Knowledge sharing is a critical phase of the Knowledge Management life-cycle since it is an important precursor to the actual usage of knowledge. Knowledge initiatives to improve knowledge sharing requires an analysis of current knowledge sharing processes to identify bottlenecks that hinder knowledge sharing processes. Current knowledge auditing techniques for assessing knowledge sharing problems in organizations are insufficient in addressing the specific knowledge context of particular business functions. We propose a new technique the Knowledge Sharing Environment Model (KSEM), to model the knowledge sharing environment of specific business functions that helps in identifying the impact of bottlenecks in such environments.
