I am a fan of linear, critical, singular lists of 5 whys. I am not a fan of the matrix of whys that some companies have decided to begin implementing because of 1 blog post high up on Google searches that suggests to use matrices to organize multiple root causes. They don’t need to be combined. I would rather see multiple RCAs each with a singular concrete cause, than a single RCA with a 5x5 matrix of intermingling causes. It makes it harder to address and dig through each issue accurately in context - you’re always reconciling the causes against each other to form a cohesive story, when there’s actually a good chance that there were separate, unrelated causes to your incident.
