"Multilingual" is not a sufficient requirement. Define language, volume, channel, hours, proficiency level and customer geography.
Models include dedicated native-language teams, bilingual agents, shared multilingual pools, translation-assisted digital support and AI language support. Evaluate spoken and written fluency, accent comprehensibility, cultural context and industry vocabulary.
Forecast volume separately by language and ensure QA reviewers can evaluate the language they score. Geography can materially influence the available talent pool.
