How have you used or intend on using this resource?

Fishbone diagrams are quite helpful to detect the root cause of a problem. I have been using fishbone diagrams with my team to improve production for a long time. We hold meetings and brainstorming sessions to detect potantial causes  which prevent us to improve the product quality.
