Conflicting definitions and fragmented metrics erode trust and slow innovation. Real impact only happens when organisations establish clear, consistent metrics, guardrails, and decision-ready products that teams adopt at scale. At Booking.com, scaling experimentation and measurement required:
• Defining golden metrics and guardrail frameworks that teams could rely on.
• Building the Impact Aggregator approach, turning ad hoc analyses into reusable, decision-ready products.
• Developing platforms for measurement and experimentation that balance safety, control, and innovation.
• Leading the change management journey to align leadership and embed new ways of working across a large number of teams.
The outcome? Clearly defined, shared metrics, platforms that scale, and decisions that are faster, safer, and more consistent.
