8+ out of 10 features your team ships will fail. That's not pessimism — it's data. The median organization has an experiment success rate of around 10–15%. Most product teams haven't fully accepted this. So they keep celebrating "code complete" instead of celebrating "we helped users." They keep shipping on flat results, complicating the codebase with features that don't move the needle. The unlock is simple but uncomfortable: if your probability of being wrong is that high, you cannot afford to ship without knowing. Ron Kohavi and Luke Sonnet covers this (and a lot more) in the full webinar: Designing Experiments for Long-Term Growth. Link in the comments.
