Learn more about functional vs non-functional requirements to set clear benchmarks for the product. Both Quality Assurance (QA) and Quality Control (QC) are terms many people use interchangeably. You can see the main differences between QA and QC are visualized in the “Quality Assurance VS Quality Control” infographic. One of the fundamentals of ISO-9001, “continuous improvement” also suggests that the progress concerning Quality Assurance (QA) never stops.

  • The goal is not only to remove an issue but also to avoid the same error again.
  • Having separate QA and QC experts brings clarity to the process and allows teams to focus both on short-term and long-term objectives.
  • The infographic “Quality Control VS Quality Assurance” below illustrates the main differences between the processes.
  • In fact, the QC engineer specialty is a subset of the QA engineer specialty.
  • Quality assurance and quality control are often used interchangeably, but they are two different processes taking place at different times.

They’re designed to save time while managing your quality and project development. In the healthcare and life sciences industries, quality processes like quality assurance (QA) and quality control (QC) are required by the FDA and ISO 9000. They’re essential for regulated companies because it ensures the safety and efficacy of their products. Quality assurance tools are used to implement standardized processes that result in reproduceable production outcomes of desired levels of quality.

The Role of QA and QC Processes Within Your QMS

A safe, effective product should be the result every time processes are followed. QC involves the testing of products to ensure they meet standards for safety and efficacy. If QC testing uncovers quality issues, it should result in reactive steps to prevent an unsafe product from being shipped and distributed.

All elements involved in product development should be considered during the review. The product must undergo testing to identify the deficiency right after it’s produced. If any deficiency is disclosed, it should be documented and shared with management, so that they can decide whether to approve and release the product or reject it. This chart depicts whether sampled products or processes meet their intended specifications. The Y-axis shows the degree to which the variance of the tested attribute is acceptable.

Why is QC important?

QA helps the business strategize for how it will approach digital quality. Both QC and QA play vital roles in putting a good outcome in customers’ hands and securing revenue for the business. One of the primary differentiators in QA vs QC is where the focus of the work lies. It primarily focuses on processes and procedures for improving quality and preventing defects before they occur. Then, QC focuses on the product to find flaws that remain after the development process.

QC can involve software testing and beta or canary testing, which provide lessons applicable to future projects and products. Without QC, the organization can’t be sure that the product works as intended and suits the customers’ needs. A proper QC process leads to happier customers who have more incentive to be loyal to the company.

QA and QC in the Quality Management System

By the end of this article, you’ll be able to describe precisely how quality control and quality assurance are different, how they’re alike, and how they work together to make products better. Nowadays people are becoming quality sensitive, and that is why they do not want to compromise with the product which is inferior regarding quality. Quality Assurance and Quality Control are the two tools which help to provide quality products to the users. QA and QC processes offer opportunities to improve in areas like defect detection, requirements gathering, and customer experience. This means your organization can potentially improve your processes to become more efficient and effective with each iteration. QA is process-oriented, and it primarily focuses on processes and procedures for improving quality and preventing quality defects before they occur.

However, while these processes feature some overlap, it’s essential to note that they are two separate entities and take place at different times. Elements of the QMS may not be specifically composed of QA or QC activities and responsibilities, but instead involve a combination of the two. Quality control examines the product or service and checks for the result.

Quality assurance vs quality control tools and techniques

Both QA and QC strive to make their workflow as measurable as possible. Having clear deliverables makes communication with other teams easier, allows predicting budget expenses, and measuring the team’s efficiency. This means being engaged in standups and team meetings early on, constantly communicating with stakeholders, reviewing competitors, etc. The direction the Quality Assurance works in is largely based on the feedback from QC specialists.

Quality assurance and quality control are often used interchangeably, but they are two different processes taking place at different times. Each play distinct roles in life https://www.globalcloudteam.com/ sciences companies that are vital for effective quality management. Understanding those roles can help your organization master each to deliver the best products possible.

Cooperation between quality assurance and control teams

While the two terms are often used interchangeably, there are important distinctions to keep in mind regarding their application and function. Additionally, QA and QC complement each other and are deployed simultaneously to ensure that the Quality assurance vs. Quality control work your lab carries out is safe, accurate and replicable. Our field execution platform guides daily tasks, speeds data collection, boosts communication, and gives leaders real-time intelligence to drive the right action, everywhere.

QC takes into account secondary factors as well – such as hardware differences, various OS, browsers, add-ons, API compatibility, etc. Quality Control analyzes the product and provides the QA team with feedback. The goal of the QA team is to find the underlying problem of why the code issues appear.

Develop career skills and credentials to stand out

This cost is regardless of whether you invest in your own QA and QC teams or enlist the help of a testing partner. It is important to invest in the staff and tools needed to ensure quality throughout the organization. Both approaches follow standards the organization defines to secure high quality, but each features a unique system. QC might involve some experimental, fringe, or UX (user experience) testing techniques that require creativity on the tester’s part. However, defect detection and remediation must still be recorded and executed in an organized method.
