&gt; no one moving physical stuff around in a warehouse could [move large company&#x27;s revenue by 10%]<p>Sure they could. They&#x27;re the feet on the ground, so to say, and so they have the best insight into inefficiencies which are occurring on a day-to-day basis. You can bet it wasn&#x27;t a CEO who discovered UPS&#x27; &quot;only make right turns&quot; trick. Or Bezos who optimized Amazon&#x27;s warehouses.<p>A 10% reduction in costs is very realistic for these kinds of finds, and those reduction in costs are worth more than a 10% increase in revenue.
