Demonstrating Product Reliability - Sample Sizes and Testing Times

Duration: 60 Minutes
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.
Reliability Metrics
Instructor: Steven Wachs
Product ID: 508137
Objectives of the Presentation
  • Understand reliability metrics/statistics
  • Identify alternatives for demonstrating that reliability targets have been achieved
  • Manage tradeoffs between sample sizes and testing times
  • Develop reliability test plans that consider the tradeoffs between sample sizes, testing times and risks of not passing the test
Why Should you Attend
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.
