Software reliability testing is being used as a tool to help assess these software engineering technologies. Availability is typically given as a percentage of the time a system is expected to be available, e.g., 99.999 percent ("five nines"). It takes into account the repair time & the restart time for the system. Simply put availability is a measure of the % of time the equipment is in an operable state while reliability is a measure of how long the item performs its intended function.
