Let’s discuss your audience and goals. Speaking topics: https://www.markgraban.com/speaking/topics/ Booking inquiries: https://www.markgraban.com/speaking/book-mark/
Mark Graban Speaker Reel | Psychological Safety & Leadership
A patient was supposed to undergo surgery for a right-sided inguinal hernia. But the incision was made on the left side. Dr. David Mayer, then a senior anesthesia resident, recalls how the operating room team moved quickly into the procedure while everyone focused on their own responsibilities. About two minutes after the incision, the attending surgeon entered the room, looked at the patient, and asked: “I thought this was a right-sided inguinal hernia?” That was the moment the team realized what had happened. In this clip from *My Favorite Mistake*, Dr. Mayer describes the wrong-site surgery that became a defining experience in his career—and helped shape his commitment to patient safety, transparency, and learning from medical errors. The larger lesson isn’t simply “be more careful.” It’s to understand how systems, communication, time pressure, teamwork, and culture can allow an error to reach a patient.

Wrong-Site Surgery: The Mistake Discovered Mid-Procedure
How did Toyota’s Georgetown, Kentucky plant go from needing to build almost 90% of its capacity just to break even, to a much healthier 60%? Former Toyota team member Darril Wilburn, co-author with Hiro Yoshiki of Courage, Humility, Kaizen: The Three Disciplines of Toyota Leadership, tells the inside story. We talk about the andon cord myth, “healthy paranoia,” why Toyota never talked about being number one, sending managers back through jishuken, why every VP’s first A3 was sent back by design, and why doing TPS was never the point. Full episode page, links, show notes, and transcript: https://leanblog.org/551 What you’ll learn: 🔵 What really happens when someone pulls the andon cord 🔵 Why psychological safety at Toyota includes being challenged 🔵 How “healthy paranoia” keeps an organization from getting complacent 🔵 How TMMK cut its break-even point from nearly 90% to 60% 🔵 Why Hiro Yoshiki rejected blame and focused on equipping people to succeed 🔵 How Toyota turned its masters’ know-how into teachable curriculum 🔵 Why humility had to be built into how executives were developed Chapters: 00:00 Introducing Darril Wilburn and Courage, Humility, Kaizen 01:47 How Darril met Hiro Yoshiki 05:52 The andon cord myth 07:59 How andon escalation actually works 11:35 Building psychological safety before line-off 13:23 Respect for humanity includes challenge 15:56 Healthy paranoia 18:36 Why Toyota didn’t talk about being number one 20:03 Toyota’s careful entry into the U.S. 22:36 Rapid expansion and a 90% break-even point 24:47 The turnaround: from 90% to 60% 25:39 No blame 27:00 Pulling wisdom out of the masters 30:36 Why expertise had to be dragged out 33:52 Breaking the cycle of rescue teams 35:11 Jishuken and the humility to relearn 37:04 Straight talk instead of spin 40:35 Hiro, not heroes 42:52 Formal and informal communication 46:08 Can you help someone become more humble? 47:42 Every VP sent back on the first A3 51:07 “Doing TPS was never the point” 52:32 Toyota is a business 53:48 Stop counting kaizens when you’re losing money 54:36 Closing Subscribe to Lean Blog Interviews for more conversations on Lean, leadership, continuous improvement, and psychological safety: http://leancast.org/ #Toyota #LeanManagement #ToyotaWay #Kaizen #Leadership #ContinuousImprovement #PsychologicalSafety
