Thank you for reading.
Today’s topic is “Operational decisions when AI prescriptions contradict internal standards.”
In a previous post (Factory Digitalization Ver07. “Operational Discipline Determines the Success of AI Implementation”), I introduced a South African manufacturer that, before adopting AI prescriptions, first reinforced strict adherence to its internal operating standards. This foundation is essential for establishing an AI‑driven operational culture.
However, once AI prescriptions are introduced into real manufacturing environments, cases inevitably arise where internal standards and AI prescriptions contradict each other.
■ Why do AI prescriptions fall outside internal standards?
In theory, if operations are performed strictly according to internal standards, AI should only generate prescriptions within that range. But in reality, AI sometimes outputs values outside the company’s defined limits.
For example, for Product A’s pouring temperature parameter:
Internal standard: 1,380–1,395°C
AI prescription: 1,400–1,410°C
A clear discrepancy appears.
The reason is simple:
During actual operations, deviations from the internal standard occurred, and those “out‑of‑standard” operations happened to fall within the quality sweet spot. AI then learned from those data points.
This phenomenon is common across many factories.
■ The confusion that inevitably occurs on the shop floor
Internal standards must be followed
AI prescriptions must also be followed
But the two contradict each other
Operators do not know which one to prioritize
As a result, hesitation spreads and operations stall
This is the worst possible situation.
■ Therefore, companies must define rules before AI deployment
Before introducing AI prescriptions, companies must clearly define:
“When internal standards and AI prescriptions contradict each other, which one takes priority?”
This decision must not be left to operators. It must be established as an official company rule.
■ Visualizing contradictions through color‑coded dashboards
Internal standards and AI prescriptions should be displayed side‑by‑side with color coding on dashboards so that differences are immediately visible.
Internal standards: Blue
AI prescriptions: Orange
This visual distinction is essential for recognizing contradictions at a glance.
■ And the most important point
If the company decides that internal standards take priority, and defects occur as a result of following those standards, the operator is not responsible.
Operators simply follow the company’s rules. Responsibility for quality outcomes lies with the management that defined the standards.
Unless this “ownership of responsibility” is clearly communicated, operators will hesitate—and an AI‑driven operational culture will never take root.
🟦 Summary
AI prescriptions can contradict internal standards
The cause is often “out‑of‑standard operations” that happened to hit the sweet spot
Example: Pouring temperature 1,380–1,395°C vs 1,400–1,410°C
Color‑coded dashboards make contradictions visible
Companies must decide in advance which to prioritize
If internal standards are prioritized, resulting defects are not the operator’s fault
Clarifying responsibility is essential for establishing an AI‑prescription culture
