Application of Reliability Demonstration Testing to the Product Development Life Cycle

Reliability Demonstration Testing (RDT) is an effective process to identify and predict top field failure modes and to predict product Annual Failure Rate % (AFR%) during the product development cycle. An efficient RDT process allows product development teams to be proactive during design development rather than reactive after the product release to costly design warranty issues in the customer field. This presentation discusses where and how the RDT process fits within a product development Reliability/Quality plan applied to medical instruments developed at Cardinal Health. Five key RDT product development cycle areas are reviewed:

  1. Component or subsystem level RDT process
  2. System Reliability Block Diagram (RBD) model
  3. System level RDT process
  4. Product reliability metrics and warranty/repair cost impacts
  5. RDT process feedback from first year field warranty/repair data analysis
