Today, the typical manufacturer has between 20 and 40 information systems in any given facility. Despite good intentions, these largely exist as “data islands” and, because of historical difficulty in integrating these islands, decisions are often based on only the most immediately relevant system, with scant regard for the overall business picture.
Enterprise resource planning (ERP) systems have long held out the promise of improving this situation, but the reality is that there is a significant difference between making a business decision and implementing it in real-time manufacturing operations. Also, while ERP systems are very good at ensuring business rules are followed, they typically work on data that is periodically consolidated, which, by definition, is not current.
