Here's what wikipedia thinks of them today:
Creativity - "a mental and social process involving the discovery of new ideas or concepts, or new associations of the creative mind between existing ideas or concepts."
Productivity - "a measure of output from a production process, per unit of input."
However, I think of them in this way; creativity is the act of producing a new (or you could call it different) idea, and productivity is the act of creating a new material object (software, hardware, etc). I see creativity as essential in defining our humanity and productivity as the physical manifestation of our ideas, perhaps less essential as we move into the future. Colloquially, I believe productivity to be too attached to industrialization and societies of consumption, and I see creativity as being too attached to the arts. It seems that, for whatever reason, western cultures have placed an enormous division between the arts and sciences.
A change is overdue and I don't believe it will be found in the literature of establishments. Like many of humanity's more positive social changes, I'm betting it will come from the people.
