Not trained
The technician does not work on the technique. Useful for sizing the training need and the dependency risk.

The skills matrix: map to make reliable.
Who can do what, on which instrument, with what level of autonomy? In the quality control laboratory, this question often goes unanswered. The skills matrix answers it — and reveals where the gaps that generate errors and OOS are hiding.
Who · What · Autonomy
A QC laboratory relies on dozens of techniques and systems — HPLC, GC, Karl Fischer, UV, LIMS… The matrix cross-references each one with each technician.
The skills matrix is a simple but powerful table: technicians in rows; techniques and systems in columns; a status at each intersection. It turns a vague feeling ("the team is skilled") into an objective map of strengths and weaknesses — the prerequisite for managing reliability seriously.
The real problem
"Trained" does not mean "autonomous."
A checked-off training record does not guarantee real mastery of a technique. Without a clear distinction between not trained, trained but not autonomous and trained & autonomous, critical analyses get handed to people who are still learning — and the problem is discovered after the fact, through an OOS. The matrix makes this nuance visible, workstation by workstation.
Three statuses
A level of mastery, not a checked box.
Trained, not autonomous
Still learning: they operate under mentoring or double-check. The riskiest status if mistaken for autonomy.
Trained & autonomous
Qualified, they operate alone and can mentor others in turn. The goal to reach, critical technique by critical technique.
What it reveals
Four readings, four decisions.
Fragile techniques
A column full of "not trained" flags a technique that depends on one or two people: a continuity and error risk.
Exposed people
A row light on autonomy — often a recent hire — points to high exposure to error and OOS.
The "key-person" risk
A critical technique mastered by a single expert: what happens if they leave or fall ill?
The upskilling plan
The matrix becomes an action plan: who to train, on what, in what order — prioritized by criticality.
The logical next step
From the map to the learning path.
A matrix is only worth something if it triggers action. Every "not trained" or "not autonomous" cell on a critical technique calls for a qualification path: concepts, mentored practice, supervised routine, then formal validation of autonomy. The matrix steers, the path trains, qualification proves — and analyst error goes down.

The skills matrix in practice.
It's a table that cross-references technicians (in rows) and analytical techniques or systems (in columns), with a mastery status at each intersection: not trained, trained but not autonomous, trained and autonomous. It objectifies the team's real skills.
Because a recorded training does not prove mastery. Conflating the two means handing critical analyses to people who are still learning — a direct driver of error and OOS. The distinction lets you supervise (mentoring, double-check) until autonomy is qualified.
It reveals fragile techniques, exposed people and "key-person" risks, and turns into an upskilling plan prioritized by criticality. By targeting training where the risk is real, it prevents analytical errors at the source.
By embedding it into day-to-day management: update it at every qualification, arrival or departure, and review it regularly. Paired with a skills-management platform, it stays alive and provides traceability that holds up in inspection.
