Secara literature, definisi untuk Reliability , Availability dan Maintanibility, dapat juga sbb:
Availability
The ability of an item to be in a state to perform a required function under given conditions at a given instant of time, or in average over a given time interval, assuming that the required external resources are provided.(Uptime)
Reliability
The ability of an item to perform a required function, under given conditions of production, environment, and usage, for a required time interval. (mean time to failure)
Maintainability
Ability of an item under given conditions of use, to be retained in, or restored to, a state in which it can perform a required function, when maintenance is performed under given conditions and using stated procedures and resources. (mean time to repair)
Availability = Reliability X Maintainability
Mudah-mudah dapat membantu.

Reliability : Kehandalan. Menyangkut performa seseorang ato alat.
Availability: Ketersediaan. Ada ato tidak ada.
Kalo orang/alatnya uda ada (available), baru bisa dilihat performa/kehandalannya (reliable).
