He doesn&#x27;t specify exactly how cubbies are selected at the &quot;inbound&quot; stage, beyond saying it&#x27;s random. I assume it&#x27;s left up to the associate&#x27;s own whims and judgements? I imagine the &quot;no identical items in adjacent cubbies&quot; rule improves the potential for picking the same item in parallel while preventing too much concentration, improving availability from different locations. I wonder what other constraints they are given for this stage.
