While working on reviewing an Agricultural Knowledge Management Portal I have come across an interesting paper, which discusses about a content-Incentive-Usability Framework for Corporate Portal Design from a Knowledge Management Perspective.
It discusses about three important components:
First, Specify the issues involved with the creation and integration of content for knowledge portals.
Second, highlight the importance of providing incentives for employees to share knowledge.
Third, examine how user acceptance of KM portals can be promoted, and how this knowledge can be used to desing better corporate portals.
If you are interested to learn more about this framework please find resources at http://www.irma-international.org/chapter/content-incentive-usability-framework-corporate/17867/
