Deviations

Deviation handling is the most-read part of a quality system, because it shows an inspector how the site behaves when something goes wrong.

In one line

The question that decides the investigation is what else shares the same cause.

One GMP problem. Multiple perspectives.Roles that genuinely see this differently — not the same text with the job title changed.

Deviations from five GMP roles

QA

Quality assurance and the system as a whole

Is the cause confirmed, and is impact assessed beyond this batch?

Impact should cover other batches sharing equipment, materials, personnel or time window. That second half is the part most often skipped.

QC

Laboratory, testing and analytical data

Does the laboratory data support the conclusion?

Where the event involves a result, the analytical record needs to be examined in its original form rather than as a summary.

Manufacturing

Production, process and the floor

Why did the process permit this?

Ambiguous instruction, layout, workload, or a control depending on vigilance rather than design. Open deviations also gate release, making closure a throughput constraint.

QP

Certification and batch release

Can the affected batch be certified, and on what basis?

The assessment and its rationale must be documented; a certified batch with an open significant deviation and no recorded reasoning is a serious finding.

Regulatory

Requirements, dossier and authority expectations

What does our cycle time say about control?

Investigation cycle time is read as a proxy for whether the quality system is under control, and the data is in your own registers.
