This document discusses the options for standardizing or localizing user experiences across different markets. It outlines three approaches: the nation state model with separate experiences for each country, the global model with a centralized experience, and the federation model with a basic centralized structure customized locally. The document advocates for the federation model and emphasizes using user research to understand local needs and tailor experiences accordingly rather than taking a one-size-fits-all approach. Research methods like qualitative interviews, quantitative surveys, benchmarks, and cross-market analysis are recommended to improve customer experience through human-centered localization.
