Question

Options

• AThree
• BFive
• CSeven
• DNine

• A
  9% (5)
• B
  2% (1)
• C
  83% (45)
• D
  6% (3)

Explanation

Lean Principles, rooted in the Toyota Production System, defines seven specific categories of waste (known as "muda") - making option C correct. These are: Transportation, Inventory, Motion, Waiting, Overproduction, Over-processing, and Defects.

Options A (Three) and B (Five) are simply too low - there is no recognized Lean framework grouping waste into three or five categories. Option D (Nine) overshoots the classic count; while some modern extensions add an 8th waste (Non-utilized talent/skills), nine is not a standard figure in any widely accepted Lean framework.

Memory tip: Use the acronym TIMWOOD - Transportation, Inventory, Motion, Waiting, Overproduction, Over-processing, Defects - count the letters and you'll always land on 7.
