Product Reliability Workshop

Course Description
Broad topic areas covered include predicting reliability, measuring reliability, designing for reliability and improving reliability.  Specific topics include reliability and maintainability prediction, Failure Modes Effects, Criticality Analysis (FMECA), redundancy, the stress-strength relationship, reliability demonstration, reliability growth, reliability data plotting (Weibull), Environmental Stress Screening (ESS), Highly Accelerated Life Test (HALT), Highly Accelerated Stress Screening (HASS) and Failure Reporting, Analysis and Corrective Action System (FRACAS).

Who Should Attend
This workshop is for anyone who knows nothing about reliability, knows some basic things about reliability and wants to learn more, or who has a working knowledge of reliability and wants to fine tune their skills.  No previous knowledge about reliability is assumed.

Learning Objectives
A participant in this workshop will learn:

  • What reliability is, and how it helps a company’s bottom line
  • Tasks associated with Design For Reliability, and where in the product development/life cycle to best apply them
  • How to predict how often a new design will fail, how long it will take to fix if it does fail, and how these both relate to availability (product is up and working when you need it)
  • What is the difference between random failure and wear-out
  • How to determine if failure rate is decreasing, constant or decreasing
  • The relationship between strength and stress (load), and how de-rating improves reliability
  • How to determine which failures are the most critical
  • How to measure and analyze reliability data, in both demonstration and growth tests
  • How to improve mission survivability with redundancy
  • How to improve the reliability of a design using Highly Accelerated Life Test (HALT)
  • How to screen for production defects using Environmental Stress Screening (ESS)
  • How to leverage the results of HALT to turn ESS into Highly Accelerated Stress Screening (HASS)
  • How to learn from failures, and use what you have learned to prevent their re-occurrence (Failure Reporting, Analysis, and Correct Action System (FRACAS)
