Digital Engineering Information Exchange

Working Group Purpose & Mission


The Digital Engineering Working Group supports the strategic objective of accelerating digital engineering adoption and the role of system engineers in this new paradigm.

In addition to the Chair and Co-Chair, the Working Group activities are managed by a team of skilled experts:

Treasurer: TBD

DE Guide Product Lead: Missy Wallace

DE Measurement Product Lead: Cheryl Jones

DE Primer Product Lead: Darryl Howell

DVM Product Lead: Ken Zhang

Taxonomy Product Owner: Joe Gregory

DoD OSD Liaison: Frank Salvatore

NDIA Liaison: Chris Schreiber

  • The WG activities and products span the systems engineering lifecycle as it relates to Digital Engineering information inputs and outputs of ISO 15288 and 15289 digital artifacts.
  • The WG will also addresses the exchange of digital artifacts between various technical disciplines involved in the systems engineering lifecycle.
  • The WG covers the presentation of digital engineering information to classes of technical and non-technical stakeholders across the complex global supply chain.
  • When appropriate, the WG will adopt previous and evolving knowledge from standards and other sources regarding the exchange of digital engineering information between multiple disciplines, and digital technologies throughout the systems’ lifecycle.
  • Close collaborations will include the TIMLM WG, MBSE Initiative, AD SE Transformation, AD Technical Information. The WG will also collaborate with the NDIA Modeling and Simulation Division and Systems Engineering Division. When considering changes or additions to standards, the WG will engage the INCOSE Standards Initiative.
  • The scope of DEIX includes “The what?” or the characterization of the content and relationships, involved in the exchange of digital artifacts. DEIX does not include “The how?” or the means and mechanisms for exchanging digital artifacts. The Tool Integration Model Lifecycle Management Working Group (TIMLM WG) defines the means and mechanisms for information exchange


The Digital Engineering Working Group supports the strategic objective of accelerating digital engineering adoption and the role of system engineers in this new paradigm.

The following goals support this mission:

  • Address stakeholders’ digital engineering needs as it relates to systems engineering lifecycle standards such as ISO/IEC/IEEE 15288, 15289, 15504-6, 12207, 26531 and 24748.
  • Develop Constructs for Assembling Digital Artifacts: A set of constructs and conventions that define how to select, compile, and analyze digital artifacts to produce digital engineering content for stakeholders.
  • Identify, Leverage and Influence Standards to Address Gaps in Digital Engineering Implementation: To use the understanding of existing and missing digital engineering related standards literature to evolve a consensus-based standards framework. To identify existing standards and conventions that apply to Digital Engineering, determine the needs for digital engineering related standards; and then, determine the gaps. Finally, in coordination with INCOSE Standards Initiative, liaise with foreign and domestic standards organizations to petition for changes or additions based on knowledge gained from Digital Engineering Working Group products.
  • Adopt a Common Lexicon: Define concepts, achieve community acceptance, and monitor adoption of the lexicon by the global supply chain as a means to describe digital engineering


The desired output for the Working Group is a set of digital engineering guides and definitions to advance the adoption and implementation of systems engineering development. The WG may specify any outcomes and products in the Technical Project Plan(s) (TPP). The WG can make these available to the INCOSE membership. TPP’s shall be developed, submitted and tracked as defined by the applicable Technical Operations procedure.

IW24: International Workshop Focus

DEIXWG General Meeting

Overview of DEIXWG as a working group, structure, and work planned for 2024-25

DE Standards Framework (DEIX SF) - Completed

ISO/IEC JTC 1 SC7 resolution for AHG 6 digital engineering. SC 7 agrees with our recommendation to disband this ad-hoc group, so in 2024 we can better concentrate our work product digital engineering guide, DVM and DE taxonomy for standard considerations in Q4 2024. These work products will be worked within the existing ISO/IEC JTC1 SC 7 WG 7 (system lifecycle) in 2024 (INCOSE POC/ SC 7 convener Floyd Fazi).

Thanks to Celia Tseng for her leadership.

DE Primer and DE Guide - Joint Session

Overview of the current DEIX Primer and Guide work in progress. Enlist working members of the group, define a candidate set of metrics for version 2, and establish a roadmap for publication.

DE Taxonomy

Generation of ideas regarding relationships between DE terminology (e.g. what is the relation between the Digital Thread and the Digital Engineering Ecosystem). Request feedback for preliminary taxonomy terms to date.

Completed Activities: Preliminary taxonomy of DE terminology, founded on the Basic Formal Ontology (BFO) and Common Core Ontologies (CCO). Preliminary ontological representation of some terms, not all.

Digital Viewpoint Model (DEIX DVM)

Enhance utility of the Digital Viewpoint Model (DVM) in building/generating digital view and viewpoints.

Completed Activities: Baselined DVM framework in SysML model and technical white paper.

Planned Activities

  • DEIX Standards meetings Thursdays.
  • DEIX DVM meetings Fridays.
  • DEIX Taxonomy meetings Tuesdays.
  • DEIX Working Group General Meeting to be scheduled quarterly.

Planned Work Products

DE Guide

TPP Approved. Publishing schedule to be confirmed.

DE Primer

Publishing schedule to be confirmed.

DE Taxonomy

Complete ontology of DE terminology. Possible modeling in multiple standard tools to support reuse (Cameo Concept Modeler, Protege, OML Rosetta).

Digital Viewpoint Model (DEIX DVM)

Concepts and prototypes on using the DVM framework to build a digital view generating tool.
