environmental consequences?
Hidden consequences?
Operational consequences?
Non-operational consequences? N N N Y Y Y Y
CBM? Can CBM reliably detect the 'failing' state early enough to reduce the probability of a multiple failure to a tolerable level? Does it make economic sense to perform this task at the frequency required?
CBM? Can CBM reliably detect the 'failing' state early enough to reduce the failure's probability and/or its consequences to a tolerable level? Does it make economic sense to perform this task at the frequency required?

TBM? Is there an age (useful life) at which the probability of failure due to this failure mode increases rapidly, and do most items survive to this age? Can a routine (TBM) task reduce the multiple failure's probability and/or its consequences to a tolerable level? Is the task economiically feasible?

Two? Will the combination of 2 or more TBM and CBM tasks be effective (avoid or reduce the safety consequences to a tolerable level)? Are they applicable (practical and economically feasible)?
NSM? No time nor condition based activities need be scheduled.

Failure detection? Is a detection task applicable? Will it reduce the multiple failure's probability to a tolerable level. Is it practical and economically feasible to perform the task at the required frequency? N N N N
Redesign of the asset and / or its operational procedures is optional.
Redesign of the asset and / or its operational procedures is optional.
Redesign is mandatory if the multiple failure can have health, safety, or environmental consequences. Optional otherwise.
