Do you know who Sherlock Holmes is in the business world? Yes! Quality Auditors. The enigmatic people who have an eye for detail in checking the quality of products and services by different companies. These inspectors are like guardians of excellence as they check every piece of product for optimal standards and are behind the scenes of every top-notch operation. 

Here, we will go through a thorough yet interesting detail that covers all about quality auditors- including ‘what is a quality auditor?’, roles and responsibilities, job description, skills required to become one, and career prospects. 

What Is Quality Auditing? 

Quality auditing is the process of monitoring and improving all aspects of a quality management system (QMS) through an impartial and systematic inquiry, assessment, and evaluation.

The goal of a quality assurance audit is to determine whether an organization is following the principles and regulations prescribed by the supervisory regulatory body and, more crucially, consumer expectations. 

The Goal Behind Carrying Out Quality Audits 

A quality audit's main goal is to evaluate a business's quality management system's efficacy and compliance with specified standards, laws, and best practices. The procedure serves important functions: 

  • Regulation: Quality audits ensure a business or organization follows applicable laws, regulations, and industry standards. 
  • Quality assurance: Quality audits help ensure that the company continuously provides clients with high-quality goods or services by methodically assessing procedures and systems.
  • Building client satisfaction: Improved customer satisfaction and loyalty are the outcomes of consistently providing high-quality goods and services that result from small, continuous improvements through quality audits.
  • Data-driven decision-making: The results of audits offer useful information and uphold data integrity, which guides future planning, resource allocation, and strategic decisions.
  • Risk reduction: Audits enable preventative action to lessen the impact of risks by identifying possible hazards and weak points in a manufacturer's systems and processes.
  • Continuous improvement: Quality audits serve as a spark for continual process innovation and refinement by pointing out opportunities for improvement.

As a result, a quality audit serves a double function of ensuring standards are met while encouraging ongoing improvement inside an organization.

Types of Quality Audits 

ISO 19011:2018 defines auditing as a "systematic, independent and documented process for obtaining audit evidence [records, statements of fact or other information that are relevant and verifiable] and evaluating it objectively to determine the extent to which the audit criteria [a set of policies, procedures or requirements] are fulfilled."

The type of audit conducted depends on the subject being audited, which can be broadly categorized into process, product, and system audits. 

Process Audits

In this audit, a quality auditor checks whether a company's processes follow predefined standards, like the FDA GMP or ISO. As a result, a process audit ensures that processes operate within set parameters.

A certified quality auditor examines the process controls by comparing the company's processes, work instructions, training records, job descriptions, and other documents to the set standards. Process audits can be performed on the complete quality system or specific processes.

The following are what a process audit may cover:

  • Resource Examination and Performance Metrics Analysis: Examine the resources (equipment, materials, and people) used to change inputs into outputs, as well as the environment, processes, and performance metrics.
  • Standard Adherence Assessment: Check for commitment to established standards such as time, precision, temperature, pressure, composition, responsiveness, amperage, and component mixture.
  • Process Control Evaluation: Assess the adequacy and efficacy of process controls developed through procedures, work instructions, flowcharts, training, and process specifications.

Product Audits

Within this type of quality audit, a quality auditor checks if a certain product or service (whether hardware, processed material, or software) meets customer or performance standards. The product will be tested against product specifications, norms of performance, and, most likely, customer requirements to see whether it meets the required product specifications. Product audits are typically performed close to or at the end of the production process.

System Audits

This particular type of quality audit checks that all parts of a quality management system are effective and have been established, implemented, and documented in accordance with the set standards. The auditor will evaluate the company's quality system to verify compliance by comparing processes and policies to regulatory standards and additional contractual commitments. 

Therefore, it consists of the overall regulatory requirements that the business has set and the mutually agreed-upon obligations outlined in contracts between the business and its clients. System audits should be performed at least once a year. An assessment of a management system is done. An audit of the quality management system assesses if the current program satisfies legal requirements, corporate standards, and obligations under contracts.

What Does a Quality Auditor Do?

A certified quality auditor has auditing processes training and qualifications.

  • Guarantees accurate performance following business protocols.
  • Has no direct control over the topics being audited; otherwise, there would be a conflict of interest.
  • Guarantees an impartial and equitable audit assessment and final report.

First-party internal quality audits typically only reveal a problem when insufficiently qualified persons cannot audit the quality department's processes. However, this can be readily fixed by providing someone outside the quality department with further training.
