A fishbone diagram commonly organizes root-cause categories into major groups including People, Processes, Equipment, and Environment.

• A. People, Processes, Equipment, Environment
• B. Data, Policy, Finance, Time
• C. Skills, Attitudes, Resources, Demand
• D. Laws, Regulations, Compliance, Audits

Answer: (A)

In root-cause analysis, a fishbone diagram helps a team see where problems originate by breaking contributing factors into broad, organized groups. The four major groups—People, Processes, Equipment, and Environment—cover the main domains where issues arise: human performance, how work is done, the tools or machines used, and the surrounding conditions. This structure keeps brainstorming focused across distinct areas and helps ensure nothing obvious is missed. Other options list factors that aren’t standard primary categories for this diagram; they may be important sub-factors but don’t form the typical major branches. So the arrangement of People, Processes, Equipment, and Environment best fits how a fishbone diagram is usually structured.
