UNDERSTAND THE CONCEPT
A reliability, availability and maintainability study begins with the question the owner needs answered. Define the system boundary, required output, operating modes, mission or reporting period and what constitutes loss of function. A result without this context cannot be meaningfully compared.
Build an assumption register covering data sources, repair resources, spares, common dependencies and capacity constraints. Compare a baseline with named alternatives using the same basis. Sensitivity analysis helps identify which uncertain inputs matter most and where better evidence is worth collecting.
Questions to take back to your team
- What decision must the study support?
- Which dependencies lie outside the ownership boundary?
- Which uncertain inputs dominate the result?
