Critical inputs are materials or components that are required to accomplish one or more key processes. If the supply of a critical input is unavailable, one or more key processes eventually fail. Identify each critical input and the key process(es) it supports. Characterize the tolerable disruption of the critical input, or how long each supported key process can continue operation following disruption of the input, and the amount of time needed to restart the key process(es) after the supply of the critical input resumes.
