calculations: scripts and processes as KM assets

In It All Adds Up the notion of calculations as knowledge assets is presented as novel and unique process in KM:

"Specifically, MathSoft is promoting the idea of using its technology to facilitate what it calls calculation management—the practice of viewing engineering calculations as knowledge assets that should be managed and reused."

Aren't the folks at CIO magazine a bit late in their 'discovery'? Mathcad calculations put up on an Intranet for a use by a community of engineers are nothing more than scripts (or processes) for performing certain functions--to produce some sort of output(s) given the set of inputs. The open source movement has been doing this for how long? :)

Relatively speaking, for a corporate culture context where knowledge (in form of scripts/calculations here) is perhaps not easily shared by individuals due to fear of loosing some advantage, this could be considered a unique knowledge management practice.
