Companies are showing relatively little interest in renewing their ERP systems, even when existing software no longer meets current requirements, according to a new study.

In a poll conducted for consultants Planat, 79 pc of executives cited high investment costs as the biggest obstacle. A third said they didn't need new business process management software.

But Planat Managing Director Christian Biebl believes change will come anyway. Production software and ERP will come together and many companies will need upgrades to existing systems to handle this change, he predicted.

"The main challenge for companies will be to determine precisely what options already exist internally and how they can be enhanced,"  Biebl said.

Despite their reluctance to invest, German IT managers and business executives are expecting ever more from their ERP systems, according to the poll, with 61 pc seeing a need to improve the adaptability of their software.
