It's the tradeoffs, stupid! - How experimentation helped us to shape our product strategy

In a mature company like Zalando, true product innovation isn't about finding easy wins; it's about navigating complex tradeoffs. As we improve one key metric—like increasing conversion rates—it's likely to negatively impact another, such as customer lifetime value or return rates. The days of "all-gain, no-pain" improvements are long gone. This talk will explore how we use a sophisticated experimentation framework to precisely surface these tradeoffs and understand the ripple effects across our entire business. We'll show how we move beyond simple A/B testing to uncover the nuanced relationships between different metrics, allowing us to make informed, data-driven decisions that shape our product strategy for long-term sustainable growth.
