The term "knowledge manager" usually reflects the mechanistic paradigm in which the learn/know/act cycle can be made automatic habit, removing all thought or requirement to cognize any unique or comprehensive outcomes of one's action. See manager, five ins and leader and administrator for more on how to avoid this assumption. See learn for a more supportable model with examples. The term:e-learning is likewise to be avoided.
So-called "knowledge management" was derided as nonsense by the journal Information Research in 2002: continuous improvement, total quality management, and about 20 other terms used in management literature were (correctly) determined to be non-operational. See process arts, ultra method and living ontology pattern for a more moderate position leading to practical outcomes like wiki best practices.
