Share your requirementsWho usually fills this role
Typically science graduates, B.Sc. in food technology or microbiology, or diploma holders. Test at hiring with a sampling and moisture test, a sensory exercise and a short question on records. Check carefulness, honesty about bad results and willingness to say no to production.
Skills ladder
Stage 1
New joiner
- Collects samples correctly and labels them
- Runs basic tests such as moisture, pH or weight under watch
- Records results in the lab register
Stage 2
Independent
- Runs routine tests and reads specifications
- Flags out-of-spec results and holds the lot
- Calibrates instruments as per schedule
Stage 3
Senior or lead
- Investigates failures and traces causes
- Supports audits and customer complaints
- Trains operators and juniors on sampling and sensory checks
Training path
First weeks
- 1
Lab safety and hygiene
The quality manager shows lab safety, waste handling and clean sampling. The joiner demonstrates each and signs the lab rules.
- 2
Sampling plans
A senior analyst shows how and where to sample raw material, batch and finished stock. The joiner samples under watch and labels carefully.
- 3
Basic tests
The senior teaches moisture, pH, brix or other relevant tests. The joiner repeats tests until results match the senior's.
First year
- 1
Records and specifications
The manager explains the specification and why records matter. The analyst fills sample registers and the manager checks for gaps.
- 2
Out-of-spec handling
The manager shows the hold-and-escalate steps. The analyst practises with a mock case, and the answer is reviewed.
- 3
Calibration
The analyst learns to check balances and thermometers on schedule. Calibration entries are reviewed monthly.
Towards senior
- 1
Root cause
The manager teaches simple cause-finding on a failure. The analyst leads one study with production and writes a short report.
- 2
Audit preparation
The analyst helps prepare records for a customer or certification audit. The manager reviews files before the audit.
- 3
Training operators
The analyst teaches line staff on sampling and checks. The manager checks that line checks improve.
Performance review
A weekly record check by the quality manager, a monthly review of results, holds and complaints, and a written half-yearly review.
What to measure
| Measure | How it is seen |
|---|---|
| Accuracy of test results | Repeat tests and comparison with the manager |
| Record completeness | Register audit |
| Handling of failures | Hold tags and escalation notes |
| Calibration discipline | Calibration log |
| Support to production | Line feedback on turnaround of results |
| Honesty | Review of any altered or missing entries |
Evidence to bring
- Lab register
- Out-of-spec reports
- Calibration log
- Sample retention record
- Audit file
Questions to ask in the review
- Which results did you find hardest to judge?
- Did production pressure you on a failed lot?
- Which instruments are unreliable?
- How are sampling plans followed on the floor?
- Where do records slip?
- What training would help you?
- What patterns do you see in failures?
- How can we speed up results without cutting steps?
Pitfalls
- Treating the lab as a clerical post with no training
- Letting production overrule hold decisions
- Not replacing worn instruments
- Rating on number of tests done
Questions about this role
Make the hold decision belong to quality with a clear escalation path to senior management. Record and review each override.
It helps. Many labs also train diploma holders carefully. Test practical skills at selection and check any regulatory needs with your adviser.
Repeat with both, check instrument and method, then standardise the method and retrain.
