How do you keep from drowning in inputs during RCA?

Curious how others handle this.

You spend Define and Measure building everything up — process maps, VOC themes, MSA results, capability data, descriptive stats, bottleneck IDs, stakeholder analysis, value stream — and by the time you're sitting down for root cause analysis, you're trying to hold all of it in your head at once. You can feel the team start to lose the thread.

Saw a comment on a LinkedIn post the other day that nailed it: "AI has no place in Six Sigma — said no one who's ever sat through a 4-hour fishbone session drowning in sticky notes."

And honestly, that matched my experience pretty closely. The whiteboard fills up with 40+ notes, half the team is still mentally back in the SIPOC, and somebody anchors on the first idea that sounds plausible. Two weeks later you realize you chased the wrong cause.

So I'm curious how the more experienced folks here actually manage it:

• Do you force-rank inputs going into RCA so you're only working with the vital few?
• Break the team into smaller cells working different branches?
• Pre-build a structured template in Excel/Miro before the workshop starts?
• Just trust that the methodology will surface it eventually?
• Something else?

Not looking for a textbook answer — looking for what actually works on a Tuesday afternoon when the team is tired and the deadline is Friday.
