EMD Acquisition System

The Engineering & Manufacturing Development (EMD) Phase is where a system is developed and designed before going into production. The EMD Phases starts after a successful Milestone B which is considered the formal start of any program.  The goal of this phase is to complete the development of a system or increment of capability, complete full system integration, develop affordable and executable manufacturing processes, complete system fabrication, and test and evaluate the system before proceeding into the Production and Deployment (PD) Phase.

The purpose of the EMD Phase is to: (See MiIlestone Activity Map)

  • Develop a system or increment of capability,
  • Design-in critical supportability aspects to ensure materiel availability with particular attention to reducing the logistics footprint,
  • Integrate hardware, software, and human systems,
  • Design for producibility,
  • Ensure affordability and protection of critical program information,
  • Demonstrate system integration, interoperability, supportability, safety, and utility, and
  • Ensure operational supportability with particular attention to minimizing the logistics footprint
  • Demonstrate Reliability, Availability, Maintainability, and sustainment features are included in the design of a system

In the EMD phase the system architecture and system elements down to the configuration item (hardware and software) level are defined based upon the technology selected and integrated during the Materiel Solution Analysis (MSA) and the Technology Maturation & Risk Reduction (TD) Phase.  During this phase the system design requirements are allocated to the major subsystem level and are refined as a result of developmental and operational tests.  The support concept and strategy are also refined with detailed design-to requirements determined for the product support package elements.

The EMD phase consists of two major efforts: (1) Integrated System Design and System Capability and (2) Manufacturing Process Demonstration. These two major efforts integrated the end item components and subsystems into a fully operational and supportable system. They also complete the detailed design to meet performance requirements with a producible and sustainable design and reduce system level risk. EMD typically includes the demonstration of production prototype articles or Engineering Development Models (EDM).

Below are the major reviews conducted during the EMD Phase:


  • DoD Instruction 5000.02 describes the activities conducted during and information resulting from the Engineering and Manufacturing Development (EMD) Phase.  The tables in Enclosure 4 of DoD Instruction 5000.02 list the information requirements required by the Defense Acquisition Management System during this phase.
