The object of the present invention is to ensure information sharing in a factory and enhance the production efficiency. The management system of the present invention utilizes a liquid crystal projector PRJ to project an image of management information on a large-scaled display in the factory. A screen SCR is located at a specific position that allows each worker to simultaneously recognize the display and the object of the display (for example, in the case of a storehouse, the storage status of products). The contents of the display are varied according to the location of the display: for example, (1) instructions and actual conditions of storage of products in the storehouse; and (2) requirement of parts from assembly lines to a parts warehouse and status of delivery of parts from the parts warehouse. In a staff room of managers, information with regard to a first process, which is upstream most in the work flow in the factory (status of carrying-in work of parts and materials from outside) and information with regard to a last process, which is downstream most in the work flow (status of shipment) are displayed simultaneously. Such display enables workers in various sections and managers to accurately grasp the working status in the factory in real time, thus attaining the smooth operations and enhancing the production efficiency.
