Counting

Counted, and waiting for somebody else

A count that differs from the book by more than the tolerance does not move the book on its own — db/231. Somebody who did NOT take the count has to accept it. That is not a formality: a count and its approval by one person is the same as no approval at all.

What to count next

Locations classed by how much they move, because movement is what creates error: a shelf touched forty times a week drifts and one touched twice a year does not. Never counted comes first — a shelf holding stock that nobody has ever verified outranks anything an interval can say about a shelf somebody has.

What has been counted

The last thirty days, including the counts that found nothing wrong — which is the whole point of db/108 and did not exist before it. A count marked agreed moved no goods and is still evidence: it is the only thing that can say a shelf is right. A count that disagreed by more than the tolerance says so under the name — it has not moved the book and is waiting for somebody else. db/231.

Which shelves the book keeps getting wrong

Occasions, of how many, and the swing rather than the net: a shelf that went +30 then −30 nets to nothing and has been wrong twice. The residue is what makes a badly-labelled aisle look fine.
