An Engineering Development Model (EDM) is a system acquired during the Engineering and Manufacturing Development (EMD) Phase that is built from approved Critical Design Review (CDR) drawings. It may be used for development and operational testing to demonstrate maturing performance during the latter stages of development and to finalize proposed production specifications and drawings. Initial Operational Test and Evaluation (IOT&E) required by statute or regulation for Acquisition Category (ACAT) I and II programs to support a Full-Rate Production Decision Review (FRPDR) is normally performed on Low-Rate Initial Production (LRIP) articles during the LRIP effort of the Production and Deployment (P&D) phase. For other systems, or systems that do not have an LRIP, for which Milestone C is the FRPDR, production representative EDMs may be used as test articles.
