What is Software Quality Engineering? Definition and Benefits

Software quality engineering (SQE) is the process of implementing quality checks throughout the entire development cycle. SQE plays a key role in ensuring fast-paced agile and DevOps teams produce high-quality software.

Software quality engineering practices

Software quality engineers use several practices to ensure a high-quality product. Some of these practices include:

Peer review

Peer review is when the software developers share their code with one another. Having programmers review each others code provides two major benefits. First, it makes it more likely that they will spot any errors by giving each piece of code additional reviewing. Second, it allows the programmers to learn from one another. Programmers can share advice or suggestions to help improve the softwares code, which ultimately leads to a better product.

Code analysis

Software quality engineers integrate analysis tools directly into a programmers coding environment. Through these tools, the programmer gains real-time feedback about their work, ensuring that it conforms to pre-defined quality standards. This real-time code analysis saves the development team time by eliminating problems before they become ingrained within the program.


There are several testing practices that software quality engineers use. One example is functional testing, which tests the user interface of an application to ensure it conforms to the predefined protocols. Along with testing out the core functions of the program, functional testing also analyzes the performance of features such as menus and the installation process.

Another testing procedure software quality engineers use is user performance testing. This aims to test the speed of a product under different circumstances. By doing this, engineers can ensure the program meets customer expectations.

What is software quality engineering?

Software quality engineering is the practice of integrating quality checks throughout the development cycle of software tools and applications. Its purpose is to ensure the software development team is efficiently testing for quality throughout the product development cycle. To do this, software quality engineers must closely study existing development processes so that it can integrate the quality checks, rather than add them on top. Software quality engineers are responsible for the design, development and maintenance of the policies and procedures used for improving the efficiency of quality assurance.

Software quality engineering vs software quality analysis

Software quality engineers and software quality analysts both aim to ensure a high-quality final product but have distinctive roles. Software quality analysts work to develop and implement quality standards during the products design stage. They typically create the environments for testing and may carry out the quality tests themselves.

Software quality engineers, however, focus on improving the efficiency of quality assurance. They begin their work after the software quality analysts complete their work and submit the quality assurance requirements. Software engineers may perform tasks such as automating tests, identifying repeated tests and identifying issues that arise from testing procedures.

Why is software quality engineering important?

Software development teams use software quality engineers because they can provide the following benefits:

Better final product

By checking for quality throughout the development process, software quality engineering ensures a better final product. It handles more problems and inefficiencies during the development process so that there are fewer when it comes time to deliver the product to the customer. Software quality engineering also promotes collaboration among developers, who can then share ideas for improvement. This encourages an environment where the developers can find the best ideas and implement them.

Faster delivery speed

Through practices such as automation and the use of artificial intelligence, software quality engineering significantly reduces the amount of time spent on testing. Because of this, developers can finish the software faster and deliver it to the customer sooner. In software development, delivering a high-quality product to the customer in a timely fashion is one of the most important attributes of any development company. Therefore, the faster the company can deliver a product, without sacrificing quality, the better.

More adaptable

When developing software, you may face unexpected challenges. For example, a client may request major changes to the product in the middle of development. Software quality engineers help their businesses implement what is known as agile development practices. These allow development teams to quickly and efficiently make changes during the process, ultimately saving time and resources.

Typical education for a software quality engineer

Consider these common education steps to become a quality engineer:

Earn a bachelors degree

Software quality engineers typically need at least a bachelors degree in a related field, such as engineering, software design or computer science. These degrees provide foundational knowledge of software design principles, which software quality engineers need to know if they are going to implement their practices seamlessly into the process.

Consider a masters

Some positions may require or prefer a masters degree as well, also in a related field. A masters degree provides even more in-depth instruction on software development, allowing software quality engineers to implement even better procedures.

Gain practical experience

While in school, consider taking an internship related to software development. Most employers like to see practical experience on a resume and an internship is a good way to start out. Through an internship, you can gain hands-on experience with the software development process and learn more about quality assurance implementation.

Consider certifications

Finally, there are professional certifications available for software quality engineers. These certifications provide proof of your capabilities related to quality assurance and software development. Many professional certifications require a few years of working experience before applying, making this something to consider after becoming a software quality engineer.

Software quality engineer job description

Primary duties: Software quality engineers typically work for software development, computer design or electronics manufacturing companies. These companies exist in a range of industries, allowing software quality engineers to work on a variety of projects. For example, a software quality engineer could work for a software development company that provides word processing software, one that develops healthcare apps or one that produces video games.

Regardless of the position, most software quality engineers typically work in an office or lab setting in front of a computer. Depending on deadlines, they may need to work overtime on nights or weekends to complete a project on time, but typically work 40 hours per week.


What is the role of software quality engineer?

What Software Quality Assurance Engineers and Testers Do. Design test plans, scenarios, scripts, or procedures. Document software defects, using a bug tracking system, and report defects to software developers. Identify, analyze, and document problems with program function, output, online screen, or content.

What is difference between QE and QA?

The focus of quality engineering

Ultimately, QE provides focus on testable requirements that are implemented through the creation phases and beyond. On the other hand, quality assurance has a more defined focus. Simply, QA looks to improve quality through testing.

What does Quality Engineering mean?

Quality engineering is the discipline of engineering concerned with the principles and practice of product and service quality assurance and control. In software development, it is the management, development, operation and maintenance of IT systems and enterprise architectures with a high quality standard.

What is software quality explain with example?

Quality software refers to a software which is reasonably bug or defect free, is delivered in time and within the specified budget, meets the requirements and/or expectations, and is maintainable. In the software engineering context, software quality reflects both functional quality as well as structural quality.
