It's interesting, after my time at Amazon (8 years) -- I struggled to visualize decisions without a document, because you get so used to reviewing things in that way. However, it's EXTREMELY heavy-handed. People will give you comments on the structure of your document (to "raise the bar") instead of the content of the document, and often you can't get documents reviewed until they are aesthetically in the right place for people to digest them. Ultimately, I think it makes sense when you're at a large organization with high attrition (such that you need to keep track of all of the decisions which are made), but otherwise, it's probably not worth it to do a formal document writing process.
I don’t think that is specific to Amazon. If anything I think the whole paradigm of “over analyzing communications with vacuous update suggestions that don’t matter” is probably the most consistent thread I’ve found in all of corporate America. I’ll never forget early in my career we had huddled around a coworkers computer with our entire team including senior manager writing an email to a VP and the senior manager was making punctuation and the most inane wording updates you can imagine. I once thought there is no way the absurdity of the cost to benefit of that situation would be topped, but how naive I was - turns out generally companies seemingly can’t avoid that kind of atmosphere.
Like, clearly plastics are bad. And yet, humans like the convenience, the utility.
