The quality of translation is highly dependent on the end user, content type, and business goals.  Some technical documents would require very precise translations, including precise translations of terminologies. Global campaigns don’t require such precise translations. Rather, it needs to convey a strong emotion or needs to send out a strong message.

A quality translation would really depend on the content that needs a translation. Talking to your translation company would be a crucial step in order to obtain a quality translation.

•    Gather previous quality translations that you prefer – those that are in line with your expectations. Also, include some examples that you don’t approve. This would serve as your provider’s guide to visualizing your expectations better.
•    Encourage your translator to try to understand and adapt the working relationships.
•    Check that an in-country reviewer can understand the style guidelines of translation.
•    Provide appropriate guidelines. This allows both the translators and the reviewers to get a better understanding of your brand.
•    Give your LSP access to the staging server.
•    Supply your LSP with quality content as a source.
•    Allow the translators and all in-country reviewers to have enough time to finish the translation and evaluation.
•    Regularly communicate with the LSP’s project manager.
•    Create a harmonious long-term relationship with the translators. Established relationship makes them more familiar with your business and thus, a higher quality translation.
•    Have a person to answer your LSP’s questions.

As you can see, the quality of translation largely depends on what and how you communicate with your translation provider and your expectations. So make sure proper communication is established and your requirements are received and followed properly.
