Click here for excel form

Description of Form

Part/Assembly Name - Enter the name as listed on the Design FMEA form.

Part/Assembly Number - Enter the number as listed on the FMEA form.

FMEA Number - Enter the number as listed on the FMEA form.

Page - Enter as indicated.

Dates - Enter as indicated. Write revision dates underneath.

Actions - Enter only the recommended actions that will be pursued. Split the description of the action into separate entries if the action consists of several distinct tasks.

Name - Enter the initials of the individual(s) assigned responsibility for implementing the corrective action. If the action involves more than one task, indicate who is responsible for each task.

Page - Enter the page number of the FMEA form on which the recommended action appears.

Line - Enter the line number of the FMEA form on which the description of the recommended action begins.

Committed Completion Date - Enter the date by which the recommended corrective action will be completed. When this cannot be determined, use, for example, the date by which a new product will be tested, measurements analyzed, test started, and so on. Include a note describing what event the date refers to.

Actual Completion Date - Enter the date when the action was implemented, as well as the date after which the part has an acceptable RPN (if different from the implementation date).

Severity - A subjective estimate of how severe the end user will perceive the effect of the failure to be. Based on a scale of 1 to 10, shown:

Ranking	Criteria
1	Negligible severity. It is unreasonable to think that this effect would impact the product's performance. The end user will probably not notice any defect.
2 and 3	Mild severity. The effect would cause only a slight annoyance. The end user will not notice any performance change. Repair can be done at the time of regular maintenance.
4, 5, and 6	Moderate severity. The end user will notice tolerable degradation in performance or appearance. Repair is inexpensive, downtime short.
7 and 8	High severity. The end user will notice an intolerable effect. The effect will occur without warning to an untrained person. Downtime is expensive. Degradation in areas subject to government regulations, but not involving safety.
9 and 10	Potential safety problems. Dangerous effects which occur without warning. Nonconformance to laws.

Note: Avoid assigning more than three different severity rankings to the effects of one failure mode. This facilitates the ranking of likelihood.

Likelihood - A subjective estimate of the probability that the cause, if it occurs, will produce the failure mode and its particular effect. Based on a scale of 1 to 10, shown:

Ranking	Criteria
	Verbal	Defect Rate
1	It is unlikely that this cause would result in the failure mode.	1 in ____
2 and 3	The failure would occur only under rare circumstances.	1 in ____
4, 5, and 6	Failure is somewhat likely.	1 in ____
7 and 8	Failure is very likely.	1 in ____
9 and 10	Almost certain that a failure will occur.	1 in ____

Note: The defect rate that is appropriate for each ranking will vary depending on the product.

Likelihood applies to the effect of a failure mode, too, since every failure mode produces at least one effect. So, for every effect, or group of similar effects, there should be a corresponding likelihood ranking.

Example A: 1 failure mode, 1 cause, 2 effects
A part could potentially break under a certain overload, which produces two effects: a minor one and a major one. In FMEA terminology, this translates into:
Potential failure mode: break
Potential cause: overload
Potential effect: minor effect and major effect
First, the overall likelihood ranking is estimated. The overload is very likely to result in a break, so the overall likelihood ranking would be 8. This is not recorded on the FMEA form.
Next, the likelihood of the failure mode resulting in each effect is estimated. These rankings cannot exceed the overall likelihood ranking of 8. Therefore, the top of the scale temporarily shrinks from 10 to 8. The minor effect is more likely to occur than the major one, so it would rank 6 on the new scale. The major effect is rarely encountered and so would rate a 1. These numbers are recorded on the FMEA form, one above the other, in the same order in which the effects are listed.

Example B: 1 failure mode, 1 cause, 3 effects
Follow the same procedure as in Example A, using an appropriately "shrunken" scale.
For clarity, it is recommended that all three likelihood rankings be entered, even if some are the same. There should be at least as many likelihood rankings for each cause as there are severity numbers. If the severity ranking is the same for all three effects (only one number appears in the severity column), then there may be one or more likelihood rankings.

Example C: More than 3 effects
When there are more than three individual effects, it is sometimes possible to group them together into three or fewer groups. In each group, the effects are similar with respect to severity and likelihood.

Example D: Diversified effects
When there are so many and/or so diversified effects that, even after grouping, more than three groups remain, it is recommended that separate FMEA forms be completed for the excess effects.

In-Place and Planned Cause Preventions or Detections - Identify the measures established to prevent or detect the cause of the failure mode. Examples: product specification, test and calculation reports, inspection and manufacturing specifications, service instructions, information on the engineering drawing, and so on. Include measures that are not yet implemented, as long as they are definitely planned.

Effectiveness - A subjective estimate of how effectively the prevention or detection measure eliminates potential failure modes. It quantifies judgment of the soundness of a design feature or inspection procedure, the validity of a test, the sufficiency of a final test, and so on. Based on a scale of 1 to 10, shown:

Ranking	Criteria
	Verbal	Rate of Cause Occurrence
1	The prevention or detection measure if foolproof. There is no chance that the cause might still occur.	1 in ____
2 and 3	The likelihood of the cause occurring is low.	1 in ____
4, 5, and 6	Moderate likelihood. The prevention or detection method allows the cause to occur occasionally.	1 in ____
7, 8, and 9	High likelihood. The prevention or detection method is effective only sometimes; the cause occurs repeatedly.	1 in ____
10	Very high likelihood. The prevention or detection measure is ineffective. The cause will occur.	1 in ____

Note: The rate of occurrence that is appropriate for each ranking will vary depending on the product.

Resulting RPN - Calculate the new RPN by multiplying the revised severity, likelihood and effectiveness rankings.

Remarks - Enter information that documents traceability, such as references to related actions and identification of memoranda, letters and reports which document the progress and completion of an action.
