Earlier in my career, I used to believe that maintaining a healthy ratio between Engineers and QA Engineers was one of the keys to ensuring product quality.
In many teams, QA becomes the final gatekeeper.
Engineers ship to staging, mark the ticket “Ready for QA”, and move on.
With the right Engineer-to-QA ratio, this model allows teams to move fast while still keeping quality under control.
Over time, I started to see the downside of this model.
Some Engineers subconsciously rely on QA to validate quality.
Trivial issues reach staging.
Ownership becomes blurred.
And scaling requires hiring more QA just to keep up with delivery speed.
When I began leading QA myself, I decided to shift the mindset.
From bug detection → to bug prevention.
From late testing → to shift-left testing.
This creates two powerful outcomes.
First, Engineers develop a true quality mindset.
Like a chef who tastes the dish before serving it, Engineers must validate deeply before handing work over. Quality is not something to be outsourced.
Second, QA becomes a force multiplier through automation.
Instead of spending most of the time manually finding defects, QA invests in:
- Stronger test design that covers edge cases
- Automation that protects critical flows
- Fast feedback loops in CI/CD
Automation changes the game.
It allows QA to scale impact without becoming a delivery bottleneck.
It allows teams to move faster with more confidence.
And most importantly, it transforms QA from “bug hunter” into “quality engineer”.
In my experience, this shift is less about tools and more about culture.
Quality becomes a shared responsibility.
Automation becomes the enabler.
And speed no longer has to compromise stability.
