🔎 Interesting things you might have missed
Matt Gershoff wrote Privacy Engineering in A/B Testing and explains how Conductrics is designed with privacy by design principles in mind. They only collect and store the minimum amount of data necessary to run the test. Conductrics does this by de-identifying and aggregating data as it is collected. Interesting approach. READ
Optimizely published an ebbok with lessons learned from running 127,000 experiments. Very nice overview and insights. In response Ronny Kohavi wrote a review with the good and the
badthings to improve.Matteo Courthoud wrote Understanding Group Sequential Testing and explains how to run valid experiments, with peeking and early stopping.
Eppo added Certified Metrics. Which ensures that “core metric definitions are in sync across experimentation in Eppo, BI, and other data platforms, all managed via GitHub.”
Ronny Kohavi ran a poll where he asked about the best reasons NOT to A/B test. Winner: not enough users.
Datapoint: “At Spotify, we've been exercising our experimentation muscle for more than 10 years. We now have over 300 teams running tens of thousands of experiments annually.”
💬 Melanie Kyrklund: My Experimentation Career Journey
Today’s interview is with Melanie Kyrklund, Global Head of Experimentation at Specsavers. Melanie describes herself as a veteran experimenter who is still learning every day, even after 15 years in this field. She's half British, half Swedish Finn, was raised in Italy (Rome) and has been calling Amsterdam home for a long time.
I feel the best learning comes from living through the challenges and thought processes that give rise to solutions yourself. — Melanie Kyrklund
