Fast and efficient methods for the calibration and the alignment of the detector are a key asset to exploit the physics potential of the Compact Muon Solenoid (CMS) detector and to ensure timely ?preparation of results for conferences and publications. The ?presentation will review the online and offline workflows designed ?to align and calibrate the CMS detector in Run-2 (2015-2018) and ?its impact on CMS detector performance and offline data processing for physics analysis.? The development in terms of alignment, calibration services planned during the Long Shutdown in 2019-2020 ?will also be discussed.
