A quality audit at a manufacturing company – how to prepare for it?

quality audit at a manufacturing company

Key information

  • A quality audit evaluates entire processes and organizational solutions, unlike routine quality control, which focuses exclusively on inspecting finished products.
  • Effective plant preparation involves six key steps: defining the scope of requirements, reviewing the currency of documentation, inspecting processes at workstations, verifying certifications and training, conducting an internal audit, and efficiently resolving any identified nonconformities.
  • The most common mistakes made prior to an audit stem from a lack of consistency, which leads to hastily gathering documents at the last minute, missing training certificates, outdated instructions, and discrepancies between theory and practice on the production floor.
  • The auditor’s discussions with employees at their workstations are a key element of the verification process, allowing for an assessment of their actual knowledge of procedures and guidelines for handling problems.

There’s one week left until the company’s quality audit. Before the auditor’s visit, we need to check that the manuals are up to date, compile the documentation, verify training records, and ensure that employees are familiar with the applicable procedures. The problem is that some of the documents are stored in binders, and training records were entered late. How many people will be assigned to organize the documents? How will this affect operations? And does preparing for a quality audit at a manufacturing company always have to be this way? Find out what a quality audit in manufacturing entails and how to prepare your facility to avoid a last-minute scramble to catch up.

What is a quality audit in a manufacturing company?

A quality audit is a systematic, independent, and documented assessment of whether processes, work practices, and results meet the requirements set forth in standards, the organization’s internal procedures, or agreements with clients.

An audit at a manufacturing facility is not limited to reviewing documentation. The auditor may also observe operations on the production floor, speak with employees, conduct interviews using a checklist, and verify whether the practices in place comply with applicable instructions.

Depending on the purpose of the audit and the entity conducting the assessment, the following categories are distinguished:

  • internal quality audit – conducted by an organization or on its behalf, used to assess the compliance of processes and identify opportunities for improvement;
  • external quality audit – conducted, for example, by a client, a certification body, or another external entity.

It is important to distinguish between a production audit and ongoing quality control. Quality control focuses primarily on inspecting products and their specifications, while an audit also evaluates processes and organizational solutions.

What areas might be reviewed during a quality audit?

The scope of a quality audit depends on its purpose, the type of production, and the criteria adopted. The areas most commonly verified are:

  • documentation – the existence, accessibility, and up-to-date status of procedures, job instructions, health and safety guidelines, and other documents;
  • production processes – compliance of performed activities with established standards;
  • competencies – qualifications, required skills, and certifications;
  • training – training programs, dates, and certificates of completion;
  • quality documentation – inspection results, forms, records, and reports;
  • nonconformities – methods for identifying problems and taking corrective actions;
  • previous audits – implementation of recommendations and effectiveness of implemented actions.

How to prepare your company for a quality audit, step by step?

A production audit includes both administrative checks related to documentation and verification of the plant’s actual operations. How should a company prepare for a quality audit?

What mistakes should you avoid before a quality audit?

What does the period right before a quality audit look like in most manufacturing companies? Everyone is in a panic—which is no surprise if there hasn’t been any regular internal oversight up to that point.

The quality department starts going through the files and discovers that some of the instructions are out of date, while certain training certificates are nowhere to be found. The production manager has to determine whether all operators are familiar with the current procedures, and the HR department checks whether all required training and certifications are up to date.

All these backlogs must be cleared up quickly. Employees are pulled away from their duties, and documentation is completed in a rush. Production efficiency drops, and the risk of errors increases. The resulting decline in plant efficiency over several days may have fewer consequences than a negative audit result. However, by avoiding basic organizational mistakes, the company can avoid incurring such costs altogether.

The most common mistakes include:

  • outdated instructions,
  • lack of training certificates,
  • discrepancies between procedure and practice,
  • outdated certifications,
  • lack of corrective actions following previous audits.

Most of these errors can be easily avoided through systematic monitoring of documentation, competencies, and processes.
