European Space Astronomy Centre, Madrid, Spain An analysis system used for scientific data reduction of a living instru-ment needs permanent evolution. The calibration of working detectors never ends. A better understanding of the systems involved, their even-tual degradation, as well as new challenges reflected eventually in differ-ent observational modes lead normally to the necessity of extending the analysis capabilities of the software used as well as to an update of the calibration data used for derivation of final scientific products. Of course this leads immediately to the necessity of making those updates public as fast as possible, as well as making the whole analysis system publicly avail-able. On the other hand, standard high level products, derived under a fixed software / calibration configuration, optimise the generic approach to ex-ploiting the scientific contents of the observations. The SAS is our answer to these requirements. It serves both as the Interactive Analysis system, freely distributed by ESA's XMM-Newton SOC, located at the European Space Astronomy Centre (ESAC) near Madrid, Spain, and, through a subset of its functionality, it sup-ports the data processing pipeline, used centrally in the Science Survey Centre (SSC, University of Leicester, UK) for derivation of final products. The pipeline products are distributed to the observers through the cent-ral scientific archive (XSA) maintained at the SOC. The SAS is contributing in a decisive manner to the high rate (250-300 / year) of scientific refereed publications based on XMM-Newton data. Furthermore, a substantially upgraded new SAS version is sup-porting the ongoing general reprocessing of all of the XMM-Newton data gathered so far. Finishing before the summer of 2006, it will re-populate the XMM-Newton archive with a set of high-level homogeneously calib-rated scientific products. It will also generate the largest catalogue of hard X-ray sources ever compiled . We intend to review the main aspects of the SAS, which we consider essential for the scientific success of the XMM-Newton mission, as well as the strategies to further extend its capabilities and to adapt to the different stages of the mission. It will also generate the largest catalogue of hard X-ray sources ever compiled (~2-300000 entries, mostly previously unknown sources).
