Today he is responding to the demands of Commerce One's Global 2000 customers and developing solutions that leverage the power of Web services to enable companies to better connect and optimize business processes within and between enterprises.

Hoffman will discuss how companies can leverage collaborative Web services to build faster, smarter and more agile businesses.
