Back
Failure is unlikeky. No known failures associated with almost identical processes.
Process is in statistical control. Only isolated failures associated with almost identical processes
Process is in statistical control but with isolated failures. Previous processes have experienced occassional failures or out-of-control conditions.
Process is not statistical control. Similar processes have experienced problems.

Back
The process automatically detects failure. Controls will almost certainly
detect the existance of a failure.
Controls have a good chance of detecting the existance of a failure
Controls may detect the existance of a failure
Control have a remote chance of detecting the failure
No known control(s) available to detect failure mode
