Anne's background in finance and healthcare administration provided her with a unique entry point into Lean -- first supporting improvement efforts through data, and then stepping fully into the role of change agent. She shares the story of how a persistent mentor who always asked "why" helped her shift from just reporting metrics to developing problem-solving thinking and leading transformation efforts herself.

In this conversation, Anne and I explore how Lean principles, such as respect for people, effective idea systems, and a problem-solving culture, manifest in real-world settings. She explains why she prioritizes coaching people to become relentless problem solvers and how systems like visual management and simple idea boards, when supported with good questions, can lead to safer, more efficient work. We also discuss how Lean applies differently (but effectively) across industries, the balance between improvement and documentation, and how to avoid siloed thinking when solving cross-functional challenges--especially in healthcare.

"A strong idea system is the first real show of respect for people--it tells the frontline we value their insight and want them to own the solution."

Anne also shares her perspective on Lean, Six Sigma, and Lean Six Sigma, offering a practical framework for how these approaches can coexist while serving different purposes. Throughout the episode, we reflect on systems thinking, psychological safety, and the importance of learning through experimentation. Whether you're in healthcare, manufacturing, or any people-centric industry, Anne's passion for leadership development and continuous improvement offers valuable insights.

• How did you first get exposed to Lean, and why did it resonate with you?
• Looking back, did your mentor's persistent "why" questions help develop your thinking more than if he had been directive?
