This is what every boss spends 80% of his time thinking about, even if she doesn’t admit it: How do we (the team) work closer together?
i.e. How do we work better together?
i.e. working “better” and working “closer” being the same thing, QED.
So if that sounds like your life, Congrats! You’re doing the right thing.
If it doesn’t, and you’re a boss, then you might need to delegate more. Just saying.
