Quality control (QC) is a methodical procedure used to ensure that a product or service meets specified requirements and standards. It involves systematic actions and measures to verify that a product or service being developed meets a business’s predefined criteria for quality.

Whereas quality assurance is focused on the processes involved in producing the output, quality control (QC) is more on the inspection of the quality of the products. This is performed by evaluating if they pass specific quality standards before being shipped out to customers. As both parts of the bigger umbrella of quality management, QC aims to catch deficiencies in quality while QA aims to prevent those deficiencies from even occurring.
Good quality assurance and quality control are two of the most important elements of a successful operation in various industries, such as manufacturing and engineering. Achieving, ensuring, and maintaining the quality of your goods and services are paramount to making your customers happy and keep them coming back.

ISO is the International Organization for Standardization, with a current membership of 165 countries or national standards bodies. It is the world’s leading authority and regulatory body for safety and quality standards in manufacturing and service.
ISO standards are specific criteria set by ISO to cover different aspects of business and manufacturing operations. To earn a coveted ISO standard certification, a company has to request and pass a third-party ISO audit performed by a national or regional certification body.
To date, ISO boasts almost 22,000 standards and certifications covering a wide variety of operational aspects. Below are some of the most common standards companies strive for:
ISO 9001:2015 – Quality Management Standard
Last updated in 2015, ISO 9001:2015 specifies the requirements for a company’s QMS (Quality Management System). It aims to assess an operation’s ability to consistently deliver high-quality products and services while meeting customer expectations and relevant statutory and regulatory requirements.
ISO 22000 – Food Safety Standard

ISO 22000 provides requirements for developing and implementing a Food Safety Management System (FSMS). This certification is a must-have for companies in the food processing and food service industries.
ISO 45001:2018 – Workplace Safety Standard
Last updated in 2018, ISO 45001 sets the international standard for Occupational Health & Safety (OH&S) Management Systems. Failure to comply can lead to incidents, cost overruns, and even lawsuits.
Other notable ISO standards include ISO 14001 (Environmental Management), ISO 17025 (Laboratory Testing), and ISO 13485 (Quality Management of Medical Devices).
Here are some general prerequisites to establish and execute quality control procedures efficiently:
Having a dedicated QA/QC Team composed of personnel with the proper credentials should be a priority. Before creating a team, consider the employee’s knowledge of your specific product/service along with prior experience in the same industry before they joined your company.
Quality teams must consider the current performance of their product and/or service, define a SMART goal, and then strive to eliminate all of the processes, steps, and obstacles that do not contribute to the achievement of said goal.
Aside from the ones mentioned previously in the article, there are many other quality assurance and quality control methods available today. While Six Sigma, Lean, and Kaizen offer generally applicable procedures for improving overall quality, using the right tools to implement these methods increases their effectiveness.
Consistently delivering high-quality products through processes that are at par with industry standards and looking out for ways to further improve quality control can help your business stay on top.
Involve all employees and gain their buy-in and commitment to adhere to the organization’s quality standards and processes. Conduct onboarding for new hires and refresher quality assurance training for tenured employees to help them understand that maintaining the quality of products and services is everyone’s responsibility.
Reinforce quality control procedures through regular quality checks and immediately address nonconformance discovered during internal audits. Implement production planning and control or production control techniques to further strengthen the quality control procedures.
Utilize automated digital recordkeeping to save time and ensure that internal checks are consistently recorded.
Conduct customer satisfaction surveys, review incident reports, learn from past mistakes in your organization and others in the business, and stay up-to-date with industry best practices.
Save time and maximize resources for quality control by using new technology such as sensors that automate monitoring of quality parameters and mobile auditing tools to record and analyze information that paper audit forms cannot capture.
Regardless of your QA method of choice, each has its own pros and cons.
