Yes, but I guess my objection is that if it attempts to measure everything then we can't really tell what it measures in what proportions.

Yep, that’s a feature of end to end measures, like company revenues, vehicle fuel efficiency, or human life expectancy.

The customer may not care what the internal contributions are to such a measure. Instead it represents the customers’ overall values in some way.

Ok. I think you convinced me based on those. I withdraw the objection.
