Measuring the value of knowledge is rapidly becoming a topic of interest in
the wake of the increasing attention for knowledge management. Several app
roaches have been proposed in the past, most of them focused on measuring a
t a high level of abstraction the "intellectual capital" of a company. A lo
w-level approach, meant to measure the value of separate knowledge assets i
s defined in a formal model. The model calculates the return on a knowledge
asset (its value) as the difference between the cost incurred for using th
e knowledge asset in activities to produce products minus the revenues gene
rated by these products. The activity side of this equation relies on Activ
ity Based Costing. For the revenues side different procedures can be used f
or distributing product revenues over activities and knowledge assets. The
approach is illustrated by a case study concerning loan revision performed
in a large bank in Netherlands. It was shown that the method is applicable
and led in the case study to the unexpected result that the return on most
knowledge assets for loan revision was negative. The results of the method
could also be used to calculate the financial prospects of re-engineering p
roposals. To conclude, several constraints and benefits of the method are d
iscussed. (C) 2000 Elsevier Science Ltd. All rights reserved.
