Which aspect does the fishbone chart in Root Cause Analysis typically identify?

The fishbone chart, also known as the Ishikawa diagram, is a tool used in Root Cause Analysis to systematically identify and visualize the various possible causes of a particular problem. This diagram is structured to resemble the骨 of a fish, showcasing the main problem at the "head" of the fish and the possible causes branching out from the spine. Each branch represents a category of potential causes, helping teams to brainstorm and categorize factors that might contribute to an issue.

Choosing the identification of possible causes as the focus of the fishbone chart captures its primary purpose effectively. It allows teams to explore different dimensions such as people, processes, materials, and environment that might be responsible for a problem, facilitating deeper insights and discussions.

In contrast, the final results of an investigation refer to conclusions drawn after analyzing the data, which is not what the fishbone chart specifically aids in. The specific actions taken after identifying an issue come into play later in the problem-solving process and are not within the scope of what the fishbone chart covers. The feasibility of various solutions is also explored at a later stage when solutions are being evaluated for implementation, rather than during the initial identification of causes. Thus, the correct focus of the fishbone chart is on uncovering and categor
