RAM Quality Assurance & Improvement 3

Question 1

In reliability-centered maintenance (RCM), what is the primary criterion for selecting a maintenance task?

Accepted Answer

Task must be technically feasible and worth doing

Answer

RCM requires that a maintenance task be both technically feasible (capable of detecting or preventing the failure) and worth doing (cost-effective relative to consequences).

Question 2

Which quality improvement tool maps the sequence of steps in a process to identify bottlenecks and non-value-added activities in a maintenance workflow?

Accepted Answer

Value stream map

Answer

Value stream mapping visualizes the flow of materials and information through a process, revealing waste and improvement opportunities.

Question 3

A process capability index (Cp) of 1.33 indicates that the process:

Accepted Answer

Is capable with some room for variation

Answer

A Cp of 1.33 means the process spread fits within the specification limits with a buffer, generally considered acceptable in many industries.

Question 4

In a RAM quality program, a 'preventive action' differs from a 'corrective action' in that it:

Accepted Answer

Addresses potential nonconformances before they occur

Answer

Preventive action proactively eliminates the cause of a potential nonconformance, whereas corrective action reacts to an actual nonconformance.

Question 5

Which failure analysis method uses a logic diagram to systematically evaluate combinations of events that could lead to a specific top-level undesired event?

Accepted Answer

Fault Tree Analysis (FTA)

Answer

Fault Tree Analysis uses Boolean logic gates to model combinations of lower-level failures that result in a defined top-level failure event.
