Regardless of whether your project is mobile app localization, ERP localization, or game localization, your goal is most likely for your software to have increased popularity in a foreign locale. To measure your ROI from localization, analyze your software sales or subscriber base before localization and then analyze those same numbers in the period after releasing your localized software on the market. You are sure to find greater popularity and higher user adoption from a software that is effectively localized into the local languages.
