Previous Work

Previous work to develop a guide to the systems engineering (SE) body of knowledge includes an International Council on Systems Engineering (INCOSE) sponsored online version of the Guide to the Systems Engineering Body of Knowledge (G2SEBOK) (INCOSE 2002). The G2SEBOK effort, which ended around 2004, is unrelated to BKCASE and the SEBoK despite the similarity in name. The INCOSE SE Handbook is quite popular and has continued to evolve, and has been the de facto community statement of systems engineering (SE) knowledge and structure until the SEBoK (INCOSE 2012).

Systems engineering (SE) knowledge has also been documented through the standards bodies, including ISO/IEC/IEEE 15288 Systems Engineering-System Life Cycle Processes (2008), IEEE/EIA 12207 Software Life Cycle Processes (2008), and ANSI/EIA 632 Processes for Engineering a System (2003).

These efforts offer a foundation for the SEBoK, which goes beyond them by providing a comprehensive and regularly refreshed view of all SE knowledge.

SEBoK Releases

There have been 7 previous releases of the SEBoK:

  • Version 0.25 – A prototype that would create the first architecture and early content of the SEBoK for limited review and validation.
  • Version 0.5 – A version suitable for early adopters.
  • Version 0.75 – An interim version used to gather further community feedback and to address the most critical shortcomings identified in version 0.5.
  • Version 1.0 – The first version intended for broad use.
  • Version 1.0.1 – A micro update to version 1.0 which fixed spelling errors and other simple problems. No substantial changes in content were made.
  • Version 1.1 - A minor update to version 1.0.1 that made modest content improvements.
  • Version 1.1.1 - A micro update to version 1.1 that made improvements to wiki structure and function.

SEBoK Version 0.25

The first version of the SEBoK – a prototype labeled version 0.25 – was released as a document for limited review in September of 2010. A total of 3135 comments were received on this document from 114 reviewers across 17 countries. The author team reviewed these comments, paying particular attention to the reviews related to content and highlighting diversity within the community. The adjudication of version 0.25 comments may be seen here.

SEBoK Version 0.5

In January of 2011, the authors agreed to transition from a document-based SEBoK to a wiki-based SEBoK, with the intent to make the information readily accessible worldwide, provide additional methods for searching and navigating the content, and provide a forum for the community to provide feedback while keeping the content of the SEBoK stable between versions.

This second version of the SEBoK was released for world-wide comment in September of 2011. About 500 comments from approximately 40 reviewers were received. Selected comments were addressed in version 0.75, while others were deferred until version 1.0.

SEBoK Version 0.75

Based on the review comments, the authors first began by reorganizing the SEBoK to better align with the types of information included. The architecture was amended to add a handful of new articles and also about a third of the articles were revised.

SEBoK Version 1.0

Version 1.0, released in September of 2012, was the first version for broad community use. It made further revisions to the architecture, through adding, deleting, and moving articles. Most of the issues from the 0.5 and 0.75 reviews that had been deferred were addressed, though some issues were deferred to post-version 1.0 releases. All comments from all previous review cycles were entered into the final adjudication matrix and addressed. Additional wiki enhancements were added.

SEBoK Version 1.0.1

This micro update, released in November of 2012, fixed a number of spelling and grammatical errors, corrects errors in acknowledgments, and made other very modest improvements to version 1.0 of the SEBoK. There were no edits to individual articles to: improve clarity or content, add references to new publications since version 1.0 was released, improve wiki navigation and operation, or make other more substantial changes. Comments from version 1.0 were collected and archived for adjudication in version 1.1 or later.

SEBoK Version 1.1

This minor update was released in April 2013. It updated many topic articles and glossary articles. Changes included:

  • Fourteen topic articles were updated in Parts 1, 2, 3, and 6, for the purpose of expanding or improving the explanation of the topic, or in some cases to add new references.
  • Sixteen glossary terms were updated and two new glossary terms were added.
  • The Acknowledgements page was updated to reflect the significantly revised governance structure for the SEBoK, which added many new contributors in varying roles.
  • The Main Page and other Quicklinks pages were modified to reflect the new version.
  • The SEBoK Evolution article formerly in SEBoK v. 1.1 Introduction was deleted, being replaced by an updated version, being this Editor's Note article.

SEBoK Version 1.1.1

This micro update was released in June 2013. It was primarily focused on updates to the wiki structure and features. Changes included:

  • Version numbers were removed from page titles to improve maintenance of links
  • Spelling errors in contributor names were corrected.
  • 'Cite This Page' was revised and improved.
  • A few references were updated, notably in the Safety Engineering article.
  • Meta-tags were improved to increase visibility to search engines
  • Wiki navigational features --- especially breadcrumbs --- were been improved.
  • A counter was added to record PDF down-loads.

SEBoK Version 1.1.2

This micro updated is release in August 2013. It primarily focuses on updates to the wiki structure and features, including

  • Version numbers have been removed from page titles to improve maintenance of links
  • To reflect the governance of the SEBoK and oversight through the Editorial Board, a new page has been added called Meet the Editors.
  • A few references have been updated, notably in the Safety Engineering article.

The most significant change for this release is not to SEBoK v. 1.1.2 itself, but is the release of a companion wiki, the SEBoK Sandbox, which provides new collaborative opportunities to the community. In the Sandbox, any individual in the community will be able to edit or comment on existing SEBoK articles as well as request the creation of new SEBoK articles. The Sandbox is overseen by the Editorial Board. For more information, please visit the Sandbox.
