How We Built a Repair System That Doesn't Depend on Individual Experience
Designing an SOP-based operation that maintains quality even as teams grow.
Every repair center eventually faces the same challenge.
At the beginning, experienced technicians can solve almost every problem through their own skills and judgement.
But as the business grows, relying only on individual expertise becomes increasingly difficult.
The TERRA RING project gave us an opportunity to rethink how a repair organization should be built.
Instead of designing a repair center around talented individuals, we decided to design a system that allows quality to remain consistent regardless of who performs the work.
Many of the operational principles developed during this project later became the foundation of AXION HUB’s service management philosophy.
1.Why Experience Alone Was Not Enough
Great repair quality should not disappear when one engineer leaves.
When the TERRA RING project began, repairs were performed mainly by experienced engineers.
This approach worked well while the team remained small.
However, we quickly recognized several limitations.
If repair quality depends entirely on one person’s experience, training new engineers becomes difficult, knowledge is hard to transfer, and consistent quality becomes impossible as the organization grows.
We wanted a repair system that could continue operating even if individual engineers changed over time.
Instead of asking people to memorize everything, we decided to document every important process and convert technical experience into standardized procedures.
This became the starting point of our SOP system.
2. Dividing Repair Work into Three Independent Processes
Complex repairs become manageable when responsibilities are clearly separated.
To make operations easier to manage, we divided every repair into three independent stages.
Inspection
↓
Repair and Assembly
↓
Quality Control (QC)
Each stage has its own responsibilities, records and verification procedures.
This structure allows every engineer to focus on a specific objective while ensuring that every product is checked multiple times before leaving the repair center.
More importantly, it prevents quality from depending on a single individual.
This workflow later became one of the core concepts behind our internal operating standards.
3. Separating People from Processes
A scalable organization depends on systems, not heroes.
The purpose of separating repair stages was not simply to divide work.
Each process requires different skills.
Inspection focuses on identifying problems accurately.
Repair focuses on technical execution.
Quality Control verifies whether every repair meets the required standards before shipment.
By assigning clear responsibilities to each stage, engineers can develop expertise without needing to master every task immediately.
This also makes training significantly easier and allows the organization to expand without sacrificing quality.
Our objective was never to create “indispensable technicians.”
Instead, we wanted to build an organization where quality is maintained by the system itself.
4. Building a Workflow Instead of Individual Tasks
Information should flow through the organization as smoothly as products.
An SOP is more than a collection of work instructions.
It defines how information flows through the entire repair process.
From product reception to diagnosis, repair, inspection and shipment, every step generates records that become part of the complete service history.
Customer service can immediately check repair status.
Engineers can review previous repair records.
Managers can analyze quality trends and operational performance.
Instead of isolated tasks, every department becomes part of one connected workflow.
This way of thinking later became the basis of the cloud-based service management system that AXION HUB is currently developing.
5. A System That Works Across Different Locations
Distance should never become a barrier to quality.
Another objective was to build a repair operation that would not depend on physical location.
Information should move faster than products.
Customer support can communicate with engineers even if they are working in different offices.
Repair records, photographs, shipping information and quality reports can all be shared through the same operational system.
Whether a product is handled in Osaka or Shanghai, the workflow remains consistent.
This principle continues to influence the way we design our current service platform.
6. Why These Ideas Still Matter Today
Good operational principles remain valuable long after a project ends.
The TERRA RING project itself eventually came to an end.
However, the operational concepts developed during the project did not.
Many of the same principles were later applied to projects for international brands such as Profoto, while continuing to evolve with new operational requirements.
The software systems have changed.
The repair environments have improved.
The management tools continue to evolve.
But the underlying philosophy remains the same.
Reliable after-sales service should be built on repeatable systems rather than individual experience.
That philosophy continues to guide the way AXION HUB designs repair operations today.
Key Takeaways from This Project
ome projects build products. Others build better ways of working.
• Experienced engineers are essential, but experience alone is not a scalable business model.
• SOPs should preserve organizational knowledge, not simply document procedures.
• A repair center is not just a collection of technicians—it is a connected operational system where people, processes and information work together.
