RCM-Style Decision Worksheet

Conduct structured Reliability Centered Maintenance decision audits on critical systems.

What are the 7 questions of SAE JA1011 Reliability-Centered Maintenance?

Standardized under SAE JA1011 / JA1012, RCM evaluates: (1) Functions, (2) Functional Failures, (3) Failure Modes, (4) Failure Effects, (5) Failure Consequences (Hidden, Safety, Environmental, Operational, Non-Operational), (6) Proactive Tasks (On-condition, Scheduled restoration, Scheduled discard), and (7) Default Actions (Run-to-failure or Redesign).

SAE JA1011 Decision Worksheet

All 7 questions of classical Reliability-Centered Maintenance

Total Failure Modes

Hidden Failures

Operational Loss

Safety & Environmental

Subsystem / Function	Failure Mode & Effect	Consequence	Selected Task & Interval	Role	Action
Deliver 150 m³/h water at 60 bar continuously	Minor water leakage, eventually escalates to bearing contamination and shutdown
Relieve pressure safely if vessel exceeds 10 bar	Overpressurization during excursion with risk of vessel rupture

Structured Reliability-Centered Maintenance

RCM ensures maintenance resources focus strictly where failure consequences matter, eliminating ineffective calendar-based PMs on random-failure equipment while protecting critical safety and operational barriers.

Verify all calculations and assumptions independently before making operational, equipment replacement, safety-critical, or regulatory compliance decisions.
