Good point. I agree the word "productivity" is bundled up with many meanings, and it could be a whole study in-itself to unpack it. Preliminarily, I'd say productivity is pragmatic towards-which one identifies oneself (a hunter hunts, a writer writes, etc).

I've been reading Being and Time recently, and Heidegger makes an interesting distinction between what is "ontic" (a writer writing, for example) and "ontological" (a writer investigating the state of being behind writing). In this context, productivity interestingly can be in both the following ideas:

Ontically, productivity writing a book. Ontologically, productivity is understanding of the way of being a writer comports oneself to be a writer.

I think both ideas are equally important. I'm not sure why I'm writing this; maybe to address the difficulty with pinning down a consensus of what productivity means. but happy saturday!
