What % of R&D budgets is spent on localizing/translating or internationalizing software products?
The answer to this question varies wildly between organizations so we cannot provide a typical answer. In general, however, for software developers, localization is not seen as an R&D budget item since it usually is seen as a marketing expense or a non-R&D engineering task. Internationalization, however, is often part of R&D, but the amount invested in internationalization cannot be generalized.
