Prototyping at Harrah's

Harrah's offered 2 groups of customer either:
- a $125 package, including a free room, 2 steak dinners, and $30 in chips
- $60 in chips

The $60 offer generated more gambling revenue than the $125 offer.

Including unavailable metrics

At DaVita, if a metric is considered important, but the data isn't currently available, the metric is included on reports anyway with the notation 'not available'. The persistent mention of important measures that are missing helps motivate the company to figure out ways to gather that information.

DaVita is $2bn Californian manufacturer of kidney dialysis machines.
