Product performance integrated database apparatus and method
First Claim
1. A method of determining product performance comprising the steps of:
- collecting product performance data;
determining the failure mode of detected product failures;
conducting a failure mode effect and analysis procedure to determine a degree of risk of a detected failure; and
developing corrective action to correct the detected failures.

Abstract
A product performance integrated database apparatus and method collects product performance data, determines the root cause of detected product failures and develops corrective action to correct the detected failures. The method determines an initial degree of risk of selected product failures by determining the severity of the effect of each failure and the frequency of occurrence of the effect of each failure. The severity of the effect and the frequency of occurrence are ranked with different ranking values. An initial risk assessment of each failure is the product of the ranked severity value and the selected ranked frequency of occurrence of the failure. Failures exceeding a threshold preliminary risk assessment are subject to the root cause or detected product failure analysis. Once a corrective action for the root cause of failure is determined, a final risk assessment for each corrective action is determined by the product of the initial risk assessment and a determined failure correction validation value.

16. A method of determining product performance comprising the steps of:
-
collecting product performance data;
determining the failure mode of detected product failures;
determining probability of occurrence of each detected failure;
ranking the probabilities of occurrence of each failure to obtain a occurrence value;
determining the severity of effects of each failure;
ranking the severity effects of each failure to obtain a ranked severity effect value; and
determining a preliminary risk assessment of each failure as a product of the ranked severity value and the ranked frequency of occurrence value. - View Dependent Claims (17, 18, 19, 20, 21, 22, 30, 31)
