This document discusses knowledge management in law firms. It defines lawyers as knowledge workers who bring both explicit knowledge from their education and tacit knowledge gained through experience. It then outlines four categories of knowledge in law firms: administrative, declarative, procedural, and analytical. The document proposes a knowledge management technology (KMT) stage model and applies it to how KMT can grow in law firms. It concludes by predicting six types of expert systems that could help law firms in the future, such as diagnostic, planning, and argument generating systems.
