Discover why it might be time to rethink assigning testing tasks to your engineers. Dive into the benefits of a dedicated QA team, and how it can elevate your product's quality and efficiency.
What if we told you it might be time to break with tradition and stop assigning testing tasks to your engineers? In this article, we're getting into the 'why' behind this choice and exploring how it can perk up your QA efforts.

Why should my engineers not serve as QA?

The main reason your engineers shouldn’t double up as your QA team is the potential conflict of focus. While engineers are great at creating products, QA tasks need a different mindset – one that focuses on finding  potential issues and ensuring product quality. Giving both responsibilities to engineers can divide their attention and affect the quality of both tasks.

Moreover, having a dedicated QA team brings a fresh perspective and a more comprehensive approach to testing. It brings in a diversity of skills, ideas, and insights that can uncover vulnerabilities engineers might miss. This collaborative dynamic often results in more well-rounded testing and improved product quality.

Let’s explore further through four specific reasons: 

1. Expertise

Engineers, while highly skilled in coding and development, may not have the same expertise in testing methodologies as dedicated QA professionals. While they handle basic functional testing, they might lack the in-depth knowledge and experience required for comprehensive testing. 

A QA team, on the other hand, is well-versed in various testing techniques, such as regression testing, load testing, and usability testing. They bring a broader range of testing skills to the table. They are trained to uncover subtle issues that engineers might overlook. This specialized knowledge is especially useful in industries with strict quality standards, like healthcare or finance, where rigorous testing is essential for compliance and user safety.

2. Objectivity

Engineers working closely with a project often develop a deep familiarity with the codebase and may inadvertently approach testing with certain biases or assumptions about how the software should function. On the other hand, a dedicated QA tester approaches the software with a fresh perspective.

Consider a mobile app in which an engineer has been instrumental in designing and developing a particular feature. The clarity they have in how the feature is meant to be used might lead them to believe that users will intuitively know how to use it. 

However, a QA tester with no prior involvement in the feature may identify issues related to user interface inconsistencies or unexpected behavior. They might find that certain user interactions are confusing or that the feature behaves differently on different devices. QA testers provide valuable insights that engineers could easily miss because of blind spots. This objectivity goes a long way in delivering a seamless user experience.

3. Time Allocation

In many software development projects, time is a precious resource. Engineers are primarily responsible for designing, coding, and maintaining software. When they are also burdened with extensive testing responsibilities, it can lead to time pressures that impact the quality of testing. 

Picture a scenario where an engineer is tasked with both coding and testing a complex feature within a tight go-to-market deadline. The deadline pressure may lead to hurried testing, leaving room for critical issues to slip through. 

A dedicated QA team that prioritizes testing, allocates ample time for it, and conducts systematic testing can help ensure high software quality. They focus on extensive test case coverage, identifying edge cases, and simulating real-world scenarios. This approach increases software robustness and reliability, ultimately reducing the risk of post-release issues and customer dissatisfaction.

4. Cost-Effectiveness

Having engineers handle both coding and testing may seem cost-effective initially, but can lead to inefficiencies and hidden expenses in the long run. Engineers are typically hired and compensated for their expertise in software development. Testing is an extension of their skillset, rather than a competency they are already trained in. Allocating their time to testing tasks can be less cost-efficient. For instance, if a senior software engineer spends a significant portion of their workday on testing, it could be considered an inefficient use of their high-value skills and a potential waste of company resources.

Dedicated QA professionals are specifically trained and hired for testing roles. They are often more cost-effective in terms of hourly rates compared to software engineers. If QA teams are focused on testing tasks, engineers can do what they do best – designing and coding software. They can dedicate more time to creating innovative solutions and addressing complex technical challenges. This allocation of resources not only optimizes costs but improves overall productivity. 

Further, QA teams are experienced in specialized testing tools and methodologies, which enhances efficiency and reduces the long-term cost of identifying and fixing defects in the software. Ultimately, the cost-effectiveness of using dedicated QA teams contributes to the overall economic viability and success of a software development project.

Tips to Develop Your Own QA Team

Building an effective QA team is essential for ensuring high-quality products and efficient development processes. Here are some key tips to keep in mind:
