Episode blog post with video, transcript, and more My guest for Episode #535 of the Lean Blog Interviews Podcast is Gregg Stocker, a seasoned Lean practitioner, consultant, and author. Over the past 30+ years, Gregg has worked across industries, including oil and gas, energy services, manufacturing, and construction, guiding both independent operators and major corporations on their Lean journeys. He is the author of Profitable at Any Price: Lean Thinking for Safer, Cheaper, and More Responsible Oil and Gas Production and is revising his earlier book Avoiding the Corporate Death Spiral. In this conversation, Gregg shares his Lean origin story, which began with exposure to Dr. W. Edwards Deming's teachings in college and later expanded through hands-on work with Toyota. We discuss the importance of daily Kaizen, the influence of Deming's philosophy of profound knowledge, and why psychological safety and systems thinking are essential to effective Lean leadership. Gregg also reflects on his experiences helping organizations in high-risk industries such as oil and gas. He explains how Lean thinking can simultaneously drive improvements in safety, cost, and reliability -- showing that these are not trade-offs, but outcomes of a stronger system. Listeners will hear stories of transformation, lessons from Toyota, and practical insights on structured problem-solving, leadership behaviors, and building a culture where people feel safe speaking up. Whether you work in energy, healthcare, manufacturing, or any other sector, Gregg's insights are broadly applicable. This episode is a reminder that Lean isn't just about tools -- it's about leadership, systems thinking, and creating conditions for continuous improvement.
