Supplier risk
Approval status, audit history and results, product conformity, administrative reliability, criticality of the material supplied.
Quality control · Risk analysis
When volumes rise, the quality control lab's workload explodes — and hiring isn't enough. Skip testing based on risk analysis lets you streamline the controls on raw materials (RM) and packaging components (PC) without weakening compliance. Here's the method, proven at a French pharmaceutical contract manufacturer (CDMO).
+56%
more control hours in one year, for only +34% more batches: QC workload grows faster than volumes. Impossible to keep up with a flat headcount.
Skip testing means spacing out or delegating certain incoming controls, based on a track record and a risk assessment. Done well, it doesn't loosen control: it concentrates the lab's effort where risk genuinely warrants it, and frees up capacity to absorb growth.
The real problem
We control everything, all the time — even what doesn't call for it.
Out of caution, many labs systematically re-test every batch of every material, regardless of supplier, track record or criticality. The result: a workload that swells with volumes, saturated technicians, batch-release times that stretch out — with no real gain in safety. The question isn't "should we control?" but "where does control actually add value?".
The method
Delegating or streamlining a control rests on the combined assessment of three levels of risk.
Approval status, audit history and results, product conformity, administrative reliability, criticality of the material supplied.
Severity (active ingredient, excipient, packaging), OOS history, batch volume, method complexity and overlap with the supplier's testing.
OOS history on the test, required equipment, method validation status and potential impact on the patient or on regulations.
Each component is scored on objective criteria and compared against an acceptability threshold. Combining the three yields an overall risk level — and a decision.
The decision grid
Combining the three risks points to a clear decision — traceable and defensible under inspection.
| Supplier | Item | Test | Decision |
|---|---|---|---|
| Low | Low | Low | Delegate the test and/or reduce frequencies |
| Low | Low | High | Delegate if the supplier masters the method (targeted audit) |
| Low | High | Low | Delegate the tests already performed by the supplier |
| High | Low | Low | First improve the supplier's status |
| High | High | High | Do not delegate: control kept in-house |
Simplified excerpt from the decision grid. Each case is documented and justified, item by item.
Where the workload hides
Analyzing the critical items reveals where to act first — and where control must stay in-house.
Key takeaway: the quick wins (direct delegation) represent only a small share of the workload. Most of the potential lies in moderate risk — where an effort on supplier qualification progressively unlocks the majority of the possible reductions.
