INTRODUCTION

Manufacturing MIS
Manufacturing is one of the areas where information systems have made a major impact. A typical.manufacturing MIS is used to monitor the flow of materials and products throughout the organization. In a manufacturing process, raw materials or parts are transformed to finished products, and a manufacturing MIS is used at every stage. Some of the common subsystems in a manufacturing MIS include: design and engineering, production scheduling, inventory control, process control and quality control.
This process requires a very sophisticated system for inventory and process control. The supply of parts has to be planned carefully so it closely follows the assembly schedule. You can't have boxes of parts piling up around the plane since it would become very chaotic. And you don't want one missing part to hold up the entire assembly process either.

Inputs to the Manufacturing MIS
• Strategic plan or corporate policies.
• The TPS: o Order processing o Inventory data o Receiving and inspecting data o Personnel data o Production process
• External sources

...the component in the organization TQM we at the specific time. The information system is also important in term of business process reengineering (BPR), also known as business process to achieve dramatic improvements in performance (Hammer, 1990).
For example, information systems in the automation of manufacturing processes in forms of computer integrated manufacturing (CIM) and its related technologies such as computer aided design (CAD), computer aided manufacturing (CAM) and flexible manufacturing (FMI) is dramatically changing the nature of the process subsystem and significantly impacting on organizational strategies. Information systems are the backbone of this wave of automation. Information systems integrate the different components of automation to enhance the efficiency and effectiveness of the process subsystem.
