Ask HN: How do you collaborate on data-science?

After reading the Airbnb blog about their new Knowledge Repo [1] it seems that its difficult for data-science teams to work efficiently together; that there are issues with reproducibility and discoverability of others work.

I'm wondering what do you do in your company to solve this, or is it a problem for you?
