We believe the importance of software quality management goes beyond mere expectations. From improving customer satisfaction to protecting your brand reputation, the quality of your software directly impacts your business results.
But how can you ensure that your software meets the highest standards? That’s where software quality assurance (QA) professionals come into play – the anonymous heroes who play a pivotal role in achieving market excellence and ensuring impeccable software performance.
In this article, we shed light on the value that QA professionals bring to the table and delve into their core roles and activities. By exploring this guide, you will get answered the question surrounded by so many misconceptions - why is a quality assurance tester needed on a software development team?
The Value of QA Specialists
QA specialists are indispensable contributors to software projects, bringing immense value to your team and product. Especially in today’s competitive digital environment, where hiring dedicated QA specialists is not just a luxury but a necessity. They bring focused expertise and a keen eye for identifying and mitigating risks throughout the development lifecycle.
Investing in QA expertise is more like a strategic move that elevates your business, ensures customer satisfaction, and sets you apart from the competition. You may ask how? Let’s look at a simple example of what it looks like.
Recent surveys show that software developers spend 20% of their time fixing bugs. The cost to your business becomes clear when you multiply the time spent fixing bugs in your code by the typical hourly rate of software developers. Also, as defects move along the software development workflow, the cost of fixing them increases exponentially. In addition, running buggy software has other negative consequences, such as security holes, degraded user experience, and potential reputational damage.
Moreover, developers’ lack of proper education and qualifications in the QA area results in inefficiency. Since their time is more expensive and less suited for testing tasks, involving them in the software testing process ultimately slows down project delivery.
So, the main goal of QA in software development is to detect problems before they cause serious harm. However, QA's role is not just about detecting bugs but providing ongoing feedback on application quality. Meaning that in the support stage, existing software quality assurance measures are already in place to prevent issues. No new inputs or tests are needed as the focus shifts to supporting and maintaining the project.
These staggering statistics, together with a simple example, underscore the value of QA specialists and the impact they can have on your bottom line.
Deciphering QA Roles: Key Differences between QA, QC, and Tester
Before delving into the clear differences between these QA roles, let's understand the essence of QA vs. QC with a practical example.
For instance, let’s say we have a design for a pen, but the product itself is yet to be created. Our functional quality criterion is straightforward: as an end user, we want the pen to write on paper.
As a QC engineer or tester, your task is to develop a test procedure that verifies the pen's writing functionality. This involves taking a paper, trying to write on it with the pen, and confirming that it leaves marks as expected.
From a QA perspective, you need to analyze the requirements further. Consider who will use the pen and the weather conditions in which it will be used. For example, if it might be used in desert-like environments, we must ensure the ink won't evaporate or become unusable. Additionally, we must assess safety aspects. Should the pen be child-safe? While business-exclusive pens may not be a concern, toxicity becomes a significant risk if it's a typical pen that children might use. Furthermore, we must consider the materials used in the pen's construction. Compliance with safety regulations is crucial, ensuring the materials are non-radioactive and meet applicable standards.
Reviewing this example, you may conclude the main difference between the QA roles lies in their focus. While QC engineers and testers primarily focus on executing test procedures to verify specific functionalities, QA specialists take a broader perspective by analyzing requirements, considering user needs, assessing safety, and ensuring compliance with regulations.

Risks of Testing Without QA Specialists
It’s crucial for companies to recognize the serious risks they can encounter without engaging QA specialists in their software projects. Let’s review the most common of them.
Alt image: Risks of testing without QA specialists
Failure to maintain high development standards
Some companies adopt the ideology that they can deliver great software without the need for dedicated QA specialists. They position themselves as not burdening clients with additional QA costs, which becomes their selling point. While it is true that developers or peers often handle most of the testing, another aspect to consider is maintaining high development standards.
Without dedicated QA, testing becomes primarily automated and relies on developers' project management systems (PMS) and infrastructure DevOps. It becomes a process of checking what is present or missing. This can lead to overlooking essential quality standards and best practices.
Lack of expertise and specialized knowledge
Testing without QA experts means sacrificing their experience and deep understanding of software testing. This can lead to poor test planning, execution and a failure to address important QA aspects. Consequently, there is an increased risk of failure due to the absence of skilled experts in the field.
Inadequate test coverage
Test coverage can suffer due to a lack of dedicated QA staff. QA experts are trained to recognize various scenarios, edge cases, and potential problems that must be thoroughly tested. Some software components remain untested without their participation, which may result in missed bugs and vulnerabilities.
Lower testing quality
Since developers or peers has to take on the role of QA, they may lack the same level of rigor and focus as dedicated QA efforts. QA specialists bring a systematic and structured approach to testing, ensuring comprehensive coverage and accurate bug detection. Without their involvement, it results in lower testing quality.
Increased time and cost of bug fixing
Without dedicated QA staff, the absence of their expertise can lead to bugs and issues going unnoticed until later stages of development or even after the software is released. As a result, fixing bugs can take longer and cost more money because fixing problems found later in the development process is usually more challenging and more expensive.
