Question

Options

• AMachine warm-up time
• BInspection of final product
• CWaiting for next batch
• DTransforming material into product

• B
  4% (1)
• C
  8% (2)
• D
  88% (22)

Explanation

Transforming material into product (D) is the only activity that directly converts inputs into something a customer values and is willing to pay for - it changes the form, fit, or function of the material in a meaningful way.

The distractors represent non-value-added (waste) activities: machine warm-up time (A) is necessary downtime but adds no transformation the customer cares about; inspection (B) catches defects but does not itself change the product - in lean thinking, it signals a process flaw; waiting for the next batch (C) is pure waste (inventory/waiting muda) where nothing is happening at all.

Memory tip: Ask the "customer test" - would a customer pay extra for this step? Only transformation passes; no customer pays a premium because you warmed up a machine or stared at their product.
