Training Overview

Product Reliability requirements must be satisfied like all other performance requirements prior to product launch. However, since reliability is a function of time, the methods for verifying that reliability performance has been verified differ than for most other performance characteristics. This webinar will present several approaches for verifying that reliability targets or specifications have been achieved at the desired level of confidence. Specifically, approaches using time-to-failure data to estimate reliability metrics as well as demonstration tests, where minimum reliability may be demonstrated with zero or few failures are discussed. 

 This webinar provides methods that allow the risks of field failures due to inadequate designs or misunderstanding of product use conditions to be managed. Also, the webinar provides options to verify and demonstrate that customer reliability requirements have been achieved. 

Course Objectives

  • Understand the different between reliability estimation and reliability demonstration
  • Understand methods for estimating reliability
  • Develop reliability test plans that optimize available resources (e.g. testing time, number of units)
  • Achieve confidence that product will perform successfully in the field
  • Demonstrate that customer reliability requirements have been met
