Psychological Safety, Learning from Mistakes, and Continuous Improvement
from Lean Blog Audio: Practical Lean Thinking, Psychological Safety, and Continuous Improvement Hosted by Mark Graban
The blog post Many improvement efforts stall not because of poor strategy or missing Lean tools, but because people don’t feel safe speaking up. In this Lean Blog Audio episode, Mark Graban explains why psychological safety is a foundational requirement for continuous improvement. Drawing from his book The Mistakes That Make Us and decades of experience in healthcare, manufacturing, and other industries, Mark explores how fear, blame, and leader reactions silence learning — and how different leadership behaviors make improvement possible. The episode also previews themes from Mark’s upcoming workshop at Shingo Connect 2026, including what psychological safety is (and is not), how it supports accountability rather than lowering standards, and why learning from mistakes depends on creating environments where people can speak honestly without fear.
