This is the picture of the fishbone template:
How is intended to use this diagram (the template documentation only provides general guidelines about the process but not about how to use the template), do you have some video where to see how it works?
Per picture, I would expect people go a write possible causes for each area? I don’t see how it could work collaboratively.
I would think better to ask people to provide sticky notes for each area, and then to try to find the biggest root cause per area, eliminating duplicated, etc.
Thanks for any help or advise,
