The James Web Space Telescope (JWST) is a large, infrared-optimized space telescope. System-level verification of critical performance requirements will rely on integrated observatory models that predict optical response accurately enough to verify that the allocated top-level wavefront error of 150 nm root-mean-squared (rms) through to wavefront sensor focal plane is met. The assembled models themselves are complex and require the insight of technical experts working as a team across multiple disciplines and organizations. Furthermore, responses in several key disciplines are strongly cross-coupled. This paper describes the breadth of the systems engineering and modeling approach used on the JWST including technical performance metrics management. The scope of the systems-level modeling includes stowed dynamics, deployed dynamics, thermal, thermal distortion, straylight, optics and attitude control systems.
