As AI automates the 'write code' step, the primary role for human engineers shifts downstream. They will be increasingly responsible for testing and manual verification—tasks historically disliked by developers and previously handled by dedicated QA teams.
QA professionals should evolve beyond verifying that code works as specified. Their strategic value is in validating that features serve the intended business purpose and meet customer needs—a function often missing between business requests and development execution.
Despite the push for more automation, a World Quality Report found that 47% of organizations reported more escaped defects as automation grew. This suggests that automation without strategic human oversight and systems thinking can degrade, not improve, quality.
The most impactful quality metrics are not internal measures like bug counts but those directly linked to customer and business outcomes. QA professionals increase their influence by framing their findings in terms of business impact, financial exposure, and customer risk.
The software industry's move to have developers own testing was a business decision that ignored developers' aversion and lack of aptitude for QA tasks. This organizational failure, not a skills problem, directly led to declining software quality across the industry.
According to a GitLab DevSecOps report, eliminating QA roles resulted in developers taking on 40% more testing tasks. Alarmingly, this led to a 56% increase in downstream incidents, showing increased developer effort fails to compensate for the loss of specialized QA expertise.
AI tools can dramatically accelerate test execution but lack the contextual understanding to interpret results or assess business risk. An effective hybrid model has humans own the 'what' and 'why' (sense-making) while AI handles the 'how fast' (execution).
Businesses often celebrate salary savings from reducing QA headcount. A truthful ROI calculation, however, must subtract the often-hidden downstream costs of increased rework, incident recovery, and the opportunity cost of developers fixing bugs instead of building new features.
The "Shift Left" philosophy was meant to integrate quality expertise earlier in the development process. However, many companies misinterpreted it as simply making developers responsible for QA tasks, rather than embedding QA professionals into design and planning, leading to poor outcomes.
According to McKinsey research, high-performing organizations—those attributing over 5% of EBIT to AI—are nearly three times more likely (65% vs. 23%) to have defined "human in the loop" processes. This indicates that human oversight is critical for realizing significant value from AI.
