                                          CHAPTER SUMMARY

                                          The production process involves the various steps and activities necessary to
                                          manufacture or assemble fi nished goods and semifi nished goods. Organizations
                                          utilize different manufacturing strategies depending on the type of material
                                          being produced and the business model needed to sell those materials profi t-
                                          ably. The two most common production strategies are make-to-stock and make-
                                          to-order. In make-to-stock, the materials are produced and stored in inventory
                                          for sale at a later time. In make-to-order, production occurs only after the com-
                                          pany receives a sales order.
                                               The most common types of production processes are discrete, repetitive,
                                          and process manufacturing. In discrete and repetitive manufacturing, each unit
                                          produced is distinct from other units, and the component materials from which
                                          the unit is made can be identifi ed. In repetitive manufacturing, the same mate-
                                          rial is produced repeatedly over an extended period of time at a relatively con-
                                          stant rate. In discrete manufacturing, the company produces different materials
                                          over time in batches, often alternating between materials on the same produc-
                                          tion line.
                                               Process manufacturing refers to the production of materials in bulk vol-
                                          umes (liters, gallons, barrels, etc) rather than individual units. In process manu-
                                          facturing the component materials cannot be identifi ed because they are mixed
                                          together in the fi nal product.
                                               The production process consists of eight key steps: request production,
                                          authorize production, release production order, raw materials and semifi nished
                                          goods issue, production, production confi rmation, fi nished goods receipt, and
                                          production order completion. Each of these steps is affected by many variables
                                          inside and outside the production process and creates or updates many docu-
                                          ments throughout its execution.
                                               Key master data for the production process are contained in the bill of
                                          materials work centers, and product routings. The BOM identifi es the raw mate-
                                          rials or semifi nished goods needed to produce one or more units of a fi nished
                                          good. A BOM can have one level for simple goods or many levels of nested
                                          hierarchies for more complex goods. BOMs contain detailed information on the
                                          fi nished good as well as each of the component materials needed for production,
                                          warehouse management, and fulfi llment.
                                               The physical operations in the production process are carried out in work
                                          centers. Data regarding the type of work center, the operations performed there,
                                          and the relevant scheduling needs appear in the product routing. A product
                                          routing contains all of the operations or tasks needed to produce a material, as
                                          well as the sequence in which those operations must be completed. Component
