Question

Which of the following is most effective at finding system breakdowns to prevent problems from occurring down the road?

A) Root cause analysis
B) Process mapping
C) Trend analysis
D) Failure mode and effects analysis

Answer 1

Failure mode and effects analysis (FMEA) is the most effective method for preventing problems down the road by proactively identifying potential failure modes, causes, and effects in a system. Root cause analysis, while valuable, is typically used reactively after the problem has occurred.

Step-by-step explanation:

The most effective method for finding system breakdowns to prevent problems from occurring down the road is D) Failure mode and effects analysis (FMEA). While root cause analysis is crucial for understanding the underlying cause of a past problem, FMEA is a proactive approach that aims to identify potential failure modes in a system, their causes, and effects on system performance. It helps in prioritizing issues based on their severity, occurrence, and detection, thereby preventing problems before they occur. On the other hand, root cause analysis is commonly used after a problem has occurred to prevent its recurrence.

FMEA involves a systematic examination of components, assemblies, and subsystems to identify potential failure modes and their causes and effects. Teams can then implement strategies to reduce the likelihood of these failures or mitigate their impact. By contrast, root cause analysis is often a reactive process performed after a defect or issue has already manifested.
