In this episode of People Solve Problems, host Jamie Flinchbaugh welcomes Dr. Greg Jacobson, CEO and Co-founder of KaiNexus, for an insightful conversation about the intersection of medical training, psychological safety, and continuous improvement culture.
Greg’s journey into the world of Lean and Kaizen began in 2004 when his department chairman handed him Masaaki Imai’s book “Kaizen” and said, “You think like this.” As an emergency medicine doctor, Greg was immediately struck by the realization that there was an entire discipline focused on improving systems. He recognized that healthcare had so many operational inefficiencies that applying these principles in the emergency department could yield tremendous results through solving basic problems and capturing low-hanging fruit.
The conversation explores how Greg’s medical background both helps and hinders systematic thinking about business problems. He explains that physicians are trained with a scientific mindset where every patient encounter resembles an experiment – gathering evidence, forming hypotheses, running tests, and evaluating outcomes. This mirrors the problem-solving methodology used in Lean thinking, making the transition natural for some medical professionals. However, the competitive nature required to succeed in medical school and residency can create fixed mindsets and reduce curiosity, as many doctors become accustomed to being the “alpha dog” who always has the right answers.
A significant portion of the discussion focuses on psychological safety and its critical role in enabling improvement. Greg defines psychological safety as “being rewarded for being vulnerable” – whether that’s admitting you don’t know something, raising concerns about broken processes, or challenging existing systems. Through his experience working in emergency departments across the United States and even New Zealand, he observed that departments where people felt safe to speak up consistently had better outcomes than those where the culture encouraged keeping quiet and just getting the job done.
Jamie and Greg explore how technology systems can actually enhance psychological safety by creating a buffer between individuals and problems. When issues are logged in a system rather than raised face-to-face, it shifts the dynamic from personal confrontation to collaborative problem-solving. The issue becomes the common enemy that everyone works together to address, rather than a source of interpersonal tension. Greg notes that rather than reducing human interaction, electronic systems actually increase communication by creating visibility and fostering engagement around improvement opportunities.
The conversation turns to habit science and its application to continuous improvement culture. Greg credits reading “The Power of Habit” by Charles Duhigg, “Atomic Habits” by James Clear, and “Tiny Habits” by BJ Fogg with transforming both his personal life and his understanding of organizational change. He explains how KaiNexus applies the habit loop concept – cue, routine, reward – to create interconnected behaviors across different organizational levels. The routine of one person becomes the trigger for another person’s habit, creating a web of positive behaviors that sustain improvement culture.
When asked about his personal habit transformation, Greg shares how he moved from being an inconsistent squash player who would “demolish his body” once or twice a week to someone who exercises daily. After tearing his ACL in his forties, he used habit science principles to change his identity and create sustainable physical activity routines.
Throughout the discussion, Greg emphasizes that KaiNexus is fundamentally about the human transformation that technology enables, not the technology itself. The platform’s value comes from people interacting with it in specific ways that foster continuous improvement behaviors across the organization.
