What is a reliability function?

The reliability function mathematically defines the probability over the duration. It is a function of time (or cycles, or miles, or whatever unit of time passing makes sense). It is a coupling of probability and time. Always. The function starts with all items working or 100% functioning at time zero.

What does reliability mean in business?
