Root Cause and the Causal Chain
What is Root Cause and the Causal Chain?
Causes come in three layers: the surface cause (the warehouse didn’t ship), the intermediate cause (the warehouse never received the full order), and the root cause (there is no mechanism for passing information between teams). Keep asking what happened, why it happened, and what mechanism lets it happen again — you are looking for a mechanism you can change, not for someone to blame. A usable cause has to be specific, observable, checkable, and actionable: “the staff aren’t committed” is a label; “the goal wasn’t clear”, “they lacked the authority”, “there was no confirmation step” are things you can actually change.
Root Cause and the Causal Chain: common mistakes and how to handle them
A causal chain has to explain every link in it: bonuses counted on revenue alone → sales chased orders → collections were ignored → margin fell. Learning from a success story works the same way — don’t copy the visible actions, work out the conditions under which those actions paid off, and the chain that made them pay.
What the Root Cause and the Causal Chain questions test
sorting a problem into surface, intermediate, and root causes; judging which cause is the changeable mechanism; spotting a sweeping attribution (attitude, character, a whole generation); filling in a missing link in a causal chain; working out which layer a proposed measure actually addresses.
