According to the "ERP in Manufacturing Benchmark Report" published by the Aberdeen Group, the companies that implemented ERP can be grouped under three different categories - laggards, Industry Average and Best In Class- based on their scores in 4 different criteria vis. Process (what business value has been gained from ERP), Organization (corporate focus / philosophy, level of collaboration among stakeholders), Knowledge (visibility across manufacturing and order fullfillment process) and Technology (scope of ERP implementation and use of technology)
Process: While laggards do not measure any business benefits from ERP, the best in class not only document and continually measure the business benefits, they also update / tighten the business benefits as they achieve one milestone.
Organization: While IT department owns and drives ERP in case of laggards, it is the business that owns the ERP implementation in case of BIC customers
Knowledge: Best in class implementations provide real time visibility to the manufacturing and order fulfillment process.
Technology: While laggards implement only a few of the available modules and use less than 50% of the functionality of these modules, the best in class implementation implement advanced modules like workflow technology , event management etc and utilize more than 70% of the functionality in the implemented modules. Moreover, the best in class implementation are quick to imbibe latest technologies including SOA and other integration technologies.
