Which problem-solving tool is customarily used to complement the fishbone diagram?

• A. Brainstorming
• B. Regression analysis
• C. Control charts
• D. Gantt charts

Answer: (A)

The main idea is that a fishbone diagram visually organizes potential causes of a problem into categories, helping you see where issues may originate. Brainstorming is the tool that best complements this diagram because it generates a wide, unfiltered list of possible causes from a team. By encouraging free idea generation without immediate judgment, brainstorming provides the raw material you place on the fishbone’s branches. This collaborative generation helps ensure you consider diverse angles (people, methods, machines, materials, measurements, environment, etc.) before you start sorting and drilling down to root causes. After brainstorming, you typically refine and analyze the ideas (for example with 5 Whys or data analysis) to identify the true root causes. Other options—like regression analysis, control charts, or Gantt charts—serve different purposes (modeling relationships, monitoring variation, or scheduling) and don’t supply the broad set of potential causes that the fishbone diagram needs.
