Digital Engineering Information Exchange Working Group (DEIX WG)

For introduction to the DEIXWG, please visit our INCOSE page to view our WG Scope and Goals.

Within INCOSE, this DEIX WG supports the strategic objective to accelerate the Transformation of Systems Engineering to a model based discipline. The DEIX WG aspires to ensure Digital Artifact are transferable within industries with complex systems. For example, the aerospace & defense, oil & gas, transportation, automotive, healthcare, and utility industries. The successful fulfillment of this mission allows for the free flow of digital artifacts between buyers and suppliers throughout a global supply chain; as well as, enable the collaboration between disciplines within those industries. Despite advances in the digital era, there are significant inefficiencies in cost, schedule, and performance when suppliers and acquirers exchange information following a traditional document-based approach. A solution is to leverage advances in digital technology to provide enriched, interactive system representations that deliver data, information, and knowledge to stakeholders.


The purpose of this website it provide an expanding community of interest with the evolving thought leadership on digital artifacts and their exchanges. We strongly encourage feedback & questions, innovative ideas, and knowledge brokering within the community. Please feel free to email the coordinators of the working group and we will address your input via email. In addition, if it generates a significant shift in our thinking or is valuable to the broader community, we will repost it to this site. Finally, if you have interesting information you would like to share with the community, please send us an email.


The scope of DEIX includes “The what?” or the characterization of the content and relationships, involved in the exchange of digital artifacts. Its scope includes the following activities:

  • 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.

If you are interested in volunteering to help on the DEIX working group, please go to the International Council of Systems Engineers (INCOSE) working group and communities of practice website ( Then sign up for the Digital Engineering Information Exchange Working Group (DEIX WG).

DEIX Product Teams

This section includes the latest thinking and conclusions from the various DEIX working sessions. The intent is provide a sandbox for the entire Digital Engineering and Model-Based Engineering community to provide comments, suggestions, and questions to the latest thinking on digital engineering information exchange. As you review the latest thinking, please email the assigned facilitator for each Thought Area and provide your comments. The Thought Areas are listed below:

Topical Encyclopedia for Digital Engineering Information Exchange (DEIXPedia)

The product is a thematic micropedia of digital engineering topics with entries of 250 to 1,000 words. The objective is to explain 25 to 50 relevant topics by April 2019. The plan is to explain the latest DEIX related topics, achieve community acceptance, and evolve the topics. The effort is to create and evolve the topics based on published research, thought-leadership, and common usage by the engineering community. An analogous product may be additions to an online encyclopedia like “ SEBoK”, a DEIX reference e-book, an executive primer booklet, or a special issue journal or periodical. This product should provide in-depth explanation of thematic topics that allow the digital engineering community to properly express the digital information they request, offer, or exchange.

Digital Engineering Information Exchange Model (DEIXM)

The goal is to develop a Digital Engineering Information Exchange Model (DEIXM) that describes the information exchange for model-centric digital artifacts in an Digital Engineering Ecosystem. Analogous products may include the National Information Exchange Model (NIEM), using the OMG Information Exchange Framework (IEF) to create the DEIXM, or a Digital Ecosystem Reference Architecture. The effort is to create a reference model that allows participants to exchange information in a model-centric engineering ecosystem. The DEIXM should define what is exchanged, who is exchanging, types of exchanges, and how to offer & request exchanges of graphical and non-graphical engineering models.

Digital Viewpoint Model (DVM)

This is a model to create digital viewpoints that takes advantage of digital technology and modeling concepts to satisfy stakeholders’ information needs as it relates to systems engineering (SE) lifecycle standards such as ISO/IEC/IEEE 15288, 15289, 15504-6, 12207, 26531 and 24748. An analogous product might be a software controller based on Interaction Flow Modeling Language (IFML) to design a digital view for any SE lifecycle review. The effort is to decide on formalisms and conventions for a generic digital viewpoint model that stakeholders can use to offer or requests digital artifacts for any systems engineering lifecycle review. This involves identifying the digital artifacts, designing a generic digital viewpoint that generates interactive digital views to meet stakeholders’ needs.

DEIX Standards Framework

Think of National Building Information Model Standard (NBIMS).  The finished product is guidance that references other existing, revising, or pending standards that facilitate the sharing of model-centric information.  The DEIX-SF provides industry-wide agreements on standards or conventions to enable a universal exchange of digital artifacts between disciplines, buyers, and suppliers in a global supply chain.

List of DEIX Topics for Development

The list below is the current list of concepts related to DEIX. The concepts in the list with hyperlinks have current encyclopedia entries that are open for review and comment from the community.
