📋 Solution:

Ops Lift

1) Eliminate non-contenders by inspection.

  • Replenishment: 80 → 78 (down).
  • Returns Processing: 60 → 57 (down).
  • Packing: 95 → 100 (+5 on 95 ≈ ~5%).
    Only three merit math: Picking (120→139), Sortation (180→205), Loading (150→173).

2) Compute just the contenders (percent = change ÷ 2022 value).

  • Picking: +19 on 120 → 19/120 ≈ 0.158 ≈ 15.8% (~16%).
  • Loading: +23 on 150 → 23/150 ≈ 0.153 ≈ 15.3% (~15%).
  • Sortation: +25 on 180 → 25/180 ≈ 0.139 ≈ 13.9% (~14%).

Answer: Picking had the largest percentage improvement, at about 16%, narrowly ahead of Loading (~15%) and Sortation (~14%).
