Work orders are a key part of every operation that is performed on the shop-floor. A world-class manufacturing operation is built from a series of smaller, individual manufacturing operations. The intelligence, and therefore the effectiveness, of a Manufacturing Execution System (MES) or Manufacturing Operations Management (MOM) solution is directly proportional to the capability of the work order infrastructure. More specifically, we mean work orders that are internal to the manufacturing organization, not commercial contracts between suppliers and customers. The basic definition of the work order is quite simple; it can be thought of as a group of many units of the same product that will be manufactured together in the same way.
