What is a root cause vs a contributing factor?

• A. Root cause is the underlying fundamental reason for the incident; contributing factors are secondary issues that worsen it and can be multiple.
• B. Root cause is always the same as the incident outcome.
• C. Contributing factors are the primary cause, while root cause is minor.
• D. They are interchangeable terms.

Answer: (A)

In incident investigation, the root cause is the underlying fundamental reason the incident happened, often tied to a gap in the safety management system, such as deficient training, flawed procedures, or weak supervision. Contributing factors are the secondary conditions that exist around the incident and can worsen it or make it more likely to occur, and there can be multiple of them. The root cause is what, if addressed, would prevent recurrence, while contributing factors are conditions that facilitate the incident but aren’t the primary reason. For example, if a machine fails because maintenance scheduling was inadequate, the root cause is the maintenance scheduling deficiency. Contributing factors could include an operator not performing a daily check, a worn part that wasn’t flagged, or production pressure that led to bypassing some procedures. This distinction is why the correct statement best captures the relationship: the root cause is the fundamental reason, and contributing factors are secondary issues that contribute to the incident. Other options blur or reverse these relationships by saying the root cause equals the incident outcome, or that contributing factors are the primary cause, or that the terms are interchangeable.
