- Lucas: In the early 1950s, Toyota was on the brink of bankruptcy. The company was producing fewer than 40,000 vehicles a year — Ford was making over 1.5 million. And yet, within two decades, Toyota would overtake its American rivals and become the world's largest automaker. Luna: That's an insane turnaround. What changed? Lucas: What changed was a production philosophy so radical it's still studied in business schools today: the Toyota Production System. It's not just about cars — it's about how you organize work itself. Luna: And it's famously credited to one man, right? Taiichi Ohno. Lucas: Yes. Ohno was an industrial engineer at Toyota, and he looked at American mass production — think Henry Ford's assembly line — and saw massive waste. Huge inventories, machines sitting idle, workers doing repetitive tasks with no input. He wanted to build a system that was leaner and more flexible. Luna: So what was his big insight? Lucas: He had two core ideas. The first is just-in-time production: make only what you need, when you need it, in the quantity you need. No huge stockpiles of parts. And the second is jidoka — which translates roughly to 'automation with a human touch.' It means if a problem occurs, the machine stops automatically, and workers are empowered to fix it on the spot. Luna: That second one seems almost counterintuitive. Stopping the line sounds like the opposite of efficiency. Lucas: Right, and that's the genius. At most factories, stopping the line is a catastrophe. But at Toyota, any worker can pull the andon cord — a literal cord that runs along the assembly line — to stop production if they spot a defect. The idea is that you fix the problem immediately, rather than letting it accumulate and cause bigger issues downstream. Luna: So it's about building quality into the process, not inspecting it in at the end. Lucas: Exactly. And this ties into another pillar of the system: kaizen, or continuous improvement. Every employee, from the assembly line to the executive suite, is expected to suggest small, incremental improvements. It's not about big breakthroughs — it's about hundreds of tiny tweaks that add up over time. Luna: I've heard that Toyota receives millions of improvement suggestions from employees every year. And a huge percentage are actually implemented. Lucas: That's right. In 2023, Toyota reported over 7 million improvement suggestions from its global workforce, with an implementation rate of around 90 percent. That's not a suggestion box — that's a culture. Luna: And it's not just manufacturing. Hospitals, software companies, even the military have adopted lean principles. But I wonder — does the Toyota Production System have any weaknesses? Lucas: It does. The system is incredibly efficient in a stable environment, but it's fragile. The whole just-in-time model relies on a perfectly synchronized supply chain. If one supplier has a disruption — say, an earthquake in Japan or a fire at a parts plant — the entire production line can grind to a halt. We saw that in 2011 after the Fukushima disaster, and again during the pandemic. Luna: So there's a tension between lean efficiency and resilience. Some companies have started holding buffer inventory as a hedge. Lucas: Exactly. Toyota itself has dialed back its just-in-time approach slightly. But the core principles — continuous improvement, respect for people, problem-solving at the source — those are as relevant as ever. And they've spread far beyond Toyota. Luna: You know, listening to this, I'm reminded how much these conversations have shaped my own thinking about work. And it makes me think — if you've gotten value from this show, there's a small way to keep it going. Lucas: Yeah, we keep the podcast ad-free and independent, and listener support is genuinely what makes that possible. A couple of dollars a month — you can think of it as buying us a coffee. The link is buy me a coffee dot com slash fexingo. Luna: It's a small gesture, but it adds up and lets us keep digging into stories like this one. Lucas: Absolutely. So back to Toyota — one of the most tangible examples of Ohno's system is something called single-minute exchange of die. That's the process of changing the heavy stamping dies that press car body panels. Luna: I've heard this story. In the 1950s, it took Toyota hours to change a die. Ford took a full day. Lucas: Right. Ohno studied the process and realized that most of the time was spent searching for tools, adjusting settings, and waiting. By standardizing the procedure, training workers, and using quick-release mechanisms, Toyota reduced die change time to under ten minutes — hence 'single-minute.' That meant they could run smaller batches, which reduced inventory and increased flexibility. Luna: And that flexibility allowed Toyota to respond faster to customer demand. They could produce a mix of models on the same assembly line. Lucas: Precisely. By the 1970s, when oil shocks hit and demand shifted from gas-guzzlers to smaller cars, Toyota could adapt almost overnight. Detroit was stuck with huge inventories of big cars they couldn't sell. That wasn't luck — it was the system. Luna: It's a powerful lesson. The system itself was the competitive advantage, not just the product. Lucas: And that's the takeaway for any leader. Your processes — how you make decisions, how you handle problems, how you treat your people — those are harder to copy than a product. Toyota's factories have been studied for decades, but no one has fully replicated their culture. Because culture isn't a checklist — it's built over years of daily practice. Luna: So the real question is: are you building a system that improves itself, or one that just runs? Lucas: That's the question every CEO should ask.
