I don’t know where I picked it up, probably from one of my former bosses (flinty old management consulting hands). I’ve been quoting it, in Spanish, at almost every KM course and presentation. It gets people’s attention, it gets repeated, it ignites debate about the nature of knowledge, about transmission, about innovation. Translated, it states that:
«Knowledge can not be created nor destroyed, it can only be cut and pasted.»
If you know the proper source, I’d be happy to attribute it.
