I participated in a KM / Enterprise 2.0 session with Royal Dutch Shell via APQC in which they shared a lot of great things about what they are doing in this arena. I found this article that captures very well what we covered in the session. I like that their focus is on the people and keeping the technology involved as simple and transparent as possible. I really believe that is a BIG key for successful adoption of these things. It’s got to be beneficial and easy to use — otherwise, why bother.
