That’s exactly what longtime Toyota leader Isao Yoshino was tasked with during one of the most famous business transformations in history—NUMMI—Toyota’s joint venture with General Motors in the 1980s.

The challenge?

Take GM’s worst-performing plant—plagued by absenteeism, low morale, and poor quality—and turn it around.

Within just one year, with the same American workforce but under Toyota’s leadership, NUMMI became GM’s best-performing site.

Behind the scenes was Mr. Yoshino, leading the design and delivery of a three-week training program in Japan for hundreds of NUMMI’s frontline and middle managers.

In this episode, Mr. Yoshino shares the inside story of NUMMI’s transformation—how an experiment in a business turnaround became a “New Me” moment for its leaders—and the leadership lessons you can use to influence culture change without relying on authority.

If you’re a lean practitioner or change leader wondering how to truly “change a culture,” this is a rare chance to hear the story directly from the person who lived it.

You’ll Learn:

• Why you can’t force culture change—and what to do instead
• How Mr. Yoshino and his team created immersive learning experiences that shifted NUMMI leaders’ mindsets in just three weeks
• Why the “Check” step in PDCA is the secret to Toyota’s sustained success
• How the andon process reshaped leaders’ views on problems—and how a “no problem is a problem” and no-blame mindset fosters learning and continuous improvement
• Why NUMMI’s transformation was as much (or more) about people as it was about performance
