The tension is familiar to anyone who has run a brand across more than one country. Head office wants consistency. Markets want relevance. Both are right, and the usual resolution, which is head office issuing a proposition and markets quietly ignoring it, is worse than either.
The thing that resolves it is separating what travels from what does not.
The position travels. The proposition travels. The articulation should not, and insisting that it does is the error at the heart of most global brand programmes.
Take an idea like ease. As a position, it is portable. The specific expression of ease that works in the Netherlands will fail in Japan, not because the idea is wrong but because what constitutes ease, and what it is defined against, differs. In one market ease means fewer steps. In another it means never having to ask. Same position. Different evidence, different proof, different words.
So the job is to be far more specific about the idea and far less prescriptive about the language than most global guidelines are. Most do the opposite. They are vague about the strategy, which gives markets nothing to work with, and rigid about the copy, which gives markets nothing to do except comply badly.
A workable structure looks like this.
Fixed at the centre: the position, the proposition, the reasons to believe, and the things the brand will not say anywhere. That last one matters more than it sounds. A shared prohibition list creates more consistency than a shared phrase book, because it constrains without dictating.
Decided locally: the articulation, the proof points, the competitive frame. That third one surprises people. Your competitive set genuinely differs by market, and a proposition sharpened against the wrong rival will land flat no matter how faithfully it has been translated.
Negotiated: naming, claims and tone, because these run into legal and cultural constraints that the centre cannot anticipate and the market should not have to litigate alone.
Two practical warnings.
Translation is not localisation and buying more of the first will not produce the second. A translated proposition is the centre's idea in local words, which is exactly what markets resent and customers do not respond to.
And test the proposition in your hardest market before signing it off, not your easiest. Most global propositions are validated in the home market, where the brand already has equity and the idea is carried by familiarity rather than by its own strength. The market where you are unknown is the honest test.
