The discipline of the number

Most plants run on unaudited numbers.

We settle disputed numbers, explain drifting ones, and verify the ones a decision rests on.

Every figure in your board pack came from a sample. Almost none of them carry a stated uncertainty.

Measurement assurance

Is the equipment capable of taking an unbiased sample?

How much uncertainty does the reported number actually carry?

Is there a systematic error, proven rather than asserted?

Sampling is one of the largest sources of error in any reported figure and the least audited. It is where we work.

That is the whole of the first conversation.
