The sort of consensus building ultimately involves having to do stuff to make people's opinions feel taken care of, even if their concerns are outright wrong. And you end up having to make some awkward deals.
Like with all this "Japanese business culture" stuff though, I feel like it's pretty universal in some degrees or another everywhere. Who's out there just doing things without getting _any_ form of backchannel checking first? Who wants to be surprised at random announcements from people you're working with? Apart from Musk types.
But of course some people are very comfortable just ripping the band aid off and putting people in awkward spots, because "of course" they have the right opinion and plan already.
Why context matters in judging whether some practice is good or not.
