Quality management
There are still discussions on what should be considered a high-quality translation. Is it an error-free document in the target language or the smooth process where every step complies with the established procedure?
Many linguists agree that it is when the translated document meets or exceeds the expectations of the client and the target audience. Although, it is very difficult to measure linguistic quality, everyone keeps talking about it, especially when they regard it as "poor".
And that's the point: quality can be both a subjective and objective notion. What Project Managers can do is to focus on the former aspect. One of the reasons for buying the TMS is improving the quality of translations and quality of the whole process.
