Some people think of organizational alignment as "getting people to buy in" with an idea that is already formed. This may be useful sometimes but I don't think it's optimal.
Alignment is the process of synthesizing varied opinions and viewpoints on a subject.
Getting alignment on "why we're doing this is not about getting everyone to see "the right answer" so much as incorporating everyone's viewpoint into a "shared vision" of what that means.
Cultural alignment can mean "same thing" as in, "we are all driving toward the same goals" (true north) or it can mean "same way" as in, "we do things consistently."
A flock of geese does both -- can a modern organization work in the same way without stifling creativity?
