Is it time to refresh your metrics?

You study, you brainstorm, you have endless meetings to find the best metrics—and then spend years accumulating, trending, and applying data. But while a metric can be long-lived, they're unlikely to be immortal.

If you're lucky, something dramatic happens to highlight the need for a new measure—such as when Lufthansa developed thinner seats which provided more usable space in less “seat pitch,” throwing a wrench in one of the most common cabin metrics.

But more often, it’s simply an accumulation of technical, marketplace, and fashion shifts which might have you coming up with a slightly different set of metrics—if you thought about it today.

So how long has it been since yours had a check-up?
