Which diagram is also known as the Ishikawa diagram and is used to identify major categories of causes such as Methods, Machines, Materials, and Manpower?

• A. Fishbone Diagram
• B. Pareto Diagram
• C. Histogram
• D. Flow Chart

Answer: (A)

A structured root-cause analysis tool that visually maps potential causes into major categories to facilitate systematic brainstorming. This diagram, known as the Ishikawa diagram, is shaped like a fishbone and organizes potential causes under headings such as Methods, Machines, Materials, and Manpower, helping teams identify where issues originate. It shines for uncovering multiple contributing factors across areas, guiding deeper investigation into root causes rather than merely describing distributions or the sequence of steps in a process. Other diagrams serve different purposes: a Pareto diagram ranks causes by frequency or impact; a histogram shows the distribution of a variable; a flow chart maps steps in a process. The fishbone diagram matches the described use.
