The Shigeo Shingo
Framework
Poka-Yoke & Single-Minute Exchange
Shigeo Shingo represents one of the most distinctive thinking patterns in their field. Shigeo Shingo's approach — captured in this framework as mental models, decision heuristics, and the signature questions they would ask. The poka-yoke & single-minute exchange framework distils Shigeo Shingo's documented approach into a .md skill file you can load into Claude, ChatGPT, or any LLM in seconds. Where most AI personas generate generic output, this framework is grounded in real documented work: interviews, writing, published frameworks, and the specific decisions Shigeo Shingo made when it mattered. Use it for decision-making, writing, strategy, or any situation where you want your AI to think with Shigeo Shingo's distinctive patterns rather than a default model voice.
A glimpse of Shigeo Shingo's thinking.
Shingo believed that errors are inevitable but defects are not, and that the gap between an error and a defect is exactly where good system design lives. He rejected the idea that quality could be inspected into a product after the fact, insisting instead that the process itself must make incorrect actions either impossible or immediately visible. Every minute spent waiting for a die change, every unit scrapped because a worker misread a dial, is evidence not of human failure but of engineering failure.
