Guides for making a calculation operational.
These guides explain method choice, definition boundaries, and questions to ask before a metric becomes a decision.
Reliability growth and Duane model
Plan and interpret a power-law growth program.
Accelerated testingAccelerated life testing model selection
Match stress models to failure mechanisms and test decisions.
MetricsMTBF vs MTTF vs MTTR
Definitions, use cases, and common misuse.
ReadinessEquipment availability
Choose the correct availability boundary.
ArchitectureReliability block diagrams
Model success paths and dependencies.
Life dataUnderstanding Weibull analysis
Shape, characteristic life, and uncertainty.
PerformanceOEE loss categories
Turn a score into loss ownership.
EconomicsDowntime cost framework
Build a traceable consequence model.
DecisionRepair vs replace framework
Compare future risk and economics.
MROMRO safety stock planning
Balance service risk and carrying cost.
Work managementMaintenance planning and scheduling
Keep planning, scheduling, execution, and review distinct.
Maintenance dataCMMS data readiness
Build trustworthy asset and work-order records before relying on KPIs.
Fault investigationIntermittent fault and NFF investigation
Preserve transient evidence, compare history, and prepare bounded reproduction tests.
MRO forecastingIntermittent spare-parts forecasting
Audit sparse history, validate baselines, and govern planner overrides.
Operating exposureEquipment operating profile analysis
Reconstruct state, load, excursion, and rate evidence before interpretation.
Method before dashboard.
Use a calculator to make arithmetic transparent, then use a guide to test its decision boundary. The reference desk keeps core definitions close at hand.
