Maybe we could use publication impact of the work done as a measure instead, it would be as arbitrary as 'real work'?
I do not think that the publication impact is a good metric. A research/academic infrastructure used only, e.g., for testing and developing new programming models and/or technologies related to grid computing will surely have a large publication impact, as it will be used to try out new paradigms which will be subject to many publications. But not for this reason I would qualify such infrastructure as "production". I was trying to look for the definition of "production system" in some dictionary, but so far I failed to locate anything useful...
