My big takeaway from this is that it's NOT about asking people to compromise their personal values- that probably makes people feel attacked and undervalued.
Rather, it's about getting people to see that different situations require different skillsets- and teams are actually better off when they have diverse perspectives and values- if they can work together respectfully.
Another point I'd add (from a designer's perspective) to get different teams on the same page is that, cross-team collaboration and communication can often be made more effective and richer simply by using whiteboard and markers during discussions. Having something visual to point at and talk about makes it easier for everyone align themselves to each other’s lenses, and also reduce misunderstandings that drive people crazy.
A quote comes to mind: "A prototype is worth a thousand meetings." I think it's always easier to get on the same page if we're literally looking at the same thing (as opposed to arguing about our ideas about said thing.)
