The Commissioning of ATLAS Data Quality Infrastructure with First Collision Data

The ATLAS data quality software infrastructure provides tools for prompt investigation of and feedback on collected data and propagation of these results to analysis users. Both manual and automatic inputs are used in this system. In 2009 and 2010 we have gained significant experience with collision data operations and analysis; we have used this experience to improve the data quality system, particularly in areas of scaling and user interface. This talk desecribes the commissioning experience and subsequent improvements.
