Abstract: A method of monitoring supply chain activity throughout supply chain sites includes extracting, at each site, supply-related data to be monitored. The data is in plural formats and translated to a common format. The data is uploaded to a data collection center (DCE). Upon request, a portion of the data is formatted dependent on rights granted. The DCS comprises a data collector where the uploaded data is stored, and a publisher for publishing data collector data. Each site maintains its supply-chain data, a DTE for transferring the data to the DCS, input means for allowing a data collector query, and a display for displaying published data responsive to a query. The inbound data is monitored at the DCS. If a problem condition is detected, such as a shortage/surplus, an alert is asserted, e.g. by highlighting an Alert indicator. Upon alert indicator selection, details of the problem condition are displayed.
