Desing for Reliability

Desing for Reliability

1. Failure Analysis

   • Iterative process that influences desing by identifying failure modes. Assessing their probabilities occurrence and their effects on the system
     • It is and inductives process that attempts to answer three important questions:
       • 1) What could go wrong? 2) How bad might it be? 3) What can be done to prevent it

2. Steps

   • Product Definition
     • Identification of Failure MOdes
       • Determination of Cause
         • Assesment of Effect
           • Estimation Of Probability of occurence
             • Estimation of detecting a defect
               • Classification of severety
                 • Computation of Critacally (Risk Priority Number)
                   • Determination Of Corrective Action.
