{Excerpt} Staff profile pages are dynamic, adaptive electronic directories that store information about the knowledge, skills, experience, and interests of people. They area cornerstone of successful knowledge management and learning initiatives. A determinant of organizational performance is the ability to leverage expert knowledge. Much of that is tacit and therefore difficult to capture, codify, and make available through search engines and database technologies. And so, when looking we usually turn to people we know for quick, reliable information. (Chance conversations can help too.) However, in the globalized economy, personal networks are no longer sufficiently diverse to identify all the right persons, much as reliance on random connections is a thing of the past. Staff directories are no longer adequate to the task: learning organizations thrive on rich and fluid linkages and need expertise location capabilities to put people in contact with one another.
