Potential outcomes

What Potential outcomes captures

Potential outcomes is a statistical or measurement concept used to describe, compare, or interpret engineering data. In practice, the useful question is what the value represents, which observations contribute to it, and what alternative explanations remain. Write down the unit, inclusion rule, and aggregation before comparing results.

An engineering example

A company studies whether a workflow change affects review time. The potential outcomes helps define the causal question or comparison, while the team records assignment, timing, exposure, and the assumptions needed to interpret the contrast.

Limits and interpretation

Causal interpretation requires a credible assignment or comparison design; a named method cannot replace its assumptions. Spillover, selection, measurement error, and changing conditions may change the estimand.

Use the result responsibly

Pair this concept with the underlying observations, sample count, comparison condition, and uncertainty. Preserve the query or calculation version when the result informs a release, staffing, reliability, or AI adoption decision. If the definition changes, mark the boundary so a trend is not confused with a measurement change.
