This document discusses how Gas Natural Fenosa's corporate university has transitioned from an e-learning model to an e-knowledge model based on Web 2.0 technologies and user-generated content. The corporate university previously provided 800,000 training hours to 54,000 participants annually through centrally-developed courses, but will now leverage new formats like video, wikis and blogs created by internal experts and other users. This e-knowledge approach allows for dynamic, decentralized knowledge sharing across the company and saves some costs while providing enormous added value through increased collaboration and information exchange.
