Production and Deployment (P&D) Phase Site problems The purpose of the Production and Deployment (P&D) phase is to achieve an operational capability that satisfies mission needs. Operational Test and Evaluation (OT&E) determines the effectiveness and suitability of the system. The Milestone Decision Authority (MDA) makes the decision in an Acquisition Decision Memo (ADM). Entry into this phase depends on the following criteria: • Acceptable performance in Developmental Test and Evaluation (DT&E) and Operational Assessment (OSD OT&E) oversight programs); • Mature software capability; • No significant manufacturing risks; • Manufacturing processes under control (if Milestone C is full-rate production); • An approved Initial Capabilities Document (ICD) (if Milestone C is program initiation); • An approved Capability Production Document (CPD); • A refined integrated architecture acceptable interoperability; • Acceptable operational supportability; and • Demonstration that the system is affordable throughout the life cycle, • Be fully funded and • Pass Milestone “C” When enough systems are delivered and other pre-defined criteria are met, an Initial Operating Capability (IOC) can be attained, allowing for some degree of operations. Full Operational Capability  (FOC) is achieved when the system is ready to operate as required.
