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.
Just that lacking context one really can't make that many blanket statements.
I think the difficult cases come when people's interests aren't aligned. If you're coordinating with a vendor to basically detangle yourself from their vendor-specific tooling to be able to move away from them, at some level it doesn't really make sense to read them in on that.
There are degrees to this, and I think you can argue both sides here (so ultimately it's a question of what you want to do), but parties are rarely neutral. So the tough discussions come from ones where one party is going to be losing out on something.
IMHO the only correct way to measure the effectiveness of decision making is from the quality of executed outcomes. It is somewhat nonsensical to sever decisions from execution, and claim that decisions have been made rapidly if the decision doesn't lend itself to crisp execution. Without that, decisions are merely intentions.
To be clear this is Japan we’re talking about with the twenty years part. The same thing applies in the US but on smaller timescales though. If people feel appreciated and respected and you have good relationships, they will basically back whatever you want.
I tend to lean towards thinking backchanneling makes sense as a general vibe, if only because it's a way of doing things that lets people have dignity, and the costs _can be_ low.
How do you know what "the right thing" is at the outset without talking to the stakeholders?
I'm dealing with someone's "the right thing" that is actually wrong and dumb. They didn't ask us before rolling out the new "standard."
I think most people have at least one issue where they discount one of the stakeholder's judgement, it's all fairly contextual. But hey, if you're the CEO of some company you have the ability to act on that discounting.
