Order of Magnitude Metrics

My brother Bob runs an accounting firm back in Canada. He's a sharp business person and has a real gift for speed-of-light billing and more importantly, collecting.

Bob classifies his receivables in a 30/60/90 report.

To most accountants, that means 30 days, 60 days and 90 days outstanding receivables.

Except Bob measures his receivables in minutes.

What changes would occur at your workplace if you changed the order of magnitude of your business metrics?
