When “Old Chen” Retires
“Old Chen is retiring next month.”
When that news spread across the workshop, the whole place fell silent.
Old Chen is the most experienced engineer in the factory.
He can tell—just by looking at a drawing—where the machining challenges are.
He knows every machine’s “temper,” which parts run best on which equipment, and how to plan the most efficient process without even checking the manual.
For years, his experience has been the invisible safety net of the production line.
But now, he’s about to retire… and the question hangs in the air:
Who will inherit all that invisible knowledge?
Many manufacturing companies face the same dilemma.
In most factories, process judgments during design depend entirely on a few senior engineers.
Quotations take days of manual analysis.
Work instructions pile up, incomplete and outdated.
And vital documents—drawings, PDFs, BOMs, SOPs—lie scattered across servers like forgotten treasures.
When those key people retire or leave, production suddenly stalls.
Process evaluations get delayed, quotation cycles stretch out, and all those years of expertise vanish into thin air.
The real loss: invisible knowledge
We can sum up this “invisible wealth” into three forms:
The experience locked inside engineers’ minds
The knowledge buried in dusty documents
The process know-how that’s impossible to standardize or retrieve
01
The Root Cause: Knowledge Has No “Digital Life”
Knowledge loss is far more severe than most factories realize—especially in custom and non-standard parts manufacturing.
Design reviews, DFM checks, and cost estimation often rely on intuition, not data.
That leads to three serious problems:
1. Efficiency drops.
Once the veterans leave, project evaluation slows, and response time increases drastically.
2. Quality becomes unstable.
New staff lack the “hidden standards” embedded in experience, leading to repeated mistakes and quality variation.
3. Innovation stagnates.
When knowledge stays in people’s heads instead of systems, it can’t be scaled, shared, or reused.
So what if your factory could have a “Digital Old Chen”?
Imagine this:
You upload a part drawing — the system instantly analyzes structural challenges, evaluates manufacturability, and gives DFM insights.
You click “quote” — it calculates material, process, and quantity in seconds, producing an accurate quotation.
You confirm the process route — it automatically generates standard work instructions, including step descriptions, tool lists, and safety notes.
This “Digital Old Chen” never takes a day off, never retires, and remembers every detail of every part your factory has ever made.
That’s what we call the Digital Engineer.

Why Generic AI Can’t Do This
Some might say, “Why not just plug ChatGPT into our data?”
Unfortunately, that doesn’t work in industrial settings.
Manufacturing knowledge isn’t just text — it’s multi-modal, rule-bound, and context-dependent.
It includes CAD models, process sheets, BOMs, and even PLC code.
That requires an AI that can:
Understand complex CAX data and technical drawings
Deliver absolutely accurate, deterministic answers
React to real-time shop floor data
Execute, not just “talk”—interact with MES, ERP, and scheduling systems
That’s why Leanplans’ Hybrid Expert Model is fundamentally different from generic large language models.
Our domain-specific multimodal AI is built for manufacturing.
It doesn’t just generate text—it interprets CAX models, process files, and equipment logic.
Every answer is backed by real industrial rules and verified process data.
Because our platform is system-level, it connects directly with your MES and ERP, forming a closed loop from decision → action → feedback.
Even better, it learns continuously from your own factory data—your standards, process rules, and production records—so it truly becomes your exclusive AI expert.
We’re not building a “chatbot.”
We’re building an AI Manufacturing Hub that operates like a team of expert engineers.
It can:
AI DFM Evaluation: Instantly identify manufacturability issues and design risks
AI Quotation: Generate accurate, reliable cost estimations in minutes
Automated Work Instructions: Cut documentation time by over 80%
Knowledge Configuration: Activate hidden knowledge assets and turn them into actionable expertise
This isn’t just about saving time — it’s about creating your own AI Expert Team.

Final Words
Today, 103 manufacturers have already started building their “Digital Old Chen.”
They’re no longer afraid of knowledge gaps or experience loss.
Their production knowledge now has a digital life.
If you’re also facing an “Old Chen is retiring soon” situation — now is the perfect time to digitize your process intelligence.
Join the global wave of AI-driven agile manufacturing today.
Let your factory’s experience, knowledge, and craftsmanship live on—forever.
