What is sequential testing? When is it most effective, and when is it least effective, for accessing a system\'s reliability.

Solution

What is sequential testing:

Sequential testing often provides a more efficient method to verify equipment reliability achievement.

When is it most effective:

Reliability hazard analysis, failure mode and effects analysis (FMEA), fault tree analysis (FTA), Reliability Centered Maintenance, (probabilistic) load and material stress and wear calculations, (probabilistic) fatigue and creep analysis, human error analysis, manufacturing defect analysis, reliability testing, etc. It is crucial that these analysis are done properly and with much attention.

When is it least effective:

manufacturing variances can be effectively reduced, six sigma tools may be used to find optimal process solutions and may thereby also increase reliability. Six Sigma may also help to design more robust related to manufacturing induced failures.

Root cause analysis that identifies the causal relationships involved in the failure such that effective corrective actions may be implemented. When possible, system failures and corrective actions are reported to the reliability engineering organization.
