Quality Assurance: Build Quality Into Your Development Process

There’s a fundamental difference between testing and quality assurance. Testing finds bugs after code is written. Quality Assurance prevents bugs from being written in the first place. While testing is essential, true quality comes from building it into every step of your development lifecycle.

At Async Squad Labs, we help teams establish robust QA processes that catch issues early, reduce technical debt, and create a culture where quality is everyone’s responsibility—not just the QA team’s.

Why Quality Assurance Matters

The Cost of Poor Quality

Software quality problems have real business consequences:

• Technical Debt: Poor quality code slows future development by 20-40%
• Customer Churn: 61% of users uninstall apps after experiencing bugs
• Developer Productivity: Teams spend 42% of time on maintenance and bug fixes
• Brand Damage: Quality issues erode customer trust and reputation
• Hidden Costs: Quality problems compound over time

The Value of Quality Assurance

Investing in QA delivers measurable returns:

• Faster Development: Prevent issues rather than fix them later
• Lower Costs: Quality issues cost 30x more to fix in production
• Better Products: Deliver software that delights users
• Team Morale: Developers prefer working on quality codebases
• Competitive Advantage: Quality sets market leaders apart

Quality Assurance vs. Testing

Testing

• Reactive: Finds bugs after they’re written
• Focused on specific features or components
• Primarily the responsibility of QA/testing team
• Happens in specific phases of development
• Measures what was built

Quality Assurance

• Proactive: Prevents bugs from being introduced
• Focused on the entire development process
• Everyone’s responsibility
• Continuous throughout development
• Ensures we’re building the right thing

Both are essential, but QA provides the foundation that makes testing more effective.
