Reliability Across the Product Lifecycle
Verification & Qualification
Generate analytical and test evidence against defined reliability and lifetime requirements.
Purpose & Benefit
Reliability Support at This Stage
Define the test question before committing laboratory time. Link stresses, sample size, duration and acceptance criteria to the intended application and relevant mechanisms.
Reliability Activities
Select the Support Your Project Needs
Choose an individual activity or discuss a coordinated programme. Activities are selected according to the product risks and available evidence.
Reliability Test Planning
Define what to test, at which stresses, for how long and with how many samples.
ExploreAccelerated Life Testing
Develop accelerated tests linked to relevant failure mechanisms and use conditions.
ExploreAccelerated Degradation Testing
Use measurable performance change to investigate lifetime before complete failure occurs.
ExploreReliability Demonstration Testing
Plan a test that can demonstrate a specified reliability target at an agreed confidence level.
ExploreEnvironmental & Application Qualification
Define environmental and application-specific qualification evidence.
ExploreDesign of Experiments
Structure experiments to separate the effects of design, material and process factors.
ExploreWeibull & Life Data Analysis
Turn test and field lifetime data into reliability estimates with a defensible statistical basis.
ExploreFailure Analysis
Investigate physical failure mechanisms and support corrective action.
ExploreReliability Growth
Track whether engineering changes are reducing failures as development or operation progresses.
