One of the more difficult aspects of developing knowledge management as a strategic tool is the inability to derive a valuation model that can be consistently applied across organizations. This paper examines traditional accounting conventions, as well as more recently developed activity based costing concepts and extends them as a valuation model for human capital as a component of knowledge management. A simple amortization scheme based on asset service life completes the throughput of information through the asset account process. The predictive power is derived, not from the absolute dollar value, but from the changes in valuation that occur over time.
