CIM is the integration of overall manufacturing enterprise through the utilized of integrated system & data communication mixed with new managerial philosophies which results in the development of personnel or organizational efficiencies.
From the definition described above, the ultimate goal of CIM is the integration of all of the enterprise operation & activities around a common data collection. In this context, society of manufacturing engineers (SME) introduces the CIM wheel that gives a clear cut picture of relationship among all of the parts of the enterprise. It illustrated three layered integration structure of an enterprise.
Outer layer constitutes of general management that includes marketing, finance, strategic planning, manufacturing management and human resource management. The middle layer consists of three process segments: manufacturing planning and control, product and process determination, and factory automation. These process segments signify all the activities in the design and manufacturing phase of a product life cycle taking the product from concept to assembly. The center of wheel shows the third layer that includes information resources management & common database.
