Consulting firms and other knowledge-intensive organizations leverage a single asset: the collective learning and knowledge of their staff. They collect, retain and disseminate skills, best practices, and project histories as they market and deliver services to clients. In the past these activities were performed through a combination of written documents and formal and informal relationships among the staff over time. Electronic mail and, more recently, groupware tools have emerged to store and access these knowledge documents. Through these tools, firms may grow repositories of corporate experience and encourage new information sharing relationships (Orlikowski 1995).
