Zero Bug Policy: When a Metric is Not an Enemy But an Ally of QA

QA engineers often perceive a Zero Bug Policy (ZPB) as a source of stress and additional reporting overhead. But what if we use this metric as a tool to identify and solve systemic team problems?

In this talk, I'll share practical experience of transforming chaos in bug management into a controlled process. Using the “Order and Payments” stream at Yandex Lavka as a case study, I'll demonstrate how we reduced ZBP from 1000 to 150 over 9 months while decreasing QA workload and increasing development team engagement.

I'll explore five key principles of a systematic approach: process regularity, priority transparency, focus on user problems, measurability of improvements, and involvement of the whole team. I'll present specific tools: from dynamic prioritisation of DUTY tickets to DSAT analysis of customer dissatisfaction.

The talk will be useful for QA engineers and leads who want to turn bug handling from a constant source of stress into an efficient process.
