Do you consider the impact of cultural differences in your global business process, say marketing campaigns?

yes

There will be impact of local culture.you have to do marketing compaign according to their culture and intrests !!it will give more sucess !!

It seems that your question is aimed at cultural differences as in geography. In my humble experience, each of us is amazingly unique even if we each look the same and grew up in the same time period and geography. The proliferation of the internet, education, and access to the greatest minds in print have enabled each of us who can read and write to develope uniquely in our own ways. We have much more to choose from and in the choosing have become less defined as a homogenized group.

Culture is critical even within one country, let alone a global view! Step one how pinpoint can a multichannel "campaign" get about it's target. Then decoding verbal (language), visual and symbology by using story telling, mindmaps and picture sorts... Move to motivations,,, Then what do we sustain, alter and create in their minds through the campaign...

Every culture (geographic and demographic) represents a different market opportunity and by definition has a different target audience. So to respect the brand and give the product its best chance in the marketplace global marketing comes back to local marketing -- every time.

Don't have the budget, there's the rub. But the bottom line is if you want to enter the market you need to respect the audience or risk jeopardizing your products and more importantly brand.
