Would adding more metrics fix a rating for machine buyers?
From MCC-001, an essay: a hypothesis, not a measurement.
The short answer
Not necessarily. The essay argues that a score for every task, operating condition and tolerance for failure would restore much of the detail the rating compressed, so a rating's simplicity depends on how much of the buyer's problem can safely be left out.
As published in the issue
Adding metrics does not necessarily resolve this. A score for every task, operating condition and tolerance for failure would restore much of the detail the original rating compressed. The apparent simplicity of a number depends on how much of the buyer’s problem can be safely left out.

Why it matters
Adding dimensions to a rating trades its simplicity away without recovering the record underneath. A buyer that needs the detail may be better served by the evidence than by more scores.
