Rafał Krząpa | Every Second Costs Money – How Performance Impacts Your Business
Performance issues rarely end as “just a technical problem” - in most cases, they become a direct business cost. System slowdowns, outages, and failures under load can significantly impact revenue, conversion rates, customer trust, and overall user experience. Despite this, performance testing is still often underestimated or treated as a secondary activity until a critical incident occurs.
In this session, Rafał Krząpa will present how the lack of proper performance testing and preparation for real traffic can lead to measurable financial losses and operational issues across different organizations and projects. Using real-world examples and market incidents, he will analyze the business consequences of poor system performance, how these issues were discovered, and why many organizations were not prepared to handle them.
The presentation will also explore how to measure the business impact of performance - from technical metrics to direct financial implications - and how to build a performance testing strategy that acts as a risk mitigation mechanism rather than just a technical validation step.
This session is designed for QA professionals, engineering leaders, and decision-makers who want to approach quality and performance from a business-value perspective, not only through technical KPIs.
