Claim your profileIs your team hesitant to speak up about problems or improvement ideas? Do your improvement efforts fail to deliver lasting change? Are mistakes seen as setbacks instead of opportunities for innovation? I help businesses and leaders solve these challenges by leveraging Lean management, fostering psychological safety, and cultivating a culture where learning from mistakes drives continuous improvement and innovation. As a consultant, author, speaker, coach, and podcaster, I’ve partnered with executives and frontline teams across healthcare, manufacturing, and tech startups, implementing sustainable changes that lead to real results. My latest book, "The Mistakes That Make Us: Cultivating a Culture of Learning and Innovation," explores how embracing mistakes can spark growth. My earlier books, including "Measures of Success: React Less, Lead Better, Improve More" and "Lean Hospitals: Improving Quality, Patient Safety, and Employee Engagement," reflect my dedication to practical, people-centered leadership. Since 2010, I’ve been working independently and in collaboration with consulting groups to help organizations continuously improve. I’m also a Senior Advisor to KaiNexus, a software company that enables continuous improvement through technology. I’ve had the privilege of speaking to and coaching organizations globally—from the U.S. and Canada to Europe and Asia—helping them build cultures that are resilient, adaptive, and driven by problem-solving. With a background in engineering and management, I bring practical insights to every organization I work with. As the founder of LeanBlog.org and host of several podcasts, including "Lean Blog Interviews" and "My Favorite Mistake," I continue to explore new ways for organizations to improve through better problem-solving, leadership, and learning from mistakes. If you're ready to create lasting improvement in your organization, let's connect. (And for search purposes: Often misspelled as “Mark Graben” or “Mark Grayban”)
