In this conversation, we discuss their experiences and lessons on building cultures of continuous improvement that are rooted in respect, caring, and psychological safety.

Caroline brings rich experience as a Lean and continuous improvement coach, having partnered with organizations across different sectors to develop people and improve performance. Her background spans leadership development, organizational behavior, and a Master's degree in human resources management.

Chris is an award-winning author, international speaker, and a certified Shingo Institute Master-level facilitator and faculty fellow. He has more than 20 years of experience coaching executive teams and helping organizations embed sustainable improvement practices, always with a deep respect for people at the center.

In this episode, we explore topics such as:

• Practical approaches for leaders who want to build sustainable continuous improvement cultures.
• The origin story of Why Care and its message for leaders.
• Why caring cultures matter for both performance and people.
• Lessons from their Shingo Publication Award recognition.
• How psychological safety and respect for people underpin true Lean leadership.

• "Lean isn't just about tools or methods -- it's about people. If we don't care, we can't expect continuous improvement to last."
• "Respect for people means creating an environment where they feel safe, supported, and able to contribute. That's when real improvement happens."

• "Sustainable improvement starts with caring -- for people, for culture, and for the impact of our actions. Without that, Lean can't take root."
• "Psychological safety isn't soft; it's essential. It's what allows people to speak up, share problems, and drive meaningful change."

We may feature your question (and name) in a future episode — and yes, we’re doing a few Lean Coffee Talk mug giveaways for contributors ☕

• Building psychological safety while still holding people accountable

• Making Leader Standard Work more about behavior than calendar

In Episode 536 of the Lean Blog Interviews Podcast, Mark Graban talks with Carlos Scholz, the new CEO of Episode page with video, transcript, and more

In this episode, Carlos shares lessons from his Lean journey—starting with one-piece flow in apparel manufacturing and continuing through large-scale healthcare transformations. He explains why lasting improvement requires leaders to move beyond tools and rapid improvement events to embrace behaviors, principles, and a true Lean management system.

We also explore themes from his recent article, Leading Through Disruption: How Healthcare Leaders Can Respond. Carlos discusses the critical role of humility, vulnerability, and psychological safety in today’s leadership, and why leaders must sometimes “unlearn” old command-and-control habits to unlock engagement and creativity across their organizations.

Listeners will hear practical insights and real-world examples from Catalysis partners—including UMass Memorial, Ohio Health, and Zuckerberg San Francisco General—that demonstrate what’s possible when leaders fully commit to continuous improvement.
