Root cause analysis (RCA) is a tool designed to help identify not only what and how an event occurred, but also why it happened. Only when investigators are able to determine why an event or failure occurred will they be able to specify workable corrective measures that prevent future events of the type observed. But, things aren’t always as simple as they appear. Sometimes, we must step back and take a look approach with fresh eyes.
