Abstract	During the High-Luminosity Large Hadron Collider upgrade, the current ATLAS Inner Detector will be replaced with the new Inner Tracker in order to cope with the increased track density, harsher radiation environment and higher data rates. The ITk is designed to be an all-silicon tracking detector with a strip detector surrounding the inner pixel detector. The strip tracker will consist of a central barrel detector with four layers (12,000 modules total), and two end-caps, consisting of six discs each (7,000 modules total). The 19,000 modules required for the full detector will be assembled over the course of a production phase planned to last 50-54 months. Before that, 5% of the module production volume was assembled in order to exercise the full assembly and quality control chain. This contribution presents an overview of the pre-production phase results and discusses issues encountered, which are critical for ensuring the success of the upcoming production phase
