Data-driven decision-making usually brings to mind dashboards, charts and metrics. What I learned working on business development at Comcai was different: before the product even exists, the most valuable data comes from an honest conversation with a customer.
In our conversations with more than 25 companies, the most useful question wasn't "would you use this product?" but "how do you solve this problem today?" The first invites polite answers; the second reveals real behavior. If time, money or people are already being spent on a problem, there is a real need.
Hypothesis, test, decision
Treating every feature as a hypothesis clarifies decisions: whose problem does it solve, how will we measure it, and at what result do we drop it? Writing down the stopping criterion up front is the hardest and most useful habit.
Proof beats pitch
A proof of concept is more persuasive than the best-prepared deck. A small result a customer sees on their own data moves the conversation from assumptions to facts. In product management, being data-driven starts with having that courage.
