Quality isn't a phase you add before shipping — it's a discipline that needs to run through every stage of development. And the data backs this up: fixing a bug in production costs 10x more than fixing it during requirements. Yet 56% of all defects originate in the requirements phase.
I just published a structured overview of Software Quality Assurance that breaks down:
- How verification and validation work (and why they're different)
- Testing strategies: when to use white-box vs. black-box
- Why quality processes fail in most organizations
- The complete testing lifecycle: unit → integration → system → acceptance
- Practical frameworks for building quality into your process from day one
Whether you're writing code, managing QA, or leading an engineering team, this gives you the framework to understand how quality actually fits into real software development.
