A root cause is the beginning or initiating cause of either a condition or a chain that leads to an outcome or effect.  The root cause analysis is often referred to as a weed, if we don’t get to the root and remove the root, the weed will grow back again.  A root cause analysis digs below the surface or the effect in order to discover the initial cause of the effect.  Often times a root cause analysis will travel through levels of causation as it digs towards the root cause. ​
