Having done my doctoral work on K sharing, I love this article for its comprehensive framework on KM. You make lot of sense in your explanation. However, I tend to disagree on your comment: "Too often, Big KM is seen as sufficient, but in complex work environments, Little KM and Personal KM are also needed and should work in conjunction with Big KM." Not just in complex work environment, but in modern day knowledge driven economy where yesterday's technology is archaic today, tools like SNA/ONA ( Social / Organizational Network Analysis) are so vital to team success which translates to organizational success.
