What is Quality Assurance? An Introduction to Quality Assurance

They also helped standardize the training for navies to make sure long sea journeys were as safe as possible. They seek to uncover and address the sources of quality problems, such as human error or a business using the wrong materials. Whereas the QC team is reactive, checking the product for mistakes or components not built to specification. Without QA and QC practices in sync, you risk launching a glitching product that attracts negative reviews, damages your brand reputation, and undermines customer loyalty.

Quality assurance explanation

This bolsters consumer trust and confidence in the business, and it helps the business compete with others in the same market. Very often, companies fall into the trap of thinking they have both QA and QC in place. They lack some significant aspects in their QA process such as compliance with quality management standards, test data adequacy, and knowledge transfer management. Life sciences organizations should “close the loop” on quality management processes by using QC to inform QA.


By streamlining processes and eliminating waste, quality assurance can help boost efficiency and productivity levels across your organization. This can save you time and money and free up resources for other priorities. Quality assurance can also help you develop training programs, implement process changes, and identify areas where team members need improvement.

Quality assurance explanation

It doesn’t deal with the processes used to create a product, instead examines the quality of the end product and outcome. Managing the quality of a product or service involves planning, fulfilling, and monitoring activities. It’s the process or act of confirming whether the firm’s quality requirements met or not. Noncompliance to the new price transparency requirements can lead make the business vulnerable to public disclosure and exposure of trade secrets. A cohesive strategy that focuses on value-based contracts (VBCs) by relating payment to its value is necessary and requires businesses to create a model that helps forecast and conduct scenario analysis for possible VBCs.

Statistical Process Control (SPC)

For example, the bank may set targets regarding the timings on how long it takes to answer consumers calls as well as support customers with an issue. And QC is product-oriented which means it focuses on the inspection of products. QA is process-oriented which means it focuses on the processes related to quality. Cause and effect diagrams, also called Fishbone or Ishikawa diagrams, require members to brainstorm and outline all the possible causes of a problem.

But most of them get confused to pin down the differences between quality assurance, quality control, and testing. Senior quality engineers earn the best pay in the professional Quality assurance vs. Quality control industry, where they command an average salary of $100,740. Quality assurance supervisors earn the highest pay from the health care industry, with an average salary of $80,377.

Quality Assurance Roles and Responsibilities

Quality assurance (QA) standards are a set of measures implemented by businesses worldwide to confer commitment to delivering quality products or services to their customers. Mainly, QA standards are about meeting customer requirements that exceed their expectations. Quality assurance is often confused with quality control (QC), another component of a quality management system. A quality management system is a set of methods and tools that lets organizations manage all aspects of quality management including quality planning, quality assurance, quality control and quality improvement. QA involves the design of processes, such as documenting standard operating procedures (SOPs) according to ISO 9000 standards. A safe, effective product should be the result every time processes are followed.

  • For comparison, quality assurance supervisors earn the highest salary in the health care industry.
  • It should be able to predict the financial impact and share it with a cross-functional team to understand the implications for the business.
  • Auditors/quality tend to reach similar levels of education than quality assurance supervisors.
  • Within an organization, each department or unit also may be in different stages.
  • As the name suggests, this stage allows the implementation of the processes identified in the previous phase.

A portion of careers in SQA include job options like SQA engineers, SQA Analyst and SQA test automation. An SQA Analyst will monitor the implication and practices of SQA over software development cycles. SQA test automation requires the individual to create programs to automate the SQA process. The ISO (International Organization for Standardization) is a driving force behind QA practices and mapping the processes used to implement QA. Many companies use ISO 9000 to ensure that their quality assurance system is in place and effective.

Quality-centric Companies Rely on CQ QMS

There are several types of quality assurance testing, all of which are important for ensuring your product is bug-free. Below, we’ve listed the primary QA testing methodologies to give you a complete understanding of the testing process and how it improves your software, app, or product. After executing the quality audit and analysis, the next step would be to introduce the recommended changes in project processes through a project review process. The concept of quality assurance was first started in the manufacturing domain and later spread to most of the industries, including software development.

Quality assurance explanation

It involves monitoring and evaluating processes, providing feedback, and implementing improvements in order to maintain and enhance the quality of products or services. IQA is typically carried out by a team within the organization responsible for quality assurance, and it focuses on continuous improvement through feedback and corrective action. Quality assurance (QA) is a systematic process that ensures products, services, or processes meet or exceed established quality standards. It involves activities and techniques aimed at preventing defects, identifying and resolving issues, and improving overall quality throughout the entire lifecycle of a product or service. Quality assurance aims to ensure consistent and reliable performance, customer satisfaction, and compliance with regulatory requirements.

By improving the performance of your teams, you can improve the quality of your product while reducing costs. Quality assurance uses a quality system that is set up to implement administrative and procedural tasks, which create goals for the product or service of the project. This provides a systematic measurement and comparison with a standard, along with a monitory of processes and a feedback loop to make sure no errors pass through production. A quality manager is involved with all areas of a quality management system.

Quality assurance explanation

Unlike unit testing, which focuses on an individual unit, integration testing is all about checking how units work together to complete functions. Like unit testing, integration testing can be a slow, repetitive process. QA teams often automate the parts of the integration testing to improve efficiency and save time. Finally, quality assurance audit activity generates formal documentation of required changes to the execution process and acts as a base for formulating corrective actions. Consultants and contractors are sometimes employed when introducing new quality practices and methods, particularly where the relevant skills and expertise and resources are not available within the organization.

QA career paths

Quality Control should come into play once the product is complete (or when it’s already on the market) to ensure that it works as expected. Both QA and QC activities have a vast impact on all of the above characteristics. But QA ensures software quality by enhancing processes, and QC — by improving a product. Non-conforming test results should result in corrective and preventive action (CAPA) investigation to determine the root cause of quality issues and update processes to prevent the problem from happening in the future.
