The paper presents results of a pilot programme aimed at efficiency improvement in a multisite factories system for automotive component production. Firstly, the company background has been outlined and main problems of the old manufacturing system have been examined. In order to increase competitiveness in global and turbulent markets a renewed organization approach has been proposed based on total manufacturing management and just-in-time methodologies. Improvements in set-up and lead times, work in progress, material handling, product and process quality, environmental effects, have all been assessed, keeping a quite low project cost (around $4 million).
