Joël Gastelaars
Working on the edge of Business Strategy and Data Science. For me, it is all about converting business challenges into scalable data (science) solutions to create tangible value for the client. Currently leading the implementation of a company-wide experimentation & measurement platform in the airline industry and consulting on organizational change.
Besides being a "techy", I like to make sure everyone understands what we do, why we do it and how it adds value for their business.

Conventional A/B testing often falls short in industries such as airlines, ride-sharing, and delivery services, where challenges like small samples and subtle effects complicate testing new features. Inspired by its significant impact in leading companies like Uber, Lyft, and Doordash, we introduce the switchback design as a practical alternative to conventional A/B testing. By addressing small sample size limitations and the need to detect subtle effects quickly, this approach boosts statistical power while reducing variability and interference. We guide the audience through the challenges of marketplace experimentation and implementing this approach, period length optimization and switch frequency using a case study from the airline industry.
