Data vs. Insight
The words get used interchangeably, but they're different animals. Data is a fact. An insight is the why behind the fact, sharp enough to suggest an action.
Everyday example — the doctor's visit
"Your temperature is 39°C" is data — a true fact, but on its own it doesn't tell you what to do. "You have a throat infection, so take this antibiotic for a week" is an insight — it explains why you have the fever and points to an action. A thermometer full of readings is useless until someone works out what's causing them. Product teams drown in the thermometer readings (dashboards) but what they actually need is the diagnosis.
An example ladder
Data: "40% of users abandon checkout at the payment step."
Finding: "Abandonment spikes right after the order total updates."
Insight: "Users abandon because the shipping fee appears only at the last step — the total jumping 20% at payment feels like a trap."
Data describes. Insights explain — and an explanation tells you what to try next.
