Root Cause Analysis in Confluence with Mermaid Fishbone + 5 Whys
· 7 min read
A root cause analysis is only as good as the disagreement it survives. When the 'root cause' box on your postmortem template contains one sentence, the meeting spends an hour relitigating that sentence. A fishbone diagram and a 5 Whys chain move the argument onto a diagram: everyone sees which categories were considered, which branch was chosen, and exactly how the 'why' answers arrive at a root cause.
Confluence is where RCA already happens — in the Root Cause Analysis template, in postmortems, in retros. The missing piece is a diagram that holds the reasoning. This guide shows you two copy-paste Mermaid diagrams: an ishikawa fishbone that maps every candidate cause category, and a flowchart 5-Whys drilldown that lands on one concrete fix.
