I have worked at both Amazon and Google. The document writing culture is 10x more serious at Google. If you didn’t write a doc for a project, it didn’t happen.

However, the review process is different. People are expected to comment on the document beforehand and use the meeting to discuss any contentions. The google doc comments accurately capture the history of why a particular decision was made.

I found the Amazon wiki and quip terrible tools for writing docs. In practice, folks spent only the first five minutes reading a doc. That is rarely sufficient so you’re expected to read the document beforehand.
