6.Recommended Solutions Double-click on template and enter data with Visio Approval needed by:
Scale: 1-None 2-Somewhat 3-Moderate 4-Very 5-Extreme
Cost BenefitAnnualized cost of problem 1 $0.00Percent of problem reduction 2 0%Cost of proposed solution 3 $0.00
Total first year savings (1 x 2 - 3) $0.00

SEVERITY EVALUATION CRITERIA
Effect Criteria: Severity of Effect RankingHazardous- 10
Hazardous- 9
With warning
Very High System / item inoperable, with loss of primary function 8
High 7
Moderate 6
Low 5
Very Low 4
Minor 3
Very high severity ranking when a potential failure mode effects safe system operation
Without warning
and/or involves noncompliance with a government regulation without warning
Very high severity ranking when a potential failure mode effects safe system operation
and/or involves noncompliance with a government regulation with warning
System / item operable, but at a reduced level of performance. Customer dissatisfied.
System / item operable, but comfort / convenience item(s) inoperable. Customer experiences discomfort.
System / item operable, but comfort / convenience item(s) operable at a reduced level of performance. Customer experiences some dissatisfaction.
Fit & Finish / Squeak & Rattle item does not conform. Defect noticed by most customers.
Fit & Finish / Squeak & Rattle item does not conform. Defect noticed by average customers
