How to Quality Control a Product?


7 min read

Imagine walking into a local shop and seeing every item of clothing in the same color and size. That is practically a characterization of software that was never tested. It either fits your demands (by chance) or it’s absolutely worthless. The goal of creating a software product is to meet a wide variety of demands, and product quality assurance testing is the most effective way to do it.

QA software testing and QC appear to be identical things to someone who is unfamiliar with software testing and development. In reality, these two words are frequently mistaken and used indiscriminately. Nevertheless, there are some distinctions between the concepts, and we want to assist you in determining them. In this post, you will get familiar with software product quality control checklist, as well as understand the contrasts between the two and see examples of each.

What is Product Quality Control?

Quality control is a collection of operations used to ensure the accuracy of software products. It is a QA-governed procedure whose major purpose is to find problems in the actual product generated, like defects, malfunctions, or deviations from requirements.

Among the advantages of product quality control testing are:

  • Increasing quality mindfulness.
  • Lowering manufacturing costs.
  • Reducing complaints after the service has been distributed.

Finally, quality control has two critical goals:

  1. To guarantee that goods are as inclusive as possible.
  2. To eliminate mistakes and errors within them.

What is Product Quality Assurance?

Product quality assurance process is a critical component of software development. It aids in the monitoring of the software development process, ensuring that it is progressing along the appropriate path. However, the biggest advantage of QA is in its primary role—the detection and avoidance of product faults.

The benefits of software quality assurance are meaningful:

  • Early detection and avoidance of problems during the SDLC.
  • Interaction between the testing, development, and management functions should be improved.
  • Improved product quality leads to a competitive advantage.

So, does strong quality assurance eliminate the necessity for quality control in your business entirely? Certainly not. Software development is inherently risky and prone to errors. There is no certainty that additional system upgrades will not introduce inconsistencies in what has already been established. And here is where quality control in product development comes in.

Different Types of Testing to Perform

A good strategy for the testing process must consider the following:

  1. Risks: evaluate the dangers when testing. Is it possible that testing may cause software to malfunction? For instance, if a program is already popular in the online market, testing for additional features or upgrades may cause the app to crash or scramble certain functions. In this situation, testers should consider regression-averse tactics.
  2. Priorities: is the testing approach meeting all of the stakeholders’ expectations and objectives? Tests should not only determine if all software elements work properly, fulfill business objectives, and really benefit customers.
  3. Guidelines: does the software being tested comply with all professional regulations? Typically, different restrictions apply to the same app or website in various geographical locations. The testing team must be familiar with local rules to ensure that the program does not unwittingly violate the law.

Automated Testing

Since all tests are done without human intervention, the QC team may save a substantial amount of time and effort by automating the process. A computer executes a test script produced during the basics of the test planning phase to conduct automated tests.

Automation is typically used for repeated activities as well as other types of testing that are tough to accomplish manually.

Manual Testing

Manual testing, in contrast, is done by a human who goes through the application to run the test scripts. This is costly and time-consuming as it needs personnel to carefully set up an environment and run the tests.

Automation cannot completely replace manual testing. It comes with its own set of benefits, which means that not all testing operations can be automated.

Exploratory testing is a remarkable illustration of this, as the entire process is frequently unexpected, requiring a high level of research and intelligence as well as some prior understanding of the app, and cannot be completed by a machine.

As a consequence, when both strategies are utilized, the most efficient and complete result is obtained.


Following the testing process, the QC team provides a test report that includes a description of all completed testing operations as well as final test findings. It is not just necessary for the testers to provide an overview of how successfully their task was completed.

The test software applications report provides stakeholders with an understanding of the tested product performance, allowing them to make an informed choice about whether or not to launch the program.

Difference Between Product Assurance and Quality Assurance

Although the phrases “quality control” and “quality assurance” are sometimes used reciprocally, they each refer to distinct duties and activities. Whereas quality assurance in software testing is concerned with maintaining quality throughout the software development process, quality control is concerned with discovering errors and flaws in finished software products. As a result, QA processes are more focused on prevention than quality control, which is more focused on diagnosis.

The nature of the two is also distinct. Quality assurance is more organizational in scope, concentrating on all software development operations inside a business. Software quality control is a collection of operations that focus on controlling the quality of a particular software product. However, quality control and quality assurance are almost always mirrored throughout an organization’s full range of software products.

Furthermore, whereas quality assurance is employed throughout the life cycle of software development, quality control is often limited to the evaluation and testing phases. Yet, testing is a regular activity that is essential to both QA and QC.

Methods and Approaches

If a software product is extensive and designed to run on several platforms and devices, it should be thoroughly tested. Many comprehensive QA methodology and tools are required for this, which thoroughly examine the products and services to determine whether or not they match their set standards. QC and QA testing methodologies include unit testing, integrated testing of software, and testing of the full software system, with examples we provide below.

  • Unit testing: involves developers focusing on minute functional units, isolating each unit, and testing their functioning.
  • Integration Testing: developers now design a method in which distinct software modules relate to one another, their cross-operational and communication are developed, and the program is tested.
  • Functional Testing: testing approach of output to input functionality of the program is used to examine every single function of the software.
  • Regression Testing: developers use this to ensure that problem fixes are only applied where they are needed. Regression testing is used to ensure that problem fixes are kept to a minimum and do not interfere with other program functions.
  • System Testing: after the software has been incorporated altogether, it is tested again to ensure that it is operating properly at all levels.
  • Performance Testing: after the issues have been solved, the program is evaluated for speed and efficiency.
  • Acceptance Testing: this is the ultimate stage of software testing in which the software product is examined by users to determine how they enjoy the program.

Different types of quality assurance and modern technological trends are continually altering and improving our lives through digitalization. According to the latest trend, automation and digitalization have enhanced everyone’s lives.

A little mistake can have an immediate impact on the size and income of any firm. As a result, it is critical to always solve issues. As a result, the demand for software quality testing in the United States is rapidly increasing.

Importance of QC and QA

Eventually, investing in QC and QA in software development procedures may safeguard a company’s brand, avoid unreliable products, and build consumer trust. These methods are defined by strict criteria and evaluation, as well as industry guidelines and best practices.

Furthermore, quality control is required since it assures that a corporation will employ evidence-based data and research, rather than personal observations, to verify that items live up to its standards. One critical component of quality control is that it is a continual procedure that evaluates the product to verify that it is satisfying both production standards and customer needs.

No customer would like to use a product that might disturb them or not meet their expectations. If quality control techniques are neglected, a company’s reputation, dependability, and efficiency are all jeopardized. Testing a service may help with both sales and marketing by increasing customer trust.


There are numerous examples of software disasters wreaking havoc throughout history. Still, one of the most controversial challenges in software development is quality control for products. Many software companies doubt it’s worth as a separate procedure, putting their businesses and goods at risk in order to save some money.

It is critical for any custom software development services firm in the United States to select appropriate software testing approaches, processes, tactics, and tools that are best suited to the product’s main functionality. Consider all testing process steps to be a dynamic activity that must be accomplished within each timetable in order to obtain a more flexible and successful IT software product.
