Use of the ________ approach is the most classic arrangement when constructing a Fishbone Diagram.

Question

Options

• AChronological
• B6M
• C5M
• DAlphabetical

• A
  11% (4)
• B
  80% (28)
• C
  3% (1)
• D
  6% (2)

Explanation

Option B (6M) is correct because the 6M framework - Machine, Method, Material, Man (Manpower), Measurement, and Mother Nature (Environment) - is the standard, widely-recognized structure for organizing causes in a Fishbone (Ishikawa) Diagram, making it the "classic" arrangement taught in quality management and Six Sigma curricula.

Option C (5M) is a common distractor because a 5M variant does exist (typically omitting "Mother Nature" or "Measurement"), but it is not the definitive classic form - the full 6M is the canonical standard.

Options A (Chronological) and D (Alphabetical) are wrong because Fishbone Diagrams organize causes by category, not by time sequence or letter order; using either of those would defeat the diagram's purpose of grouping root causes into logical themes.

Memory tip: Think "6Ms = 6 bones on the fish" - the diagram has multiple major branches (bones), and 6M gives you exactly six major cause categories to hang on those branches. If you remember that Ishikawa diagrams are used heavily in manufacturing quality control, the Ms (Machine, Material, Man, Method, Measurement, Mother Nature) all fit naturally into that industrial context.
