A fishbone diagram, as the name implies, is a representation of a fish skeleton. The underlying problem is represented by the fish's head (facing right), and the reasons are represented by the bones of the skeleton; the ribs branch off the back and represent main causes, while sub-branches represent root causes. The mechanism's purpose is to precisely pinpoint the source and consequence of any business or project issue. A fishbone diagram can aid in the identification of probable causes of an issue.
