Today I gave a presentation on new business models for service oriented enterprise systems at the ARIS ProcessDays Nordic 2008. The presentation discussed how ERP functionality can be provided through services. New roles will emerge, like the platform provider who will provide support for a network of users and vendors. The audience showed much interest and posed questions about the consequences for ICT departments, whether security will be a problem for the new business models, the impact of open source, and the role of networks.
