Root Cause Analysis (RCA)

Compliance & Risk

Also known as: RCA

Definition

A structured method for finding the underlying cause of a problem so it can be permanently fixed.

Explanation

RCA (using tools like the '5 Whys') digs past symptoms to the real cause, ensuring corrective actions actually prevent recurrence rather than patching effects. It is central to supplier quality and continuous improvement.

Example

RCA traces repeated late deliveries to a supplier's planning gap, fixed by a scheduling change.
