Illustrative, not evidence.

Scenario. A grower designs a drip irrigation controller for a greenhouse. Soil moisture, water pressure and supply temperature vary from day to day. The team tests the controller with varied inputs: noisy sensors, low pressure, a cold-water inlet. The water delivered to each plant changes little across the tests.

• P27: The design aims at a result that changes little when inputs vary. Tests with varied inputs show stable results.
