The totalĬost can be predicted from the conditional probability analysis and cost per Statistical and data analysis tools to guide management decisions. In each case, there is an assessment of what data is availableĪnd what assumptions need to be made, along with consideration of available Rationally consider suspended samples, requiring a suspension strategy. Of appropriate life distribution models with clean failure mode data (i.e.,Ĭlassified into unmixed distinct failure modes) as well as a means to Involving a conditional probability analysis. The dual nature of automotive warranty risk related to time and usage, Has been employed for some time and has been further enhanced by considering Transition to a field durability issue, the prediction of warranty risk fromĪ diluted “quality spill” (i.e., a manufacturing problem not detectedīy existing manufacturing controls), and other issues. The method has proven successful in detecting an early Led to additional insight in predicting organizational risk and drivingĮarlier action. Of generating intelligence from automotive warranty data and provides anĪpproach supported by examples of situations where analyzing warranty data This article promotes an overall philosophy Failure distribution analysis is recommendedįor addition to the standard warranty analysis tool set. To best predict business risk involves aĬonditional probability analysis to account for the usage truncated warranty With customer usage and application-specific data to more quickly detect and Prediction evaluated in light of data and assumptions to identify theĪppropriate technical and business actions.) The method involvesĮstimation of the failure distribution from available warranty data coupled Requirements hence incidents must be investigated and qualified, with any Not always represent a product issue or non-conformance to product Performance against an established warranty reserve. Of analysis can be used to estimate the warranty reserve or measure Issues early in the production cycle, and as the exposure matures this type ThisĪrticle highlights an analysis method to better detect potential product Warranty data is commonly tracked andĪnalyzed in the automotive industry but there are significant businessīenefits to be gained through swifter reaction to warranty issues. Tremendous amount of money, help preserve a business reputation and increase
In theĪutomotive industry, an early response to an emerging issue can save a Manufacturers desire to address business risks as early as possible. All are worthwhile aspects of standard business intelligence. Managing business costs, maintaining business and assuring success in the Incorrectly but undetected by manufacturing controls, etc., with an eye to Warranty return analysis for automotive components usuallyĬenters on looking for trends, manufacturing spills, components built
