Language Quality Assurance

Q: How do you define quality in translation?

We define quality in translation as a combination of accuracy, consistency, cultural appropriateness, formatting integrity, and linguistic fluency across every deliverable.

Q: What quality assurance measures are built into the workflow?

Our workflows incorporate dual review, linguist rating and scorecards, automated QA checks, adherence to ISO and ASTM standards, and structured client feedback loops to continually safeguard quality.

Q: Can QA be customized per client or content type?

Yes. We create risk-based quality plans tailored to each client and content type, adjusting the level of human review, testing, and validation based on regulatory requirements, use case, and business impact.
