Development of SEBoK v. 1.0

The development of SEBoK v. 1.0 was the work of 70 authors from around the world and took three years – from 2009 to 2012. The first three years of the project were sponsored by the Deputy Assistant Secretary of Defense for Systems Engineering (DASD(SE)), as outlined in detail below. The author team developed 3 draft versions of the SEBoK and received over 3,000 review comments from over 300 reviewers. Complete details on the team that built SEBoK v. 1.0 can be found below.

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, v. 1.0 was release in September 2012.

After the release of v. 1.0, the BKCASE Governing Board was established; the Governing Board is made of representatives from the International Council on Systems Engineering (INCOSE), the IEEE Computer Society, and the Systems Engineering Research Center (SERC).

History, Motivation, and Value

The Body of Knowledge and Curriculum to Advance Systems Engineering Project (BKCASE), which began in the fall of 2009, created a community-based Guide to the Systems Engineering Body of Knowledge (SEBoK) and a Graduate Reference Curriculum for Systems Engineering (GRCSE) (Pyster and Olwell et al. 2012) (Please see http://www.bkcase.org for more information). The SEBoK came into being out of a recognition that the systems engineering (SE) discipline could benefit greatly by having a living authoritative guide that discusses what is included in the discipline, how the discipline should be structured to facilitate understanding, and what documents are the most important to the discipline. A key principle of the BKCASE project is that the SEBoK and GRCSE will always be available free worldwide – including the revisions to those products.

Through the end of 2012, BKCASE was led by Stevens Institute of Technology and the Naval Postgraduate School in coordination with several professional societies and sponsored by the U.S. Department of Defense (DoD), which provided generous funding. Volunteers from dozens of companies, universities, and professional societies across 10 countries contributed many thousands of hours writing the SEBoK articles; their organizations provided significant other contributions in-kind. For additional information on the BKCASE authors, please see the Acknowledgements article.

The scale and complexity of BKCASE emerged over the first few months of the project. Systems engineering is large and relatively immature when compared to more classic engineering disciplines, such as electrical and mechanical engineering. We are extremely pleased with how the community rose to the challenge. New authors continually stepped up when gaps in the writing team were identified and we routinely assembled 25 to 30 authors every three months in a multi-day workshop to iron out issues and make key decisions.

One of the most critical decisions occurred in January 2011, when the team confirmed a switch to a wiki-based presentation for the body of knowledge. This added much complexity to the effort, but offered great advantages in terms of the modularity for update, access to interim material by the authors, easy review and suggestions for improvements, and flexible navigation. In hindsight, the impact of choosing a wiki was much greater than we understood, but we are very happy we went down that path. We believe this format to present the body of knowledge will serve the SE community much better than if we had produced a traditional PDF or Word document.

The SEBoK is intended to evolve and morph with use and with changes in the field. The wiki structure is particularly well-suited for promoting that purpose. Users are asked to comment about what they like and dislike, what is missing and what should be removed. New articles will be added and existing articles updated regularly.

Original Editor-in-Chief and Co-Editor-in-Chief

The original BKCASE project was lead by Editor in Chief Art Pyster and Co-Editor in Chief Dave Olwell, who served from 2009 through early 2014. Without their leadership, vision, and drive the project would not have succeeded.

Original Sponsor

The Department of Defense (DoD) recognizes the importance of SEBoK to its own workforce development and has provided substantial financial support and partnership to the BKCASE project. The office of the Deputy Assistant Secretary of Defense for Systems Engineering (DASD(SE)) is the original Department of Defense sponsor for the BKCASE Project. DASD(SE) graciously provided much of the funding for SEBoK development through their Systems Engineering Research Center (SERC) (see http://www.sercuarc.org). Those funds have primarily paid for the time spent by the SEBoK leadership, enabled the many volunteer authors to conduct quarterly physical workshops, and provided for the technical and administrative infrastructure to conduct such a complex distributed project. DASD(SE) has not determined the content of the SEBoK, but instead has allowed the author team and the community to determine what the SEBoK should contain. Without this support over the life of the project, the creation of the SEBoK would not have been possible. Moreover, DASD(SE) has continued to provide substantial support to BKCASE in 2013 through the SERC. Special thanks go to Stephen Welby, Kristen Baldwin, Nicholas Torelli, Don Gelosh, Scott Lucero, and Darren Dusza for their support throughout the BKCASE lifetime.

Part Team Leads

The SEBoK is divided into seven primary Parts (see SEBoK Table of Contents). Through the release of SEBoK v. 1.0, someone graciously volunteered to lead a team of authors in writing the articles and coordinating article integration for each of the Parts. This was an enormous amount of work. We would like to thank each of these individuals for their time, dedication, and leadership. In addition, a member of the editorial staff supported each of the part team leads.

Part 1 - Barry Boehm
Part 2 - Richard Adcock
Part 3 - Garry Roedler
Part 4 - Harold (Bud) Lawson
Part 5 - Art Pyster
Part 6 - David Olwell
Part 7 - Heidi Davidz

Authors

As a primarily volunteer effort, the BKCASE project depended on dozens of authors from around the world to provide their own time and expenses. Each of the individuals listed below worked many hours to develop and improve SEBoK v. 1.0 and GRCSE v. 1.0. Without each of them, it would have been impossible to succeed. Many of them were supported by their organizations during this effort, including support for travel and labor, and we also gratefully acknowledge the organizational contributions.

SEBoK Reviewers

Reviewers are critical to the success and growth of the SEBoK. By providing feedback that represents the diversity of views and opinions on systems engineering, reviewers help the author team identify and describe ground truths for SE as well as areas of contention. The reviewers who provided feedback for earlier versions are listed in Table 3, below. In addition, there are a number of other reviewers who provided their comments directly on the wiki with only a user ID (and not a full name) and reviewers who were part of a group that provided a collective review; these reviewers are not listed in Table 3. Many thanks to all reviewers!

The author team would like to particularly acknowledge the efforts of several INCOSE working groups (WGs) who provided feedback:

Systems Science WG
Architecture WG
Requirements WG
Decision Analysis WG
In Service WG
Lean Systems Engineering WG
System of Systems WG
Process Improvement WG

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 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 0.75

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 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 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.
