The Blunder Belt Letters

By Dave Cortes

Where every improvement is a step toward a glorious failure.

Meet Mr. Blunder, a Lean Six Sigma Black Belt with a PhD in corporate chaos and a master's degree in making things worse. In The Blunder Belt Letters, he shares his catastrophically bad advice with a struggling pharmaceutical plant, guiding them through a series of process improvements so misguided, they should qualify as sabotage.

Through hilariously disastrous letters, watch as a once-functional factory transforms into a case study in inefficiency, thanks to rushed certifications, hidden Lean boards, half-baked automation, and leadership strategies straight from a Dilbert cartoon.

This book is a must-read for Lean Six Sigma professionals, corporate survivors, and anyone who has witnessed an "improvement" that made everything worse.

Because sometimes, the best way to understand success is to watch a master of failure at work.
