Fine-grained measurement is useful when you have options for fine-grained action.

You don't need a chip to tell you that the soil is dry, but if you can use that chip to regulate drip irrigation that can apply substantially different flow to different plants, then you can get a not-too-much, not-too-little watering even if you have a big variation in conditions.

You don't need a big analysis to acknowledge that everybody knows that a particular competitor has lower or higher prices and adjust your pricing; but doing that continuously on a per-product basis does require data and analysis.
