Quality Assurance vs Quality Control: The Key Differences

This resource incorporates both quality assurance and quality control into one single platform. The work done by QA personnel has a substantial impact not just on the quality control system and other quality management activities but on the aims of the entire organization. That’s why life sciences companies are always striving to develop and refine a culture of quality that permeates the entire enterprise. For example, in food production, the main goal of Quality Assurance is to ensure the performed process and prevent any defects during primary production. On the other hand, Quality Control is there to detect a number of possible hazards caused by microbiological growth, chemical or physical contamination.

During these audits, we have found interlocks and critical safeties not functioning properly. As the project progresses, QA should check where the project may be developing risk and ensure that the Quality assurance vs. Quality control right people are involved at the right time. From PM — a holistic perception of all parts of the project, an understanding of the timing, milestones, and iterations of the project life cycle.

Quality assurance vs. quality control: what is the difference?

Quality assurance control systems are the methods and procedures which are used to safeguard quality standards. Quality control systems measure parts, including the outputs of the system. In the medical industry quality assurance is highly important, as a mistake could lead to the loss of human life. Agencies are employed nearly everywhere, from hospitals to laboratories, to make sure their standards are in tune with the industry. A quality assurance specialist, as the title suggests, oversees the QA portion of quality management. He or she collaborates with the quality manager to ensure strategic alignment.

If QC testing uncovers quality issues, it should result in reactive steps to prevent an unsafe product from being shipped and distributed. Total quality management is a quality assurance approach that consists of developing a company-wide quality management mindset. With the two above principles in play, the goal is to make the product or service work correctly all the time through the management of project constraints. While the terms might cause some to believe the association between the two functions is adversarial, there isn’t an inherently antagonistic quality assurance vs. quality control relationship. Rather, they are complementary elements of a manufacturer’s overall quality strategy. In life sciences companies, both functions are reliant on a formal quality management system .

Securing High-Quality Product

This approach lets you solve problems and implement solutions in a defined way. Rejecting products that are not up to standards, returning materials, and reporting their findings to the quality assurance team. Sampling is the process of selecting a set of elements from a product lot. Since it is costly to do a QC assessment on each product, a product is randomly selected to test its quality.

  • Quality Assurance provides assurance that the quality requested will be achieved, whereas Quality Control is a procedure that focuses on fulfilling the quality requested.
  • The QC role is to verify the quality of all of these various items to ensure that you can safely and confidently distribute the product to your customers.
  • A QC professional inspects or tests products to ensure that they function as expected, that there are no defects that could cause injury, and that the products are ready to be released to the market.
  • The focus is on design and development to create efficient and reliable products.
  • Final cost reduction as mistakes are prevented at an early stage.
  • A defect once fixed cannot ensure that it won’t occur again, even if the root cause is found.
  • The best people to work on a process analysis team are those who work on the process daily.

The QA process makes sure that the quality of your products is uniform. Your QC team ensures that any defect discovered will not get to your customer. As a result of this, your customers will have no room to complain about the quality of your product since quality is maintained. Quality audits are a systematic, independent, and documented review and evaluation of an organization’s quality management system. It is done to determine whether quality activities and results comply with the arrangement that is needed to achieve the objectives.

What are the differences between quality assurance and quality control?

In statistical sampling, you select a random number of items from a batch and inspect them for defects and conformance issues. As another example, Austin Maxwell, the general manager of Maxwell Counters, was very concerned about his business when he noticed that quality was being affected. His company specializes in the fabrication, installation, and replacement of customized countertops.

Quality assurance vs. Quality control

QA can identify mistakes that QC cannot and QC can identify mistakes that QA cannot. QA is performed in parallel with the project but QC is performed when the final product is ready. There is a great deal of responsibility on the shoulders of the team responsible for quality control. The developers can confirm that the product is in accordance set by the customers. While there may be a team of QC professionals, they generally work alone when testing products. Each QC team member follows SOPs to test the specific products they have been assigned or to test specific parts of a product.

What comes first, QA or QC?

It also provides a Quality Control environment to ensure everything is done right and the product is top-notch. So if you’re a software tester or quality assurance engineer, TestSigma is perfect for you! Get started and see how it can improve your software testing process and product quality. For a person who has nothing to do with software development and testing, quality assurance and quality control seem to be the same thing.

Quality assurance vs. Quality control

QC includes activities that provide verification of the product for documented requirements. The QC engineer analyzes the test results and is responsible for identifying and eliminating defects in the project. In other words, they are responsible for the results of what the developers or QA Teams have done.

Similarities Between Quality Assurance and Quality Control

QC is the responsibility of specific personnel within the organization. These individuals must follow SOPs to perform QC product testing. Helps you create, share, and ensure the correct adoption of your business’s policies. Write processes that ensure the system is easy to install and maintain.
