In repetitive make-to-stock production, finished or semi-finished products are manufactured over an extended period of time within mass production. For instance, you produce handlebars (semi-finished product) for bikes using repetitive manufacturing (REM) and store them in the anonymous inventory until they are used to assemble bikes (finished product).
In this case you want to collect and analyze costs periodically on the product level. You analyze costs by period rather than by lot, which means that you collect the costs over an extended period of time and analyze them in each period. To meet these requirements, the production accounting method product cost by period is used.
