A Teammate, Not a Roadblock

Martina Polakova,

When you hear the term “QA Engineer,” many people imagine someone whose job is to find faults in other people’s work. As if their main role is to say, “This doesn’t work” and slow everything down.

But QA, short for Quality Assurance, is not a controller or a critic. They are part of the development team. Their job is to help deliver a product that works the way it should. That means reliably, consistently, and without unnecessary surprises for the user.

So what does QA actually do?

In simple terms, QA tests what developers build. But it’s much more than just clicking around and spotting bugs.

QA looks at the product from the user’s perspective while also thinking about how the system works as a whole. They check whether different parts of the application function correctly, whether they interact properly, and whether the product behaves as expected in real situations. For example, what happens when the internet disconnects, the user enters incorrect data, or interacts with the system in an unexpected order?

They use a mix of manual testing and automated scripts that regularly check the health of the product after new changes are made.

It’s not about finding mistakes, but about preventing problems

Good QA is not just about reporting bugs. It’s about asking the right questions. Is this intuitive for the average user? What happens if someone uses this in the wrong way? Did we accidentally break something that used to work?

QA focuses on reducing risk. With their help, the team can release new features with more confidence, knowing they’ve been tested in realistic scenarios.

More features don’t always mean a better product

Many companies focus on speed. They want more features, faster releases, constant updates. QA reminds the team of something equally important: quality.

A product with ten unstable features is far less valuable than one with three that work smoothly.

Users trust products that are stable and dependable. Once that trust is lost, it can be very hard to earn it back.

There’s no such thing as a bug-free product

Even the best teams with the most experienced QA professionals can’t guarantee perfection. Software is complex, and people use it in unexpected ways.

That doesn’t mean QA has failed. Their role is not to eliminate every possible bug but to catch serious issues before users run into them. The goal is to build confidence in the product’s reliability.

A bug isn’t failure. It’s a chance to improve

If a bug shows up after release, it doesn’t mean someone failed. It means there’s something new to learn. It’s part of a process that helps the team get better over time.

When a team responds quickly, understands what went wrong, and applies a fix, the product becomes stronger.
