Knowledge management in law firms has evolved through three phases  . Phase one focused primarily on the development of taxonomies to systematize attorney work product and related research. The second phase focused on enterprise search to mine the growing volume of information managed by law firms. Legal industry specific search engines such as Recomimind were deployed by many AmLaw 100 law firms during this phase. Phase 3 was driven by changes in the legal market place and growing competition that led to price pressure and increased demands for efficiency from clients. A major focus of law firm KM today is in using historical billing information to generate alternative fee arrangements and more generally in the area of legal project management to more efficiently deliver legal services to clients.
