There are many products and services that require local differentiation to increase their sales and successfully compete with their local competitors.
One example is that of the food outlet McDonalds. McDonalds has thousands of outlets around the world and it pays a lot of attention in maintaining standards that are consistent in all their outlets. But there is some local differentiation required for consumers in many nations to accept what they sell. For instance in India, McDonalds does not use beef in any of it products as beef is not consumed by Indians. Similarly, to cater to a majority of the population that is vegetarian, McDonalds has incorporated many vegetarian dishes in their menu but which have a taste that complements their standard dishes instead of diverging from the menu they maintain internationally. Similarly, pork is not used in stores of McDonalds that are located in regions with a large population of people that follow Islam.
There are many other services and goods providers that have to use similar strategies and use local differentiation to match the preferences of their target consumer group in different nations. A one size fits all strategy would not work, leaving them unable to compete with local competition if that was not done.
