Importance of client feedback
When you’re doing a large project with a LSP that requires multiple linguists and your company specific terminology, the importance of providing feedback for the first few batches of files can not be over emphasized. In this scenario you should not expect total quality until at least 2 to 4 batches of files have been completed, feedback has been provided, and the linguists have had the opportunity to integrate the feedback into the current and future batches. Moreover, if you maintain your own terminology database, there might be technical issues that have to be addressed before total quality can be realized. For example, is your terminology database based on industry standards? If not then there might be a great deal of technical challenges to get thru (32 bit vs 64 bit or OS incompatibilities.)
While it is reasonable to accept total quality for the entire project, it can not be realized without giving enough time to implement your specific feedback. It is best to work with your LSP contact to ensure your feedback has been successfully integrated into the project.
