ATLAS is currently preparing for the HL-LHC upgrade, with an all-silicon Inner Tracker (ITk) that will replace the current Inner Detector. The ITk will feature a pixel detector surrounded by a strip detector, with the strip system consisting of 4 barrel layers and 6 endcap disks. After completion of final design reviews in key areas, such as Sensors, Modules, Front-End electronics and ASICs, a large scale prototyping program has been completed in all areas successfully. An overview of the Strip System will be presented  highlighting the final design choices of sensors, module designs and ASICs. Results achieved during prototyping, and the current status of production and pre-production on various detector components will be summarized, highlighting the technical challenges (Cold Noise and HV breakdown) that currently delay the start of production.
