Which diagram is used to identify root causes of a problem?

The Ishikawa or Fishbone Diagram is specifically designed to identify root causes of a problem. This visual tool organizes potential causes into categories, helping teams to brainstorm and systematically analyze various factors that may contribute to an issue. The fishbone shape allows users to categorize causes under broader categories, which can include people, processes, equipment, materials, environment, and management. This comprehensive approach facilitates deeper exploration and understanding of the underlying issues, enabling better decision-making and problem-solving.

The Gantt Chart, while a useful project management tool for scheduling tasks over time, does not focus on root cause analysis. Similarly, a flowchart is effective for mapping out processes or workflows but does not delve into the causative relationships that lead to problems. SWOT Analysis helps assess strengths, weaknesses, opportunities, and threats related to a project or business strategy, but it does not specifically identify root causes of issues, making the Fishbone Diagram the most appropriate choice for this purpose.
