Data tells you what happened. Users tell you why.
Do not hesitate to speak to your users. They can help more than you think.
Product decisions rely heavily on data. Funnels, drop-offs and click maps are useful because they tell you what happened inside the product. They show you where users moved, where they stopped and what they interacted with. But they rarely tell you why.
That missing info is mostly with your user. Users carry context that data cannot capture — what they were trying to do, what they expected to happen and what confused them along the way. Without that context, product teams often end up interpreting behaviour through assumption.
And this is where product teams often go wrong. Data creates confidence because it feels objective, but it is incomplete. Without speaking to users, it is easy to mistake patterns for explanations and optimise for the wrong thing.
Data gives you signals. Users give you meaning. Good product decisions need both.
