In many lines of business, goods are manufactured only as required to fill customers' orders. The order to manufacture should, in such cases, be an exact copy of the customer's order as entered. With the modern method of entering all orders in manifold──with a copy for each record required──one blank should be included for the factory, this becoming the production order. A form of this kind is shown in Fig. 40. This is an exact copy of the order as entered, the instructions in the heading taking the place of the name and address of the manufacturer. The particulars include the number, date received, and date to be shipped. The body of the order contains the necessary instructions; in the column at the extreme left──quantity ordered, quantity shipped, size, and description. This is one of a set of blanks that include the invoice, office copy, cost department copy, and copy for the shipping department. =24. Shop Orders.= The shop order is the written instruction of the superintendent to the foreman to do certain work or to manufacture certain articles. The order may call for the manufacture of a certain article complete, or it may be for parts to be later assembled into a complete article. Shop orders are as varied in form as production orders. [Illustration: Fig. 42. Shop Order Showing Total Work Cards] When a superintendent desires to start work on a stated production order, he lays out the work and issues the necessary shop orders to the foremen of the different departments in which the work is to be done. A shop order is issued for each shop──usually these are exact copies. If work on an order requires work to be done in four shops, the four copies are made on the typewriter, at one writing, by means of carbon paper. Fig. 41 shows a convenient form of shop order. This form includes the shop order number, piece number, drawing number, material, date to be completed, date of order, production order number on which the shop order applies, and the date completed. The body of the order is left blank for a description of the work and the necessary instructions. Explicit instructions must be given on every shop order──the order should leave nothing for granted. [Illustration: Fig. 43. Shop Order with Name of Shop] [Illustration: Fig. 44. Shop Order Showing Progress of the Work] The special feature of the shop order shown in Fig. 42 is the space for _card number_ and _total cards_. When an order is made out, as many copies are made as there are shops or departments through which the work must pass. The number of the copies of the order is entered under the heading _total cards_──that is, if the work is to pass through four shops, the figure 4 is entered in the space provided for total cards. The copies are numbered in the order in which the work will be done──that is, the order for the shop that does the first work is given No. 1, the second shop No. 2, etc.
