Toyota Production System

Taiichi Ohno created the Toyota Production System (TPS), the foundation of lean manufacturing and the intellectual ancestor of most modern flow-based thinking in software. His key innovations include kanban (visual signals for pull-based production), just-in-time manufacturing, and the practice of going to the gemba (the actual place where work happens) to observe reality firsthand rather than relying on reports.

Ohno’s influence runs through nearly everything in this vault related to flow, WIP limits, and continuous improvement. His insistence on direct observation over abstraction is the foundation of Gemba walks, and his pull-based thinking is the reason we treat WIP limits as non-negotiable.
