#1: Keeping TPS/Lean Human-Centric: Using Digital Tools to Empower, Not Replace
Kicking off the Leveraging TPS/Lean for Transformation in the Digital Era blog series, we’ll explore how TPS/Lean can be enhanced with digital tools to drive meaningful transformation. I'll use the terms TPS and Lean interchangeably, focusing on their role in value creation, problem-solving, and continuous improvement in the digital age.
TPS/Lean tools offer a wealth of tools —but at their core, they are just that: tools.
The Toyota Production System (TPS) has thrived for over 80 years, not because of tools alone, but because it is built on these fundamental principles:
✅ Customer First
✅ Respect for People
✅ Continuous Improvement
✅ Shop Floor First, Go Look/Go See
With the rise of AI, automation, and digital tools, businesses who are implementing TPS/Lean must ask: Do these technologies align with the TPS principles, or are they just the latest trend?
TPS was designed to drive customer value, not just efficiency. AI and digital tools must serve the same purpose because, without alignment to value, they become costly distractions rather than game-changers.
Too often, companies adopt AI and digital tools without first defining the real problem. Is technology solving a business need—or is it just another Industry 4.0 buzzword in search of a problem?
The Risk of Tech-First Thinking
AI and digital tools are undoubtedly powerful, as they can analyze data, automate routine tasks, and even predict failures before they happen.
But let’s be clear: AI and digital tools should support people, not replace them.
The risk? Adopting digital tools without clearly defining the problem and integrating TPS principles can lead to the erosion of problem-solving skills, bloated systems, and added complexity.
Companies often fall into the trap of technology-first thinking, where digital initiatives become an IT project rather than a business improvement effort.
This happens when:
Technology drives decisions instead of business or operational needs.
Data replaces direct observation, removing real-world context.
Over-automation reduces ownership, making teams reactive instead of proactive.
Complexity increases, creating inefficiencies instead of eliminating them.
To truly harness the power of technology, it must be integrated thoughtfully, solving real problems in the most human-centric way, rather than simply adding complexity.
Trending Technologies as Game Changers
As businesses embrace the digital revolution, several technologies have gained attention for their potential to transform operations. While these tools can drive efficiency and provide deeper insights, they also come with challenges and limitations.
Here's a closer look at some of the most talked-about technologies:
Digital Twin Technology: By creating virtual replicas of physical systems, digital twins provide deep insights into operational processes, but too much complexity and data quality issues, can overshadow practical hands-on problem-solving.
IoT and Smart Sensors: Great for real-time data gathering but they shouldn’t replace direct observation. The human aspect is key to understanding real-world context (the meaning behind the data).
Robotic Process Automation (RPA): RPA promises to streamline repetitive tasks, freeing up valuable human resources for more value-added tasks. However, if you automate processes without eliminating the non-value-added work, you are just automating waste faster.
Blockchain for Supply Chain: Helps mitigate risks and enhances inventory management by increasing transparency, however, it can create challenges with its “Black box” nature.
Augmented Reality (AR) for Training: Provides immersive and interactive training experiences, but should complement, not replace, hands-on experience. Improving skills comes from practices in the field, not just simulations.
While these technologies hold great potential, they should always serve to enhance human decision-making and support TPS principles.
The Real Competitive Advantage
At Toyota, competitors are welcome to visit their plants, not because Toyota doesn’t value secrecy, but because they know the real secret: What competitors see, they cannot copy.
The real competitive edge isn’t the TPS tools—it’s the people and problem-solving mindset behind them.
TPS was built to create value for the customer and often fails because companies “mechanically” apply the tools without fostering a continuous improvement culture. Similarly, digital tools will fall short if companies chase technology without a clear focus on value creation, becoming another costly solution that adds unnecessary complexity.
