A quality audit is a procedure in which a team of auditors, either internal or external, thoroughly examines a quality system. It is a key component of the ISO 9001 quality system standard. Audits are needed to determine whether newly adopted or existing processes, products, and systems successfully deliver the greatest benefit to a business or organization. It is an important feature of any organization's quality management system and is widely used in many industries.

In the manufacturing world, quality audits are an effective way to check that your company or your vendors’ manufacturing activities are meeting your product quality standards. It is also used to check for conformance to your defined QMS quality system rules and guidelines.

The American Society of Quality (ASQ) is the recognised authority on best practices in quality audits and many professional auditors obtain ASQ quality auditor certifications. In general, a quality audit focuses on evaluating the system's performance through an unbiased, systematic and documented process. The auditor evaluates the data and assesses the findings in terms of how well the system or process under audit is working.

Here we'll go into details of quality audits, examining what they are, their types, importance, the steps involved, and how your organization’s manufacturing or sourcing activities may benefit from them.

Why Conduct Quality Audits?

For companies with product manufacturing, engineering, supply chain, or sourcing activities, quality audits are essential for the following reasons:

  • Ensuring Compliance: Audits confirm that a company complies with all internal policies, rules, and applicable quality standards.
  • Continuous Improvement:They help organizations improve their systems and processes by pointing out areas that still need improvement.
  • Risk mitigation: Audits assist in identifying and reducing risks and deviations from recognised standards of quality.

If you are working with external vendors, manufacturing partners, and contract manufacturers, quality audits are a key method of benchmarking their performance against your QMS and quality requirements.

Types Of Quality Audits

What is being audited determines the type of audit. Although there are many different types of quality audits, process, product, and quality system audits(QMS) are the three main categories. We'll go into more depth of these categories.

Process Audits

The purpose of this audit is to determine whether a company's procedures adhere to established regulations (such as FDA GMP) or industry standards (such as ISO). By comparing the company's procedures, work instructions, training logs, job descriptions, etc. to the established standards, the auditor will evaluate the process controls. Process audits can be carried out on all of the quality system's processes or just a few of them.

Product Audits

This specific kind of quality audit looks into whether a certain good or service (hardware, processed goods, or software) meets with performance standards or customer needs. To determine whether the product complies with desired product requirements, it will be assessed against performance standards, product specifications, and most probably customer requirements. Product audits are typically carried out during or just after the production process.

Quality System Audits

This particular type of quality audit will make sure all components of a quality management system (QMS) have been developed, put into practice, and documented in accordance with the necessary specifications and international best practices as defined by the ISO 9001:2015 Quality Management System Standard. By comparing procedures and policies, the auditor will assess the company's quality system to identify conformance levels. Quality professionals recommend that quality management system (QMS) audits must be performed at least once in a year.

Key Components Of A Quality Audit

These are the key areas of a quality audit:

Audit Criteria

The standards, laws, and other requirements against which the audit is conducted.

Audit Evidence

The facts and information gathered throughout the audit process to substantiate conclusions.

Audit Findings

Observations, non-conformities, and areas for improvement are all included in the audit findings.

Corrective Actions

Actions taken by the organization to address discovered non-conformities and stop them from repeating again are known as corrective actions.

Quality Audit Process

To further understand what is a quality audit, let's have a look at the quality auditing process.

Audit Initiation

Starting the quality audit is the first step in the audit process. To initiate a quality control audit, the customer, the auditee, and the auditing company or auditor have to first communicate with one another so that the audit objectives are fully understood. This forms a point of reference to design the audit framework and parameters

Audit Planning

The auditing company’s or auditor’s planning for the audit includes a number of activities from the three parties involved in the audit, such as scheduling the audit, estimating the amount of resources required for the audit, and preparing the audit questionnaire.

Audit Execution

Following the quality audit planning, the auditor begins a number of tasks, such as assessing system and process controls, interviewing stakeholders, reviewing technical processes, and doing documentation reviews. These tasks are conducted according to the audit parameters.

Audit Reporting and Follow-Up

The auditor puts together a report of audit findings. The audit report contains performance assessments against the audit criteria and provides independent insights into how the auditee company addresses quality management in their organisation.This report enables an organization to efficiently monitor performance and quality, identify areas for further improvement, and highlight any successes.

Who Performs Quality Audits?

Depending on who conducts the audits and what the audits are intended to achieve, there are distinct audit types.

This image depicts Who Performs quality Audit
  • First Party audits

    First party audits are internal quality audits because no outside parties are involved; they are carried out by auditors who work for your company. As stated, for the audit to be unbiased, the auditor will not have a personal stake in the outcome. This could be an official audit to measure corporate objectives, uncover gaps, or find possibilities for improvement, or to establish whether the organization is ready for an external audit. The audit can focus on a single process, a whole quality system, a specific set of procedures, or even a specific good or service. A prime example would be your quality manager checking the efficiency of the quality procedures in your purchasing department.

  • Second Party Audits

    Second party audits are referred to as external quality audits because they are carried out by someone outside of your organization, but they are typically connected to you in some capacity, such as a service provider. The scenario could possibly be reversed, you being the one assessing your contract manufacturers or suppliers to learn more about their quality assurance. Due to the possibility that they may influence future business choices, these audits are more important than internal quality audits. A good example would be a new client analyzing your full quality management system to determine its efficacy and whether they want to work with you.

  • Third Party Audits

    Third-party audits are performed by someone outside of your organization to ensure that applicable standards are satisfied, so they are also regarded as external quality audits. The auditors are impartial and have no personal or financial stake in your company. This is crucial since the outcomes of the audits could lead to certification or license approval, or they could have the opposite effect and lead to warning letters, penalties, fines, or prohibitions. A prime example would be a notified body auditor visiting your business to conduct an ISO audit, which should lead to your business being certified to an ISO standard.

Why Is Quality Auditing Important?

Quality auditing can add significantly to a company's worth and helps to create a ‘quality first’ culture in your organization, suppliers, and supply chain.

The process can:

  • enhance both the system's and the product's quality;
  • evaluate the cost-effectiveness of quality systems;
  • quantify the effectiveness of quality programs;
  • boost productivity by ensuring that product output is more uniform, minimizing errors, reducing resource and labor waste; and
  • provide employees with a platform to report deficiencies in the interpretation of the most basic quality requirements.

What Are The Advantages Of A Quality Audit?

Regular quality audits in your organization have a lot of advantages. Here is how they can help your company. Quality audits:

  • Ensure better quality of products/services
  • Enable the organization to remove inefficiencies
  • Improve focus on quality metrics
  • Help to improve employee performance
  • Provide measures for corrective actions for nonconformities

What Is A Quality Audit Checklist?

A Quality Audit Checklist is a tool that assists auditors, quality managers, inspectors, or a designated person in auditing products or operational processes.It aids in evaluating how effectively established quality control processes are working and in identifying any underlying problems that call for correction. Regular quality control audits can drive good product quality management practices, increase business efficiency, and enhance corporate strategies while still adhering to current requirements

Quality audit checklists are written according to the company’s audit objectives and may have specific technical areas that need to be reviewed for quality performance. The ISO 9001:2015 Quality Management System standard is often used as a guide for the key areas the quality audit checklist should cover. We have summarized these as follows:

Documentation and Procedures

  • Making sure that there are formal, documented quality controls in place.
  • Make sure that the procedures are current and the organization’s personnel can access them
  • Verify that staff members comply with specified procedures
  • Look for any documented violations of protocols and how they were fixed.

Quality Control and Testing

  • Review the documentation of the testing and quality control processes
  • Make that the testing equipment is maintained and calibrated
  • Make sure all products go through proper quality inspections and in-process quality controls
  • Assess how non-conforming products are handled and disposed of

Supplier Quality Management

  • Review the selection and approval processes for vendors.
  • Look for documentation of supplier audits and reviews
  • Verify that incoming materials adhere to quality standards
  • Examine the procedures for addressing and managing lower tier supplier non-conformities

Employee Competence and Training

  • Check to verify that employees are properly trained in quality practices.
  • Make sure to keep track of employee training and competency evaluations.
  • Verify that staff members are aware of their responsibilities for ensuring quality

Remedial and preventive measures

  • Review the procedures or finding, reporting, and addressing non-conformities.
  • Examine the documentation of corrective and preventative activities implemented.
  • Evaluate methodologies used to identify the root cause of quality problems or non-conformities.
  • Make careful to conduct root cause analyses for serious issues.
  • Check the success of corrective and preventative measures.

Auditing and Internal Assessments

  • Verify that measures are made to fix issues and audit reports are documented.
  • Verify that qualified employees are conducting audits.
  • Examine the success of earlier corrective measures brought about by audits.

Management Evaluation

  • Check the frequency and information contained in management evaluations.
  • Analyze the level of top management participation in activities related to quality control.
  • Verify that decisions for improvement are made as a result of management evaluations.

Quality Assurance Audit And Quality Control Audit

Both QC audits and QA audits utilize the same auditing process used by auditors to determine if products, production processes, and management systems adhere to predetermined criteria.

Only In-House Auditors Can Perform Quality Control Audits -No

The statement that only internal auditors can perform quality control audits is wrong. Both internal and external auditors are able to perform quality control audits. The choice of using internal or external auditors is based on the particular requirements and conditions of the organization.

Major Reasons For Quality Audit Failures

  • Unskilled auditor team
  • Misunderstanding of audit framework and requirements
  • Poor participation from the auditee and poor information provision e.g. managers are not available for audit interviews, lack of documents for review.
  • Audit assessments are not rigorous enough
  • No clear audit objectives
  • Not enough resources

Quality audit failures can be prevented by having professional auditors who have strong investigative skills, technical knowledge, and experience in conducting quality audits within the manufacturing and engineering contexts. They should also have engineering backgrounds - it’s important to check this carefully because many quality auditors may have more of a finance or business background. Being clear about the audit objectives and requirements, having a good audit checklist, can go a long way in ensuring the audit is a success.

A quality audit enables organizations to enhance their overall efficiency, effectiveness, and commitment to delivering products and services that meet or exceed specified quality standards. So if you haven’t done a quality audit yet in your company or on your suppliers, now’s the time to get started!
