Which of these is a benefit of nesting?

• A. Decreasing waste
• B. Increased energy use
• C. Longer lead times
• D. Complex machining

Answer: (A)

Nesting aims to maximize material efficiency by arranging parts so as to minimize scrap. By packing shapes closer together and reducing gaps, you use less raw material, which lowers waste and material costs—so decreasing waste is the best benefit. The other options describe outcomes that aren’t benefits of nesting: it doesn’t inherently increase energy use, and it isn’t about longer lead times or creating more complex machining. In practice, you might also see smoother production flow or faster setups, but the primary advantage you’re aiming for is less waste.
