Users are only running 50% of the functionality implemented in their ERP system, and are paying for functions they never use, according to the just published Butler Group report, 'Exploiting Enterprise Applications' which examined sixty large businesses. According to the report a significant proportion of the unused functions had been specifically coded for the businesses concerned. “ERP is complex and getting end users in the business to use it is still a big challenge,” said report author Teresa Jones. She urged IT directors to audit which parts of the system were being used every s, and to identify any additional end-user training that might be required to ensure the system's full functionality was used. The Butler study echoes AMR Research finding from last year which found that 46% of ERP licences were unused, leaving many users with unnecessary support and maintenance bills.
