Although a primary objective of reliability analysis is to improve product reliability, there are many possible reasons for collecting and analyzing reliability data. Several examples are the following:

  • Assessing product reliability in the field
  • Predicting product warranty costs
  • Estimate replacement part/spares requirements
  • Assessing the effect of a proposed design change
  • Demonstrating product reliability to customers or government agencies
  • Comparing components from multiple suppliers
  • Comparing components from different production periods, operating environments, or materials
  • Improving reliability through the use of laboratory experiments

Participants will gain awareness of the overall methodology for setting reliability targets, estimating product reliability from test data and/or field data, and determining whether or not reliability targets are achieved. Methods for estimating the reliability of subsystems and systems are also discussed. Participants will also learn how to calculate sample sizes for reliability testing and utilize reliability models to develop forecasts of future failures (e.g. warranty forecasts).


Why you should attend :

  • Understand reliability concepts and unique aspects of reliability data
  • Understand underlying probability and statistical concepts for reliability analysis
  • Develop competency in the modeling and analysis of time-to-failure data
  • Understand reliability metrics and how to estimate and report them
  • Estimate reliability of subsystems and systems
  • Determine if reliability specifications are met (at specified confidence level) or whether design improvements are required
  • Develop competency in the planning of reliability tests (excluding ALT)
  • Analyze existing warranty data to predict future returns
  • Develop awareness of more advanced topics in Reliability

Who will benefit:

  • The target audience includes anyone with a vested interest in product quality and reliability
  • Product Engineers
  • Reliability Engineers
  • Design Engineers
  • Quality Engineers
  • Quality Assurance Managers
  • Project / Program Managers
  • Manufacturing Personnel
