How to prepare an operational audit

An operational audit starts before the site visit. Preparation helps everyone understand what will be observed, which information needs to be collected and how the results will be shared. A clear scope and agreed criteria make the records more useful for the people who will act on the findings.

Set the objective and boundaries

Start by writing the question the audit should answer. For example: “How is the goods receiving process being carried out at this site?” Identify the process, location, period and activities covered.

Record any exclusions as well. If the visit covers receiving but not storage, make that decision explicit. Agree which documents will provide the reference criteria and check that you have the current versions.

Turn criteria into observable checklist items

Each question should support a specific check. “Is the process well organised?” leaves considerable room for interpretation. “Is there a record of the incoming materials check?” gives clearer direction for observation and evidence collection.

For each item, prepare:

• The criterion to be checked.
• The possible answers and when “not applicable” is appropriate.
• The expected evidence, such as a record, photograph or observation.
• The context needed to interpret the answer.

Try the checklist against a small example before the visit. Unclear questions are easier to resolve while there is still time to adjust the template and brief the team.

Plan evidence and sampling

Decide which records and situations you intend to observe. If you use a sample, describe how you selected it and which period it covers. The conclusion should reflect what was actually checked.

Prepare a consistent way to identify the site, equipment, date and record reference. Collect only the information needed for the audit, and avoid including personal details or documents that have no connection to its purpose.

Assign responsibilities and prepare the visit

Confirm who will lead the audit, who will accompany the visit and who will make the documents available. Agree on timing, access and the arrangements needed to observe the work safely.

If internet access may be unreliable, check beforehand what is available on the device and how you will confirm synchronisation afterwards. CHECKZAI supports preparing work and completing checklists offline in supported workflows; checking that preparation before leaving remains an essential step.

Allow time to close the work

Finish by reviewing the records. Do the answers include enough context? Is the evidence readable? Can someone understand what happened and where from the finding alone?

Share the points that need clarification and agree who will follow up. Good preparation creates a clear basis for decisions, reports and corrective actions, while preserving the limits of the work performed.
