The One Where Sustainability Crashed the Sprint Planning

For years, software teams have carefully balanced performance, reliability, security, and cost. Then Generative AI showed up and invited another guest to the meeting: sustainability.

As organizations race to adopt AI-powered solutions, the energy demands of modern cloud infrastructure are growing at an unprecedented pace. Training and running large language models now requires enormous computational resources, creating a hidden challenge for engineering teams: how do we continue to innovate without overwhelming our budgets, our infrastructure, or the planet?

In this keynote, we'll explore the surprising intersection between Quality Engineering, Performance Engineering, and Sustainable Software Development. Through real-world examples, we'll uncover the environmental impact of AI workloads, examine why energy consumption should be treated as a quality metric, and discuss practical strategies for building systems that are both performant and responsible.

You'll learn how green coding practices, sustainable architectures, and energy-efficient engineering decisions can reduce operational costs while supporting corporate sustainability goals. More importantly, you'll discover why sustainability is no longer a concern reserved for executives and ESG report...

it's becoming part of every engineering team's Definition of Done.

Because sooner or later, sustainability will join your sprint planning. The only question is whether it arrives as a strategic initiative or as your next cloud bill.

Why Software Testing Keeps Solving Problems Nobody Really Has

For decades, software testing has focused on finding defects, increasing coverage, and improving efficiency. Yet despite better tools, smarter automation, and increasingly sophisticated engineering practices, many quality problems remain stubbornly unsolved. Perhaps the issue is not that we fail to find the right answers—but that we often begin by asking the wrong questions. Too frequently, we optimize metrics instead of outcomes, validate assumptions instead of challenging them, and invest enormous effort solving problems that were never the real problem in the first place.

This keynote explores what software testing can learn from philosophy, psychology, and science to rethink the way we approach quality. Drawing inspiration from thinkers such as Karl Popper, Daniel Kahneman, Leonardo da Vinci, and Russell Ackoff, we will examine how critical thinking, cognitive biases, observation, and problem framing shape the effectiveness of testing far more than any tool or methodology. Rather than introducing another testing framework, this session offers a different perspective: the future of software quality belongs not to those who find more defects, but to those who define better problems before anyone starts searching for solutions.
