Paul is currently testing the design of his process. He is piloting the process and implementing feedback to optimize his process before he implements it across the organization. Paul is:

Question

Options

• AWasting his time
• BUsing the Six Sigma approach
• CUsing the iterative design approach
• DUsing the Lean approach

• A
  3% (1)
• B
  7% (2)
• C
  80% (24)
• D
  10% (3)

Explanation

Option C is correct because Paul is piloting his process, gathering feedback, and refining it through repeated cycles of testing and improvement before full rollout - this is the definition of iterative design: build a version, test it, get feedback, improve it, repeat.

Why the distractors are wrong:

• A (Wasting time): Piloting before scaling is a best practice that reduces costly mistakes during full implementation.
• B (Six Sigma): Six Sigma focuses on reducing defects and process variation using statistical tools (DMAIC methodology) - not described here.
• D (Lean): Lean focuses on eliminating waste and maximizing value flow - also not what's being described.

Memory tip: Think of iterative design as the "spiral staircase" approach - you keep going around the same loop (test → feedback → improve) but each cycle brings you higher. Any time you see pilot → feedback → refine → repeat, that's iterative design.
