Abstract: Within a method for monitoring for a business a secondary characteristic of a supplier which supplies the business, there is first provided a reporting database resident within a computer. The reporting database has a minimum of one field coded for a secondary characteristic of a supplier which supplies a business. There is then entered into the reporting database within the minimum of one field coded for the secondary characteristic data directed towards the secondary characteristic. There is then generated from the data directed towards the secondary characteristic a report. Finally, there is then transmitted to the business which is supplied by the supplier the report. The method is particularly useful for monitoring and controlling sub-supplier secondary characteristics of a transportation vehicle manufacturing business.
