We in the flight safety department at a major carrier were once characterized as a "profit center" and had to show where our activities provided reasonable expectation of profit.
I'll have to agree that sounds far out. However there is nothing wrong in applying measurements to one's effectiveness.
From a safety standpoint I can think of at least two measures that might be considered
"minor" safety related (against the FARS) incidents per flight hour
cost of insurance vs cost of doing business.
