Fix the Factory, Not the Flowchart isn’t just another Lean book. It’s a battle cry.
For too long, we’ve mistaken tools for transformation—chasing certifications, dashboards, and playbooks while the real problems fester under fluorescent lights and forgotten people.
This book goes where most don’t: the floor, the hallway, the meeting room where hard truths live.
Through fierce stories, unfiltered insights, and rebel hacks, it exposes why most change fails—and how to lead with guts, not gimmicks.
If you’re done with surface-level Lean and ready to fix what really matters—this is your manifesto.
Because real Lean doesn’t live in templates.
It lives in people brave enough to change the system — not just survive it.
