Quality Assurance vs Quality Control: Main Differences

Your organization can achieve Quality Assurance (QA) by putting into practice a Quality Management System (QMS). This system will help with the prevention of quality issues in all departments of the firm. Another way of looking at Quality Assurance (QA) and Quality Control (QC) would be to recognize what type of tools those are. For example, you can perceive QA as a managerial tool for preventing various quality issues. At the same time, QC could be an operational tool, for identifying and correcting the defects before the product enters the market.

Principal distinctions between QA & QC

The benchmarking approach is based on the comparison of your work with the best practices in other departments, enterprises, or the whole industry. With benchmarking, you can identify the weak spots of your business and determine the methods for their elimination. QA is a series of activities that are determined before production begins. These activities start together with a project and take place during the whole cycle. QA ensures that all of the agreed methods, approaches and techniques are implemented without deviations in order to prevent mistakes and, as a result, satisfy the customer’s needs. Quality Assurance and Quality Control are related to each other, but they are originated based on different needs.

Introduction to Quality Management and Its Core Advantages

QA is process-oriented, and it primarily focuses on processes and procedures for improving quality and preventing quality defects before they occur. 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. If you establish QC standards that result from the QA activities, you need to remember to keep the top quality of the software, guaranteeing that it satisfies your clients. The final digital product performance directly affects its profitability.

In contrast to QA that concerns the process of production, QC deals with the output. The main function of this practice is to verify deliverables and detect mistakes if any, so that a defective solution doesn’t reach a customer. In general, QA is a proactive method used to mitigate risks before a project is finished and monitor the software engineering processes in order to create a solution according to the agreed standards. Thus, the main goal of QA is to organize flawless development and to protect the final product from possible defects. The main point of Quality Assurance (QA) is to prevent any defects before they occur. Therefore, Quality Assurance (QA) is a proactive activity by its nature.

The Benefits of Quality Control

QC, meanwhile, involves measuring activities to verify the finished product before distribution. Quality control (QC) is not separate from quality assurance but rather a part of it. Quality assurance vs. Quality control Get in touch to receive a consultation on your product testing strategy. Although QA and QC are independent units, fully splitting these two processes may lead to three key risks.

Quality Assurance (QA) and Quality Control (QC) are both parts of the software quality management process. Thus, they serve to ensure the end product corresponds to the defined standards and needs. Life sciences organizations should “close the loop” on quality management processes by using QC to inform QA. When non-conformances are discovered, it’s important to launch an investigation to determine where the breakdown occurred in QA processes and create stronger standards. We’ll review quality assurance and quality control meanings, definitions, acronyms and processes and then compare quality assurance vs quality control. If you’re ready to pursue a career in quality assurance and quality control, you can start your journey to your quality management job.

Examples of Quality Control

Fast and precise order delivery to clients is a more crucial criterion because it directly impacts their pleasure and the quality of their experience in all types of restaurant management. Using methods to reduce nonconformity, the upgraded process with process validation has significantly reduced the percentage of nonconforming parts. Based on their suggestions, you might declare to satisfy your customers’ needs.

Principal distinctions between QA & QC

The process(es) which are managed with QA pertain to Total quality management. The defect management approach is mostly used to develop good software. All features that don’t correspond to them are considered defects. They are grouped into categories according to the severity and must be avoided (or eliminated) while in development. On the other hand, the main goal of Quality Control (QC) is to identify any possible issues, prevent them, if needed, and verify the quality of the product or output.

Failure testing

Since QA and QC are tightly connected terms, let’s take a closer look at how these two concepts differ in objectives, focus, breadth, activities, and completion times. When test findings are irregular, CAPA should take place to investigate the problem’s fundamental cause and improve procedures to ensure it doesn’t happen again. Quality control issues resolve potential concerns, even if cybersecurity is more of an IT team’s responsibility.

  • You should also understand the legal standards in the various fields, especially the one in which you want to work.
  • Inspection involves physically examining the deliverable for any defects to see if it matches the requirements.
  • The primary goal of a quality control process is to make sure there are no defects in a product or service and that quality requirements are being fulfilled.
  • The quality of products is dependent upon that of the participating constituents,[26] some of which are sustainable and effectively controlled while others are not.
  • The decision to use QC or QA depends on the specific needs and objectives of your organization and the stage of your product lifecycle or service delivery.

Opportunities open up in various sectors when you pursue a career in quality management. You can work in software development, customer service, hospitality, product testing, marketing, and many other industries. Your quality management skills will translate if you decide to switch fields.

Quality control, quality assurance & quality systems

A Trainee who lives up to the expectations advances to the next level upon the internship becomes the “Junior”. So, the Junior specialist understands the QA processes well and can work independently or with minimal mentor’s support. These two ideas are both parts of quality management and share the same goal. It’s that part of quality management that is about ensuring you will meet requirements in the future.

Principal distinctions between QA & QC

The Capability Maturity Model Integration (CMMI) model is widely used to implement Process and Product Quality Assurance (PPQA) in an organization. The CMMI maturity levels can be divided into 5 steps, which a company can achieve by performing specific activities within the organization. Again, this would depend upon how mature the organization’s Quality Assurance or Project Management practices are, and how exactly the organization wants to enhance them in the days to come. Here is how the R-Series can contribute to lowering a manufacturer’s total quality costs. They are known as Statistical Process Control (SPC) when applied to operations (process inputs & operational parameters) and become a quality assurance component.

Cooperation between quality assurance and control teams

So, does good quality assurance completely remove the need for quality control in your project? There are no guarantees that new system updates won’t add discrepancies to what has already been developed. Software Quality Assurance (SQA, or QA) is a part of quality management focused on providing confidence that quality requirements will be fulfilled. Statistical Quality Control (SQC) is the term used to describe the application of statistical tools and methodologies to finished goods (process outputs) and is a subset of quality control (QC).
