Real world supply chains differ not only in their current standard of performance, but also in the most effective actions required to move each towards world class supply. A generic approach for the identification of the appropriate re-engineering programmes based on the uncertainty circle principle is presented. A total of 20 European automotive supply chains have been analysed via a quick scan audit procedure. The output is a clear portrayal of the present health status of those supply chains. Some 10 per cent of these are performing at the present day level of best practice, with a further 20 per cent within sight of this goal. Specific re-engineering requirements are identified for the remaining 70 per cent dependent on present maturity levels.
