Welcome to the SEBoK. SEBoK Original Work. Video was created by Rob Cloutier (2021 SEBoK Editor in Chief).
On behalf of the Editorial Board, the Governing Board, and our authors and sponsors, welcome to SEBoK version 2.6.

Welcome to SEBoK v. 2.6

The SEBoK provides a guide to the key knowledge sources and references of systems engineeringsystems engineering organized and explained to assist a wide variety of individuals. It is a living product, accepting community input continuously, with regular refreshes and updates. The SEBoK is a not compendium but instead references existing literature and much of the content has restricted intellectual property rights.

Systems engineering is an interdisciplinary approach and means to enable the full life cycle of successful productproduct, serviceservice and enterpriseenterprise systems. It includes problem discovery and formulation, solution definition and realization, and operational use, sustainment, and disposal. It can be applied to single problem situations or to the management of multiple interventions in commercial or public enterprises. Those new to systems engineering can find introductory articles which provide an overview of systems engineering, place it in historical context, and discuss its economic value in Part 1 of this body of knowledge.

What's New?


A few things to look forward to in the latest update:

  • Parts 2 and 3 - the foundations of systems engineering and systems engineering approaches, methods, processes, and tools have been substantially rearranged. This update reflects:
    • Incorporation of more information on Model-Based Systems Engineering (MBSE) and Digital Engineering
    • Refinement of systems science foundations of systems engineering
    • Addition of new materials in Part 3 such as agile approaches.
  • Part 6 - there are many new articles and updates to existing articles on the relationships between systems engineering and other disciplines.
  • New Editor's Corner - the Editor's Corner is focused on the current and emerging trends in systems engineering. Check it out for our Editor in Chief's current thoughts on the metaverse and the impact on systems.
  • New sponsors and sponsorship packages - you will notice a number of new sponsors and updates to the sponsorship packages available. Please join us in thanking our sponsors for their support of the SEBoK!
  • The SEBoK user community has provided dozens of comments - from minor corrections to recommendations on terminology and reference updates to broad discussions about the transformation of the discipline. The Editorial Board has addressed all resolved comments in the wiki and will carry forward any comments still under discussion in version 2.6.

The SEBoK is a guide to the broad scope of SE-related knowledge. The core of this is tested and proven knowledge that has been developed through practice, documented, reviewed, and discussed by the SE community. In addition, the SEBoK also covers some of the emerging aspects of SE practice, such as Systems of Systems, Agile Life Cycle approaches and Model Based Systems Engineering (MBSE).

Systems engineering has its roots in the fundamentals, principles, and models of foundational systems sciences, and associated management and engineering sciences. It is effective systems engineering processes are applied within a managed life cycle working with a number of other management, engineering, and specialist disciplines. While traditionally applied to product development, systems engineering can also be applied to serviceservice and enterpriseenterprise systems. As systems engineering is a collaborative approach, working with other engineering and management disciplines and specialties, it relies on competencies at the individual and team levels and appropriate structure and governance at organizational levels.

Starting from this basic view of the scope of knowledge relevant to SE, the SEBoK is organized into 8 parts as shown in Figure 1. Click on Figure 1 to navigate to any part of the SEBoK.

The SEBoK includes a glossary and a list of recommended references. The main content of the SEBoK can be downloaded as a PDF for offline access if desired.

SEBoK Governance

The SEBoK is overseen by the Governing Board appointed by the stewards, who oversee the SEBoK Editor-in-Chief and Editorial Board. The stewards contribute resources to manage the SEBoK wiki, support new releases, and encourage SEBoK adoption. Volunteer authors from the worldwide SE community continue to propose and create new content. Other volunteers review that new content. The stewards are INCOSE, the IEEE Systems Council, and Stevens Institute of Technology.
