The best thing a product marketing team can do for a sales team is give them ONE PLACE TO LOOK & SEARCH for the things they need. When you have a single source of truth, things become so much easier, and it’s easier to fill in the gaps.

Bonus thought: Ideally, each page would have a comment section so you can gauge the vailidity and helpfulness of each document. This is why good wiki software is such a good solution, but it has to be adopted across the WHOLE team.

I’ve led a few crosss-company projects to consolidate knowledge into one wiki, and its not easy; but the reward is there if you stick with it.
