As a pioneer of adapting lean thinking to software engineering, I have dreamed for a long time of eradicating bugs and building right-first-time software. But the step from very good quality to 0 bugs, at scale, without just relying on stable experienced teams, seemed too hard.

Until I stumbled on a book: the Toyota way of Dantotsu Radical Quality Improvement. A step-by-step, no-bullshit, guide by Sadao Nomura who explains how he reduced defects in four factories already considered world-class in terms of quality… by another 90%!!

This is the story of how this book convinced us that going beyond good quality towards radical “dantotsu” quality is possible, and how we are adapting it at the moment to our software engineering settings with promising results.
