I work at a very large company so you won&#x27;t be surprised to hear we use a variety of tools and there&#x27;s often overlap. Almost everything goes to Confluence (our program wiki) including tech specs and marketing documentation. The product team often uses something simple, such as Quip to store and collaborate on their docs. Marketing tends to migrate toward Drive. I think the best advice I can offer is to keep one &quot;source of truth&quot;. This isn&#x27;t too difficult when your team is small but as you start to grow, having one place devs, marketing, sales can go really helps streamline things.
