their own work. Result? A disciplined yet flexible and creative community of scientists who continually push Toyota closer to its zero-defects, just-in-time, no-waste ideal.
