About Us
From the Toyota / Kuozui system to every shop floor in Taiwan — bringing an authentic TPS improvement culture with us.
It started at Kuozui Motors, inside the Toyota system
Mr. Lee Chao-Sen, who leads JINGJIN, is a former President of Kuozui Motors and a former independent director of Hotai Motor — an executive who grew up alongside Taiwan’s industry. We bring the lean management practice of the authentic Japanese Toyota Production System onto Taiwanese shop floors, so that the improvement capability forged inside a major manufacturer is available to every company that wants to keep getting better.
What Taiwanese companies are up against
How does a Taiwanese company survive and grow in the narrow space left by international competition? Many are now handing the business to a second generation — how do you make that transition work without costly detours? And as the AI wave arrives, how do you adapt quickly and put new technology to real use? These are the questions we work through alongside our clients.
Why JINGJIN exists
To bring the improvement capability of a major manufacturing system to Taiwan’s small and medium manufacturers.
A culture of lean improvement
Lean management (TPS) is our core. We strip it back until anyone can understand it and do it, so that improvement becomes part of daily work rather than a project — and eventually part of the company’s culture. We start with a single improvement theme, and we leave the method behind with your team.
Why we pair lean with AI and systems
Most of our IT team came from the information systems department of Kuozui Motors. They have run projects on live production floors and they were trained in the TPS way of thinking. We use systems integration, IoT, AI visual inspection, RPA and AI implementation planning to turn the results of lean improvement into data you can see and keep — first use TPS to clarify the process, then use systems to lock the improvement in.
Helping others succeed, building prosperity together
Expert guidance that breaks bottlenecks and drives growth
We are not just consultants — we are partners in your growth.
Through an experienced management team, we help companies manage better, compete harder and build businesses that last.
What sets us apart
An experienced management team: our lean practice comes from the Toyota system. Every consultant brings twenty to thirty years of experience across shop-floor manufacturing, production control, equipment, quality, HR and finance. We pass on the willingness to challenge the status quo, and we develop your own people into improvement leaders.
Systems integration that makes it stick: we integrate information systems, IoT and AI alongside lean improvement, so that new ways of working take root instead of fading out.
Finding your strengths, creating value together: we connect industry resources so that each party plays to its strengths and everyone gains.

A Message from Our Chairman
Looking back over my career, I spent it in Taiwan's automotive industry — as President of Kuozui Motors and as an independent director of Hotai Motor. Today I lead the team at JINGJIN TPS.
Those years inside a large corporation showed me how differently the pressure lands at each stage of a company's life, and they left me thinking about how to help more companies grow on steadier ground.
Lately I keep returning to the same questions. How does a Taiwanese company find room to survive and grow between the larger competitors? So many firms are handing over to a second generation — how do you make that succession work without losing years to avoidable mistakes? And as the wave of AI arrives, how does a company respond quickly enough to take hold of it? These are the real challenges of the current industrial environment, and they are what keeps many owners awake at night.
I see a great many capable business owners working hard to answer them. As someone who grew up alongside this industry, I wanted to do what I could to walk through these difficulties with them. So I brought together a group of specialists from different fields to form this advisory team, so that our combined experience could turn into help that companies can actually use.
Our team comes from different backgrounds — strategy, organisational management, information technology. We believe that combining several kinds of expertise gives a company both a fuller view and concrete ways to improve. Through systems integration and institutional discipline, we help companies build sound management systems, turning what used to depend on one person's experience into processes that outlast them, so that operations hold steady and decision-makers can face what comes next with more confidence.
We are also good at finding what each company is already strong at, and helping it push that strength further. And we value mutual benefit across the industry: by sharing experience and connecting resources, we help companies work together and grow together, building a healthier industrial ecosystem. For me, forming this team is not just a new milestone in a career — it is a responsibility and a commitment.
We will keep a humble, practical attitude, work from professional foundations, and walk honestly alongside every client. I hope we can contribute something to the lasting development of Taiwanese business, and that together we can move forward steadily through a time of change, and build a better future.

Where your data lives
Most of the companies we work with supply the electronics industry, and their own customers require absolute confidentiality. So we take a position on this before anyone asks: for project work, on-premises is the default. Building systems that run inside the plant is what this company does — the server and the database sit on your site, designed and built for each engagement.
To be clear about the standard product: PlainReport is currently offered as a cloud version and is listed in the MOEA Industrial Competitiveness Advisory Corps AI Tool Library. A fully offline, on-premises edition is still under development. If your data cannot leave the plant at all, the project route is the one to take today.
We take only the fields that are needed, sensitive values are replaced with codes whose mapping stays on your side, and when the work is done the source code, documentation and SBOM are handed over in full — so you can maintain it without us.
We do not hold ISO 27001 certification, and we say so early rather than let an audit find it. If you already have a supplier security questionnaire, send it over — we will fill it in and send it back, free of charge.
