Most of the businesses are now thriving to match the level of quality and accuracy within apps and become the best of breed businesses. Here the two major factors are quality assurance and quality control. But often for the sake of maintaining quality assurance, they tend to forget how quality control can be done? Yes, both these are two different things. If you ask a QA engineer to state the difference, you would get the actual picture. They just don’t identify errors and rectify them, but they have a huge role in QA testing in making the developed application faster and high-performing.
In this blog post, we are going to slow down on each of these aspects- quality control and quality assurance and how are both of these different from each other.

1. What is Quality in software?
The software quality of any product is dependent on many factors. It depends on how your businesses are fulfilling quality requirements. This is a process-oriented method that involves quality parameters. One of them is Process design, which includes establishing standard operating procedures, as a part of QA (SOPs). Quality in software means you must follow every time protocol. The end result should be a safe, effective product.
The testing of items to verify that they satisfy safety and preconditions of requirements or not. If quality concerns are discovered during QC testing, immediate action should be taken to prevent a hazardous product from being delivered and distributed.
There are QA analysts performing various quality audits with quality management systems to ensure we meet all quality standards. The testing team initiates software testing in response to all QC concerns. Thus, we can easily identify defects and provide an appropriate method of software testing. Nonconforming test findings should trigger a corrective and preventative action (CAPA) inquiry to discover the root cause of quality issues and change systems to avoid recurrence.
2. Exploring What is Software Quality Control?
QC is a software engineering process that ensures the quality of products or services meets the quality system. Quality control differs from quality assurance in that it analyzes the quality of the final products rather than the process. QC is made of activities that are focused on the end result and are product-oriented. The purpose of quality control is to provide confidence to companies wanting to develop an app that fits product quality as well as customer requirements.
Whenever a QC discovers a fault with the final product, it should preferably be rectified before the end-customer receives it. To put it another way, quality control (QC) is the process of ensuring that a product or service fulfills both conventional quality criteria and client needs. There are certain quality control activities that you can take in the software development phase itself. These activities can be pre-defining processes, timely Quality Audit, statistical process control, and similar quality management-focused approaches.
3. What is Software Quality Assurance?
To understand it briefly, let’s divide the two words- Quality and Assurance. Assurance in terms of Organization means enterprise management that provides assurance that the developed product will perform at its best. Gain trust in advance that the outcome will be favorable. The assurance means promising that the product will meet the customer’s expectations and perform flawlessly.
Now when it comes to quality and assurance coming together, it means assuring you develop a high-performing application with innovative quality management tactics. The quality assurance function used by organizations ensures that their methods for attaining the intended outcomes meet particular quality criteria. Since QA strives to produce consistent results through a set of defined procedures. In a nutshell, quality assurance (QA) encompasses all efforts centered on creating standards and processes for verifying that software fulfills specific requirements.
4. Quality Assurance vs. Quality Control: The Major Differences
|Quality Assurance||Quality Control|
|Quality assurance is a proactive process where we take measures in advance.||Quality Control is a Reactive process that is performed when flaws are identified.|
|In quality assurance, you examine the plan to see if it was effective in avoiding any potential flaws.||In quality control, you look for flaws in the product and try to fix them while it’s being made.|
|Quality assurance is concerned with defect prevention||While quality control is concerned with detecting the flaws.|
|This process ensures that the product deliverable is of greater quality||QC activities involve validating that we have maintained the quality of the product.|
|When you perform the Quality audit, it is a part of Quality assurance.||In the case of QC, the testing procedures and analysis is the main process|
|So, if we say quality assurance is a plan||Quality control is to check if the implementation of the plan is accurate or not.|
5. Real Life Example of Quality Management
Suppose if you bought a headphone, and when you opened it, you found that the product promises noise cancellation as a feature but as a product, it did not meet this QA standard. The operational techniques involved were unable to identify the defect and prevent it. This involves executing incorrect QA activities. In such cases, what went wrong was very transparent. The QA process should have been taken meticulously into account so that quality management becomes easier and simple.
Even when a software development company pioneering in developing cutting-edge software faces challenges when they start with completely new technology. That’s where outsourcing QA comes into the picture. When your business wants to maintain high-quality products then it demands proper planning and technology training in place. Apart from the basics, what’s more important is to have a Quality control plan in place.
With the advancement of the project, the QA team should keep an eye on potential risks and make sure the appropriate individuals are involved at the right time to resolve. By analyzing the system, and using various testing statistical techniques, you can resolve the errors. Unit Testing, functional testing, user acceptance testing are generally required as part of the QC process. Any problems discovered during testing must be reported and handled correctly and in real-time.
6. Advantages of Quality Assurance and Quality Control
As a part of quality management, you must ensure and get all the benefits of maintaining quality assurance QA within your company. Though, you also have an option of outsourcing QA through third-party companies. The following are some of the advantages of maintaining QA within your business. An assurance quality control system helps you to continually meet your product or services in a more streamlined and effective manner.
- You can have improved process controls,
- Regulatory audits go more smoothly.
- An internal system of checks and balances to ensure product quality.
- Collaborative and improved product-oriented culture.
- Employee and management training should be improved.
- Employee involvement can be improved.
7. Final Words
With this, we have come to the end of comparing the most debated topic- the difference between Quality assurance vs Quality control. In this blog, we have seen how essential both these activities are for the software development life cycle. When we have both these methodologies in place we can ensure that the product is developed as per customer requirements and with full-fledged QA testing and analysis. The QA aims to get results from continually met QA processes and standards. It prevents all the defects and provides assurances that whatever is developed is of high-quality, high-performance, and secure for customers.
