Order takers answer the phones, check that inventory is available, and then prepare “picking tickets” for the warehouse stock pickers. One order may consist of several lines, with a different medication or multiples of medications ordered on each line. Each order taker can prepare picking tickets at a rate of one line every three minutes. The telephones are normally answered from 6 am to 4 pm Pacific Time.
