Your company is investigating the use of Reliability Centered Maintenance. A RCM program would encompass which of the following features?

Question

Options

• AI only
• BII and III only
• CI and IV only
• DI, II, III and IV
• IPreserve system function (provide an output).

• A
  3% (1)
• B
  6% (2)
• C
  3% (1)
• D
  77% (27)
• I
  11% (4)

Explanation

Option D is correct because Reliability Centered Maintenance is a comprehensive framework by design - it encompasses all four features: preserving system function, identifying failure modes, prioritizing failures by consequence, and selecting effective maintenance tasks. RCM's strength is precisely that it integrates all of these elements into a single systematic methodology rather than addressing them in isolation.

Options A, B, and C are wrong because they exclude one or more core pillars of RCM. A (I only) is far too narrow - preserving system function is the goal, but RCM requires a structured process to achieve it. B (II and III only) omits the foundational purpose (I) and the task-selection output (IV). C (I and IV only) skips the failure analysis steps that make task selection meaningful.

Memory tip: Think of RCM as a four-step loop - What does it do? How can it fail? What happens if it fails? What do we do about it? - which maps to functions → failure modes → consequence analysis → maintenance tasks. If any step is missing, it's not true RCM.
