Abstract

A method for use in a system for prioritizing risks associated with the design and manufacture of products involves performing a failure mode detection analysis. Functions of the product and/or of the process and the effects of undesirable events related to malfunctions are characterized, and potential failure modes and causes for the effects are identified. The features of the product/process that are responsible for the undesirable effects are determined. Severity, occurrence and detectability of the undesirable events are evaluated using specific measures designed to encourage score keeping, and risk factor numbers are computed. The resultant numbers are ranked and prioritized for a set of selected functions. Risk reduction may then be performed through engineering activities directed to remedy causes associated with the malfunctioning features. Failure mode detection analysis may be updated to continue incremental and focused improvements to the product and/or process. The method permits the capture of potential failures before they reach the field and the customer.
