The Real Value of Testing
The most valuable bugs are the ones you never find—because they were prevented before they were ever built.
Too often, testers are brought in late, when requirements are set and design decisions already made. At that point, finding defects is useful—but the biggest risks have often already been introduced.
After nearly 30 years in testing, I’ve seen the same pattern again and again: many of the most costly issues are visible early, during requirements and design—if you know what to look for.
In this talk, I’ll show how testers can use their experience to recognize these risks early and influence better decisions. By asking the right “what if” questions, challenging assumptions, and connecting requirements to real customer behavior, testers can prevent problems instead of just detecting them.
You’ll learn practical techniques to:
- identify gaps between requirements and real-world use
- recognize design choices that may lead to confusion or failure
- bring customer and business perspectives into early discussions
By shifting focus from defect detection to defect prevention, testers can move from being bug-finders to becoming trusted partners in shaping quality, reducing rework, and improving customer satisfaction.
Because the real value of testing isn’t what you find—it’s what you help avoid.
