Current Design/Machinery Controls
Design/Machinery Controls are methods, techniques, devices, or tests used to:
- Prevent the Cause/mechanism or Failure Mode from occurring, or reduce rate of occurrence.
- Detect the Cause/mechanism and lead to corrective design actions, and
- Detect the Failure mode.
Identification of Design/Machinery Controls should begin with those failure mode combinations that have the highest Severity and Occurrence ratings.
Design/Machinery Controls used to prevent the cause/mechanism or failure mode/effect from occurring, or reduce their rate of occurrence may affect the Occurrence rating. If this is the case, these Controls should be taken into account when estimating the Occurrence rating (Column 15). Only Controls that are used before engineering release are to be considered when estimating the Detection rating.
