Quality control · Risk analysis

Streamline QC controls through 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.

Observed at a French pharmaceutical contract manufacturer (CDMO), 2023 → 2024.

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

Three risk indices, one decision.

Delegating or streamlining a control rests on the combined assessment of three levels of risk.

1

Supplier risk

Approval status, audit history and results, product conformity, administrative reliability, criticality of the material supplied.

2

Item risk

Severity (active ingredient, excipient, packaging), OOS history, batch volume, method complexity and overlap with the supplier's testing.

3

Test risk

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

From overall risk to action.

Combining the three risks points to a clear decision — traceable and defensible under inspection.

Supplier Item Test Decision
LowLowLowDelegate the test and/or reduce frequencies
LowLowHighDelegate if the supplier masters the method (targeted audit)
LowHighLowDelegate the tests already performed by the supplier
HighLowLowFirst improve the supplier's status
HighHighHighDo 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

43 items, three pools.

Analyzing the critical items reveals where to act first — and where control must stay in-house.

8%
of the workload: low risk → immediate delegation (quick wins).
56%
moderate risk → improve the supplier's status: the real pool.
36%
high risk → control kept in-house, no compromise.

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.
