# Four Measurement Lanes
Source: https://humanspark.ai/frameworks/four-measurement-lanes/

*Four kinds of number, none of which may impersonate another.*

**When to use:** Setting baselines before a test, and reading the results after it.

Activity

Is the tool being used?

Work

Is the work itself done differently?

Business

Did a number the business cares about move?

People

What did the change do to the people doing it?

> **Baseline first:** Each lane needs a baseline taken before the test, and the people lane counts in the verdict rather than beside it.
