Systems Engineering in Engineering and Manufacturing Development Phase


A methodical and disciplined approach for the specification, design, development, realization, technical management, operations, and retirement of a system.

Alternate Definition
(Note: This article is updated to reflect the interim DoDI 5000.02 Change 2 dated February 2, 2017 and the subsequent Defense Acquisition Guidebook (DAG) revision.
Engineering & Manufacturing Development (EMD) is the culmination of the efforts and results of the prior Material Solution Analysis and Technology Maturation and Risk Reduction (TMRR) phases. Entry into EMD is a significant milestone because it represents formal program initiation. The primary purpose of Systems Engineering in Engineering and Manufacturing Development phase (EMD) is the reduction of system-level risk. Key Systems Engineering activities include:
  • Continued requirements refinement and evolution
  • Final definition of various system architectures
  • Requirements allocation down to all subsystems
  • Finalization of Derived Technical Requirements
  • Determination of Configuration Items (CIs)
  • Development of CI functional specifications
  • Completion of the refinement of CI functional specs into product specifications
  • Integrated testing of prototypes and EDMs (e.g., Qualification Testing, Developmental, Testing, and Operational Assessment)
  • Establishment of an initial product baseline
    EMD Systems Engineering work also completes any remaining initial systems design activities not completely finished during the TMRR phase.
General Information

Inputs to Technology Phase typically include:


  • A completed, reviewed, and approved System Allocated Baseline
  • A Preliminary Design Review (PDR) Report


Other inputs to EMD are typically the refined Outputs from the TMRR phase. Some of these include:


  • System Performance Specification
  • Exit criteria for the EMD phase
  • Acquisition Program Baseline (APB)
  • An updated Systems Engineering Plan (SEP)
  • A Test & Evaluation Master Plan (TEMP)
  • An Information Support Plan (ISP)
  • Programmatic Environment, Safety, and Occupational Health Evaluation (PESHE)
  • Validated support, maintenance objectives, and requirements
  • A product support strategy
  • A Capabilities Development Document (CDD)
  • Inputs for the Program Protection Plan & Threat Assessment Plan
  • Cost & Manpower Estimate


Outputs the EMD Phase typically include:


  • An Initial Product Baseline
  • Test Reports (from Verification and Validation)
  • Risk Assessment
  • A TEMP appropriately updated for the next phase
  • A SEP appropriately updated for the next phase
  • Product Support Element Requirements
  • A Programmatic Environment, Safety, and Occupational Health Evaluation (PESHE)
  • An updated Technology Readiness Assessment (TRA)


Inputs to key documents such as:


  • Capability Production Document (CPD)
  • Information Support Plan (ISP)
  • Cost and Manpower Estimate
  • System Threat Assessment
