Comparing samples from several suppliers fairly

Compare supplier samples against the same essential requirements using the same methods and conditions where practical. Record what each item demonstrates, and keep a missing result separate from a failed one. Decide which product versions meet the brief before weighing the wider supplier offers.

Establish a common basis

Confirm which brief and version each supplier received. For every sample, record supplier, model, variant, date and stated deviations. A catalogue item and a customised prototype may both be useful candidates, but identify their different states before comparing results.

Use acceptance criteria set before inspection. Check each item with the same tool, method and reference where practical. If the method must differ, record why and do not present the results as directly comparable. Plan any destructive or specialist testing separately, including the samples and competence it requires.

Record results and gaps

A comparison matrix can make the decision visible:

These are empty illustrative columns, not findings about suppliers. Enter observations and document references rather than scores alone. Use not checked when a check could not be performed. Use failed when an item was checked against a stated criterion and did not meet it.

If a supplier offers a changed variant after the comparison begins, record the change and decide whether the affected checks need repeating. Apply any revised criterion to every candidate it affects, and record the reason for the revision.

Check what the proposed order would contain

Ask whether the sampled materials, components and process are those proposed for production. A hand-finished prototype may show a promising design while leaving production match open. Record the differences and the evidence needed for the production version.

Keep commercial terms beside the technical results without treating them as sample findings. Record the quoted quantity, included items, timing and work left to your business.

Australian business guidance considers price, reliability, delivery and quality in supplier selection. A sample review provides evidence about the product features checked; it cannot establish future supplier reliability or the full value of an offer.

For consumer goods intended for Australia, assess applicable safety requirements for each proposed product version. A visual comparison does not establish compliance. Check whether a test report for one sample or variant covers another before relying on it.

Key Considerations for Australian Supplier Selection

Make a bounded choice

Identify candidates that meet essential criteria, those needing a corrected sample and those with an evidence gap. Then state what additional evidence could change the decision. For instance, you might accept a sample's appearance while holding its material decision for suitable evidence.

Keep the matrix, sample identifiers, criteria and decision together. The result should explain why a candidate remains suitable for further approval, rather than turn an attractive sample into a promise about production goods.
