You have rightly mentioned that there is no “one size fits all” when considering global expansion of RSS. I completely agree that businesses will need to adapt to the local policies and social and cultural norms. The differences in economic, financial, social, cultural and political factors will pose several challenges for the success of RSS in different countries or regions.
Adding to your list of focus areas for businesses — differences in ICT infrastructures should also be considered not just to “keep the lights on” in the event of a disaster. Not all areas will have enough Internet access to support maps. This article gives an interesting example of how Uber had to create a simplified version of the “arrival time” screen that works better with 2G network is some developing countries as opposed to 4G cellular network in the US.
The article also explains other challenges that Uber faced in trying to design an app interface that made sense across many different cultures. Uber eliminated the signature “U” as it didn’t have much relevance in many countries. It was also interesting to read about how they overcame the obstacle of certain countries like India that don’t use proper addresses. Indians tend to use alternative ways to communicate their locations so Uber provided a way for riders to take photos of their locations and send them to the drivers to communicate their location. These customizations and many others are needed in ride sharing services to succeed in international markets. So as you’ve mentioned, its important for businesses to be flexible and adaptable.
