THE POST-TEST DEBRIEF: A NEW SUPERPOWER FOR GROWTH DESIGNERS

Summary from the TLDR Design newsletter

Adobe's growth design team created the "Posttest Debrief," a 30-minute session held after each A/B test, which turned scattered data into clear customer insights and strategy. It addressed the issue of buried test results, which made it challenging to connect findings or build on past learnings. By bringing together designers, product managers, and analysts on a shared whiteboard, teams moved beyond win-or-lose metrics to uncover deeper behavioral patterns. This method accelerated planning, refined hypotheses, and established a growing body of insights to prevent repetitive testing.
