The management of knowledge has become a major research field in different disciplines in the last years. A key issue is the future development of knowledge management as a “fashion” or “trend” initiative. A longitudinal empirical study conducted by the authors analyzing the literature of knowledge management from 1994 until 2004 comes to the conclusion that knowledge management is already transformed into a “trend”. Furthermore, this chapter deals with the integration of knowledge management in the banking sector by applying the building block approach from Probst, Raub & Romhardt. Currently knowledge management is used in an unbalanced manner and not considering all knowledge-intensive processes.
