Key Quotes

Caroline Greenlee

• "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."

Chris Butterworth

• "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."
