Test and Scale

Explore options cheaply, then commit decisively — especially when reporting logic, definitions or service models are changing.

The principle explained

Cartoon: route-testing expedition metaphor for Test and Scale

Test and Scale means exploring multiple possible routes to success in a cheap, safe, repeatable way, then moving decisively once the evidence is clear.

In the expedition metaphor, the team does not send the whole group onto dangerous ice to find out whether it is safe. They use drones, probes, route markers and small tests to identify the best route. But testing is only half the principle. Once the right route is clear, the team must be ready to move quickly and commit properly — promoting prototypes into products, not leaving pilots running forever.

I would not treat a new data model as automatically meaning the same thing in a different format. I would test whether it still answers the service question — then scale what works.

The principle in practice

Test and Scale is how I would avoid betting the whole six-month secondment on the first plausible solution. I would run small tests with real users, compare old and new logic side by side, and be willing to stop ideas that look tidy but mislead — especially while definitions are still moving during migration.

A good Business & Performance approach does not mean building a permanent dashboard for every suggestion. It means keeping a visible portfolio of ideas, deciding what deserves further investment, and scaling only when managers actually use the output to make decisions.
