This chapter surveys several classes of technologies and indicates which kinds of knowledge flows are enabled and supported relatively better and worse by such technologies. We look first at common problems associated with the most prevalent and prominent KM technologies and then discuss interactions between such technologies and the knowledge life cycle. The discussion then turns to examine expert systems technology, which addresses knowledge directly. This is followed by a discussion of simulation technology, which enables the development of tacit knowledge through practice in virtual environments. The chapter concludes with five knowledge technology principles and includes exercises to stimulate critical thought, learning, and discussion.
