The first rule about Project Mayhem is…
you don’t ask questions about Project Mayhem.

A new car built by my company leaves somewhere traveling at 60 mph.
The rear differential locks up.
The car crashes and burns with everyone trapped inside.
Now: should we initiate a recall?
Take the number of vehicles in the field, A, multiply by the probable rate of failure, B, multiply by the average out-of-court settlement, C.
A times B times C equals X.
If X is less than the cost of a recall, we don’t do one.
