Every engagement closes with a detailed non-conformity report, root cause analysis and corrective recommendations.

My practice.

Inspection that traces back to the source.

The approach

From detection to prevention

The aim is not to sort pieces, it is to stop the defect coming back. Inspection happens at every stage of production and on incoming goods. Every non-conformity found opens onto something wider: understand where it started, adjust the process, prevent the repeat.

  1. Detect
  2. Understand
  3. Prevent

The deliverables

Detailed non-conformity reports

A document built around each non-conformity, with visual record, precise technical description, analysis and recommendation. A deliverable that travels between the bench, management and the end client, and becomes a shared language.

Extract from a non-conformity register (ISO 9001)

The extensions

Beyond production inspection

Incoming inspection of supplier deliveries, before manufacturing starts. Direct interface work as well: setting inspection conditions, specifying tolerances, explaining requirements on the supplier side, escalating points of disagreement. Gemstone control backed by gemmological qualification (FGA).

I would rather build dialogue between the workshop and the client than hand down penalties.

What I see.

In jewellery manufacturing, quality is invoked everywhere and built rarely. The departments exist. The certifications pile up. So do the procedures. And still the gap holds, between what the documentation describes and what actually happens at the bench.

The problem is not a lack of rigour. It is the absence of a system that produces quality by construction, instead of catching it at the end of the line. The distance between the maison as it imagines itself and the maison as it runs.

Most manufacturers think they have a procedures problem. Almost always, what they have is a dialogue problem between the bench and management.

That gap is the one I come to close.

How I read a workshop.

Five axes that structure my observation, in inspection as in structuring.

understand before structuring, structure before documenting, document before the conversation starts.

  • How many of your procedures are actually followed, exactly as written, at every bench?
  • When did you last watch an operator work for twenty minutes without stepping in?

    Reading

    Understand how the organisation actually works before prescribing anything.

  2. F2

    Standards

    Translate ISO 9001 requirements into concrete, workable constraints.

  3. F3

    Steering

    Build the indicators that let you see it coming.

  4. F4

    Savoir-faire

    Capture the craft without freezing it. Documents that serve the bench.

  5. F5

    Workshop-to-management dialogue

    Create the conditions for what the floor knows to reach management without friction.
