On behalf of the more than 70 authors, the editors, and the three SEBoK steward organizations – the International Council on Systems Engineering (INCOSE), the Institute of Electrical and Electronics Engineers Computer Society (IEEE-CS), and the Systems Engineering Research Center (SERC) – welcome to the Guide to the Systems Engineering Body of Knowledge (SEBoK) version 1.1.1. This version was released 14 June 2013, and contains a small number of content changes and wiki additions to version 1.1, which was released in April 2013.

The SEBoK provides a compendium of the key knowledge sources and references of systems engineering, organized and explained to assist a wide variety of users. It is a living document, accepting community input continuously, and regularly refreshed and updated.

About Systems Engineering

Systems engineering is an interdisciplinary approach and means to enable the realization of successful systems. Separate articles in Part 1 provide an overview of systems engineering, place it in historical context, and discuss its economic value.

Systems engineering has roots in systems science. Major sections (called knowledge areas (KAs)) in Part 2 discuss Systems Fundamentals, Systems Thinking, Representing Systems with Models, and the Systems Approach Applied to Engineered Systems.

About the SEBoK

The SEBoK is organized into 7 parts, with a Glossary of Terms and a list of Primary References.

The other parts include:

As a compendium, much of the content has restricted intellectual property rights. This copyright information is placed on each page, and must be respected. The SEBoK copyright is held by the Trustees of the Stevens Institute of Technology, and plans for the transfer of the copyright are discussed in the Editors' Note.

As a living document, at the bottom of each page, version identification can be found in a link called "About SEBoK 1.1."

A PDF of SEBoK v. 1.1 and the older SEBoK v. 1.0 may be downloaded at Download SEBoK PDF. Please note that a new PDF is not generated for micro releases, such as v. 1.1.1.

There is a link in the left margin under Quicklinks explaining how to Cite the SEBoK correctly.

About the Sandbox

The SEBoK is a moderated wiki. Comments are accepted on each page. To provide a larger forum for users to propose new content or revisions to existing content, the BKCASE editors are also developing a 'Sandbox'. The Sandbox is expected to be operational by late summer, 2013. When the Sandbox is operational, a micro-release will update the SEBoK with links to it.

Using the SEBoK

Articles in the SEBoK can be found by using the Search field in the upper right corner of each page, as well as through the Quicklinks, Outline, and Navigation menus in the left margin of each page. Detailed instructions about the page layout and features are found in How to Read the SEBoK.

Contact the Editors

Comments can be left on any page by using the DISQUS feature. These are periodically reviewed. Comments can be flagged in DISQUS, which will result in a faster review by the editors.
