Software quality is a crucial indicator of future business success and widespread user demand. You can achieve high-quality indicators through two common practices. They are quality assurance and quality engineering.
Although both approaches have their own specifics, purpose, and goals, they are often confused and used interchangeably. The article below will help you understand what QA and QE are, and learn what their main differences and functions include.
Achieving High Software Quality
Companies can use different approaches to thoroughly test software and ensure that it meets documentation requirements and user expectations. Some of them resort to QE while others prefer QA. In addition, some teams can handle testing in-house, while others can involve third-party engineers. If you have to test a product and do not have enough resources of your own, engaging a vendor like testfort.com can help.
However, in any case, you should understand the difference between QE and QA and know how to achieve better results through their cooperation.
Purpose and Principle of Quality Engineering
QE is an approach based on taking into account quality considerations from the beginning and throughout the entire software development cycle. Its goal is to implement tools, methods, methodologies, and processes that will allow you to track the quality of the product continuously and, as a result, deliver a high-quality program or application.
Implementing various methods of achieving quality is the task of quality engineers. They work closely with developers at each stage of building a product and ensure that their tools minimize the risk of errors after the development phase is completed. In addition, they:
- Define key quality standards.
- Implement variational methods and control tools.
- Cooperate with the team.
- Conduct code reviews.
- Work on the development of test automation systems.
- Analyze key quality indicators and work on their improvement.
Quality engineering is an early implementation approach that is designed not to detect defects but to prevent their occurrence. To adopt quality engineering testing means to take care of developing better software in the initial stages.
Primary Differences and Features of QA
Unlike QE, QA is an approach that focuses on testing software using various methodologies and techniques. Its goal is to find defects and bugs in the product and report them to the development team to ultimately create a program or application that fully meets the customer’s requirements and user needs.
Quality assurance engineers do not implement tools to minimize risks. Instead, they take care of thorough testing of products before their release. They:
- Develop test cases and execute them.
- Look for possible defects by analyzing all components of the software.
- Report bugs to the developer and conduct retesting.
- Perform manual and automated testing for different devices and operating systems.
- Provide recommendations on how to improve existing software.
Although QA has a different purpose, its role in the development and release of the product is not unimportant. It is designed to ensure that there are no risks of breakage and that the program functions optimally.
From QE to QA Evolution
Previously, software testing was exclusively the final stage of its development. Teams rarely cooperated and implemented product verification at the early stages.
However, thanks to the emergence of agile methodologies, the beginning of software testing has become possible at all stages of product development. The quality assurance to quality engineering transformation was the start of the transition to new approaches to testing programs and applications.
The evolution of practices has improved the testing experience and brought many benefits. However, they still work best in a bunch.
Why Collaboration Between QE and QA is Necessary
QA implements processes to achieve high-quality performance, while QA verifies the effectiveness of the implemented processes through testing. That is why both practices are crucial to producing a profitable product that will be in demand.
To achieve better results in software development and testing, QE and QA can:
- Communicate and exchange information on the best methods and tools to reduce risk and improve product quality.
- Plan and prioritize tests.
- Develop test plans and cases that will have better coverage and help to test the product before release.
- Share modern practices and features to improve the testing experience and implement the most suitable tools.
Involving both practices is always the best option, however, the final decision may vary depending on the circumstances.
Final Thoughts
QA is a proactive approach that focuses on preventing defects. It requires strong technical skills and involves the development of quality processes. QA is a reactive approach that focuses on defect detection. It requires strong analytical skills and involves the development and execution of test cases to test the software. Both of them are essential in achieving quality metrics to deliver a reliable and trouble-free product.
