Build your learning vault

Individual experiments create insights. A systematic learning repository creates competitive advantage. Teams that capture and share learnings outperform those that repeatedly rediscover the same truths.

Build a searchable repository of experiment documentation, results, and insights. Include failed experiments alongside successes. Failed tests often contain the most valuable warnings about what doesn't work. Tag experiments by hypothesis type, user segment, and feature area to enable cross-team learning. Make accessing past learnings part of the experiment planning process.

Transform your repository from a graveyard of documents into a living resource. Schedule regular reviews of past experiments to identify patterns. What assumptions do you repeatedly get wrong? Which user segments consistently surprise you? Create learning summaries that distill insights from multiple experiments. Share these broadly to prevent other teams from repeating mistakes. Your learning vault becomes more valuable over time, compounding the return on every experiment you run.
