A good experimentation program is much more than running A/B tests. The goal is to create a reliable system for learning what actually improves your product and business, while avoiding decisions based on noise. A practical framework looks like this: 1. Start with clear business goals Tie experiments to a small number of company objectives, such as: - Increase trial-to-paid conversion - Improve
