Published, here, an example of a Knowledge Management role description.
This role, called the "Global Know-How Counsel", is effectively the Head of KM, or CKO, for the Legal function within Shell. It does not seem to be a Network Leader role, though it could be considered to be a Practice Owner role, given the accountability for content, and given that they are looking for a Lawyer with KM interests, rather than a KMer with a legal background.
Knowledge sharing is a top priority in Shell Legal. It directly underpins our aspiration to be the best corporate legal team in the world by ensuring that our advice reflects our own expertise and experience as well as the latest legal developments and best practice. The Global Know How Counsel will be working in the Legal Director’s Office, reporting into the Legal Director via the Legal Services Coordinator and heading up the Central Knowledge Management Team (which) supports Shell Legal in 48 countries.
