The role of data in better decision making

12 Mar 2026 · Data

By Yerlin Ugarte

Numbers do not decide. People do — if the evidence is honest, visual and close to the operation.

I spent two years as a statistician inside a ministry of education. The job was not to produce charts for their own sake. It was to help a school system see itself: attendance, performance, gaps, trends. The same discipline now sits under the digital products I build. A warehouse, a clinic and a municipal desk all fail in the same way when nobody can answer a simple question with evidence.

Good data work starts with the decision, not with the dataset. Who needs to act, by when, and what would change their mind? From there the method follows: a clean definition, a responsible sample, a visualisation that a non-specialist can read in thirty seconds. Vanity dashboards are a failure of respect.

In product terms this means instrumenting the flows that matter, refusing to collect personal data you will not use, and presenting KPIs next to the work rather than in a separate temple. A travel studio should see which hidden tours convert. A clinic should see which specialties saturate. A town hall should see which procedures people actually start.

If the operation is stuck, write.

If you are building a product, modernizing an operation or exploring a digital idea, I would like to hear about it.
