There are many people who really don't like the term Knowledge Management, and would much rather use some other terminology.
They start to use terms like "Knowledge Sharing" instead. "Knowledge Management" becomes a taboo term - something to be avoided.
You won't be surprised to learn that I am completely unapologetic about the term. I don't think it is an oxymoron, because I don't think "Knowledge Management" means "Managing Knowledge" (see here). For me, "Management" means "creating and maintaining organisational structures, frameworks, systems and processes to optimise the value of some area of focus". Then "Knowledge" represents the focus of this particular management system.
"Knowledge Management" is therefore "Management with a focus on Knowledge".
There is no need to apologise for this! This is what we should be doing! We should manage ourselves, our teams, our organisations, with a focus on knowledge.
What's the alternative? Management without considering knowledge? Knowledge-less management? Ignorant management?
Personally I don't like the term "knowledge sharing" as an alternative to "knowledge management", because it addresses only one element of KM, and ignores Knowledge Creation, Knowledge Synthesis, Knowledge Seeking and Knowledge re-use (see here for more details). But beyond this, I really don't think we need to be apologetic about the M word.
Management is what we do to make organisations work; to make them prosper and succeed. And if we don't manage with knowledge in mind, then they won't prosper and succeed to the same extent.
So don't apologise, don't be shy, stand up for the M word. Divorcing "management" from "knowledge"also means divorcing "knowledge" from "management". If you are talking to managers, then they need to understand that these two cannot and should not be divorced. They cannot manage properly, if they ignore knowledge.
And if we manage with due attention to the value and importance of knowledge, then this is Knowledge Management, and this is what we should be doing.
