Why hire a quality assurance engineer when you can hire more highly experienced developers? Many think that the task of a QA engineer is solely to track bugs in the development process of software. Even though humans are more prone to making mistakes, that is not the only reason every developing team must have a QA engineer in the squad. So, what exactly does a tester do, and why is it such a significant role?

1. They save money
Fixing a bug detected in the preliminary stages of the development process costs much less than fixing it when it’s too late. That is why every company should hire QA engineers at the very beginning stages of a project.

2. They also provide security.
Security is one of the key things that any user or client looks for when using software. If the product goes under testing at all stages, the chances are higher that it will be a reliable product.

3. They ensure the quality of the product.
When a team is working on a project, numerous requirements are clear only to somebody or are spread in documents and chats. The tester makes sure that nothing slips into production and that every unit or system developed meets the overall goal of the product based on the client’s requirements.

The work process of a QA engineer is crucial for the software to fully function, provide a good user experience, and have full compatibility with various operating systems and devices.

4. They ensure customer satisfaction.
The overall success of any project stands on its quality and the customer experience it supplies. That is the number one requirement of every client. But if the developed software has glitches and doesn’t work, the client will lose faith and won’t trust your team anymore. Hiring a professional QA engineer is a prerequisite for every professional company to succeed and deliver a great final product.

5. Improves the process development
When a developer works on a specific feature, all his efforts are concentrated on making it work perfectly. But somehow, the developer might slip the fact that these changes might impact previously developed features. The tester must work in parallel with the developing tea to track changes and fix them in the preliminary stages.

6. They determine the software performance.
QA engineers are the ones that evaluate the product inside-out. They check everything from integration to UI, data, and security and ensure nothing has slipped through the development process. That makes their role particularly important to determine if the product to be released will work well in any condition and meet all the requirements.
