Equipped with an engineering background from Chulalongkorn, Mie (Japan), and Mahidol University, Somchai “Mink” Boonphoapichart began his career at DENSO as a Process Engineer. With over 20 years on the shop floor, he steadily advanced to General Manager of Lean Automation.
This extensive hands-on experience forged a profound understanding of both production complexities and the human element. For him, understanding the “heart of the workforce” is the true catalyst for revolutionizing a modern Smart Factory.
How DENSO Drives a Resilient Smart Factory
When asked about the key success factors in preparing people and the organization for the Smart Factory transition, the insight from K. Mink (P’Mink) did not begin with machinery or AI. Instead, it focused on two fundamental Core Philosophies
1. DENSO Kaizen
When asked about DENSO‘s success in preparing its workforce and operations for the Smart Factory, Somchai emphasizes that the transformation doesn’t start with advanced machinery or AI. Instead, it is anchored in two core principles.
2. DENSO HRD
At DENSO, people development is the core pillar. Human potential is recognized as the organization’s greatest asset. No matter how advanced the technology becomes, sustainable growth is impossible without a prepared and empowered workforce.
Lean Automation Must Always Be Human-Centric
Mink’s core philosophy is clear: Lean Automation begins with people, not machines.
Integrating technology into the shop floor isn’t about replacing the workforce. Its true purpose is to empower employees to work smarter, safer, and with greater efficiency. Prioritizing technology over the human element inevitably leads to unsustainable results, operational resistance, and ultimately, a failed transformation.
Technology is Never the Ultimate Answer Without a Lean
Integrating digital systems, Automation, or AI into processes riddled with Waste doesn’t solve problems—it simply accelerates them.
Mink emphasizes that if the shop floor is still plagued by redundancies, waiting times, rework, and miscommunication, even the most expensive technological investments will fail to unlock their true value. This is the decisive reason why Lean must always precede Digitalization.
The Modern Factory Must Remain Human-Centric
Moving away from high-pressure, output-obsessed environments, the true vision of Lean Automation transforms the shop floor into a space where:
- People operate with absolute confidence.
- Systems actively reduce operational burdens.
- Technology serves as an enabler, not a dictator.
When employees feel valued, safe, and empowered to grow, sustainable operational excellence is finally unlocked.
From the Shop Floor to the Digital Business Landscape
The Inside the Factory Series highlights a crucial reality: Lean is no longer confined to the manufacturing line. It has evolved into the universal language for every organization in the digital era. Whether a tech startup racing against time and capital, an e-commerce platform managing volatile demand, or a complex large-scale enterprise, all face the same operational bottlenecks. Every organization struggles with redundant tasks that drain human potential, process delays that erode business opportunities, and fragmented data that clouds decision-making. This is where Lean principles provide a decisive edge, unlocking unparalleled agility and empowering organizations to adapt swiftly, make razor-sharp decisions, and master continuous change.
Having explored the macro view of Lean Automation and the modern Smart Factory, we dive deeper with Mink. The following Q&A uncovers practical strategies, actionable insights, and hard-earned shop floor lessons ready to revolutionize your operations
