An in-house QA team is one of the highest-leverage investments a software organisation can make. Bugs caught before release take a fraction of the time to fix compared to bugs discovered in production, and the reputational cost of shipping broken software is harder to quantify but just as real. A dedicated quality assurance function pays for itself many times over by keeping releases clean and customers confident.
What Is QA Testing in Software Development?
Quality Assurance (QA) testing is the process of systematically identifying bugs, usability issues, and performance problems in software before it is released to users. Good QA covers multiple dimensions:
- Functional testing: does the software do what it is supposed to do?
- Regression testing: does new code break existing features?
- Performance testing: does the software hold up under realistic load?
- Security testing: are there vulnerabilities that could be exploited?
- User acceptance testing: does the software meet the end user's actual needs?
Together, these testing types form a safety net that catches problems while they are still cheap and easy to fix.
Why Does a Dedicated QA Team Outperform Developer Self-Testing?
Do Developers Testing Their Own Code Miss Things?
Yes, consistently and predictably. Developers have blind spots around their own implementations. They know exactly how they intended the software to work, which makes it genuinely difficult to approach it as a new user would. They are also under time pressure to ship, which means edge cases get deprioritised even when there is good intent to catch them.
Dedicated QA testers bring a different perspective. They approach software the way a user does, exploring paths the developer didn't anticipate, testing edge cases that weren't in the original spec, and evaluating whether the experience actually makes sense to someone encountering it fresh. The result is a significantly higher bug catch rate before release.
How Much Does It Cost to Fix a Bug in Production Versus QA?
The cost difference is substantial. A bug identified before release might take an hour to fix. The same bug discovered in production could cost days of emergency developer time, user trust damage, and potential data integrity issues. The investment in QA pays back many times over, not just in reduced fix costs but in avoided incidents that are difficult to put a number on.
What Does In-House QA Deliver That Outsourced Testing Doesn't?
When your QA team sits alongside your development team, the feedback loop is tight. Testers can ask developers clarifying questions immediately. Developers understand how testers work and write code with testability in mind. Issue resolution is faster because there is no handoff delay across organisations or time zones.
An embedded QA team also builds domain knowledge over time. They understand the product's history, know which areas are fragile, and can focus testing effort where risk is highest. That accumulated knowledge does not exist in an outsourced testing arrangement.
How Putti Approaches QA
Putti has a dedicated QA team integrated directly with its development team. Every product Putti builds goes through both manual testing for complex user flows and automated testing pipelines for regression coverage. The QA and development teams work in parallel, not in sequence, which means issues surface early when they are easiest to address.
Putti also offers standalone QA services for software built by other teams. If you have an existing product that needs a rigorous quality pass, or you want an independent review before a major release, the team can step in without needing to own the full development engagement.
If your software releases are producing more bugs than you'd like, or if your development team is spending too much time firefighting production issues, a dedicated QA function is likely the missing piece. Talk to us about what a QA engagement could look like for your team.
