The consensus seems to be that culture's influence dictates that learning must be approached at an 'organizational level,' not at the level of individuals, yet success for organizationally scoped learning initiatives has been fleeting. Given my deep investigation of knowledge itself, I think the perception of knowledge as an 'information resource' -versus- as a 'network of socially shared conceptual constructs,' is at the problem's root. Further, I think this lack of understanding is adversely 'infecting the metaphor of adoption' as opposed to 'enabling a value' of shared-learning which then can inform the organization's mission which then rather naturally constitutes the organization's resulting culture (culture is mostly influenced by actions, not sentiment). Though it my have presented problems in the past for many, in my experience, it's much more effective to pursue individual self-directed learning (especially if some hot-shot knowledge workers make some early visible wins!). [of course you should note that my professional practice is developing knowledge work practices and processes for individuals, so I'm quite biased!!!]
