Interesting material to use for analyzing the value of a WCMS. Might use it myself for comparing the candidates.
The Analytical Hierarchy Process (AHP) is a set of principles or a framework for evaluating investments. To soften the subjectiveness of the framework, a wide range of sensitivity analyses are performed.
A framework is presented, a bit similar to the one in Management Challenges of the New Infrastructure, only less complex (Input -> Process -Output).
The framework is mostly applicable for doing pair-comparisons, so the candiates should be reduced to a handful before doing the benchmark.
Funny how this article regards WCMS to be what most thinkers consider to be ECM..
Overall, this article uses alot of text to get to the point, but the framework presented is quite good, and I will probably use it.
