Conducting service observing in large ground-based observatories involves delivering standard products to the user, as well as installing the mechanisms to guarantee the proper execution of the observations and the verification of the resulting data. This article presents the Quality Control system of the Very Large Telescope. Levels of quality are defined, corresponding to increasingly fundamental levels of verification of the observation process performance. After a presentation of the QC levels and their implementation for the VLT, the paper discusses the usage of instrument models. Indeed several developments make it more practical today to efficiently use models in the entire observational process. On the one hand, the proposer can prepare observations exposure time estimators and data simulators. On the other hand the observatory can control the instrumental configuration, test data analysis procedures, and provide calibration solutions with the help of instrument models. The article closes with a report on the instrument modeling efforts for VLT and HST instruments.
