View source for Introduction to the SEBoK

The SEBoK provides a widely accepted, community-based, and regularly updated baseline of [[Systems Engineering (glossary)]] (SE) knowledge. This baseline will strengthen the mutual understanding across the many disciplines involved in developing and operating systems. Shortfalls in such mutual understanding are a major source of system failures, which have increasingly severe impacts as systems become more global, interactive, and critical. Ongoing studies of system cost and schedule failures (Gruhl-Stutzke 2005; Johnson 2006) and safety failures (Leveson 2012) have shown that the failures have mostly come not from their domain disciplines, but from lack of adequate SE.

==Topics==
Each part of the SEBoK is divided into KAs, which are groupings of information with a related theme. The KAs in turn are divided into topics. This KA contains the following topics: 
*[[Scope of the SEBoK]]
*[[Structure of the SEBoK]]

==SEBoK Purposes==

To provide a foundation for the mutual understanding, the SEBoK describes the boundaries, terminology, content, and structure of SE. In so doing, the SEBoK systematically and consistently supports six broad purposes, described in Table 1.

!#
!Purpose
!Description
|-
|1
|Inform Practice
|Inform systems engineers about the boundaries, terminology, and structure of their discipline and point them to useful information needed to practice SE in any application domain.
|-
|2
|Inform Research
|Inform researchers about the limitations and gaps in current SE knowledge that should help guide their research agenda.  
|-
|3
|Inform Interactors
|Inform performers in interacting disciplines (system implementation, project and enterprise management, other disciplines) and other stakeholders of the nature and value of SE.
|-
|4
|Inform Curriculum Developers
|Inform organizations defining the content that should be common in undergraduate and graduate programs in SE.  
|-
|5
|Inform Certifiers
|Inform organizations certifying individuals as qualified to practice systems engineering.  
|-
|6
|Inform SE Staffing
|Inform organizations and managers deciding which competencies that practicing systems engineers should possess in various roles ranging from apprentice to expert.

The SEBoK is a guide to the body of SE knowledge, not an attempt to capture that knowledge directly. It provides references to more detailed sources of knowledge, all of which are generally available to any interested reader. No proprietary information is referenced, but not all referenced material is free—for example, some books or standards must be purchased from their publishers. The criterion for including a source is simply that the [[Acknowledgements and Release History|authors]] believed it offered the best generally available information on a particular subject.

The SEBoK is global in applicability. Although SE is practiced differently from industry to industry and country to country, the SEBoK is written to be useful to systems engineers anywhere. The authors were chosen from diverse locales and industries, and have refined the SEBoK to broaden applicability based on extensive global reviews of several drafts.

The SEBoK aims to inform a wide variety of user communities about essential SE concepts and practices, in ways that can be tailored to different enterprises and activities while retaining greater commonality and consistency than would be possible without the SEBoK. Because the world in which SE is being applied is evolving and dynamic, the SEBoK is designed for easy, continuous updating as new sources of knowledge emerge.

==SEBoK Uses==
The communities involved with SE include its various specialists, engineers from disciplines other than systems engineering, managers, researchers, and educators. This diversity means that there is no single best way to use the SEBoK. The SEBoK includes use cases that highlight ways that particular communities can draw upon the content of the SEBoK, identify articles of interest to those communities, and discuss primary users (those who use the SEBoK directly), and secondary users (those who use the SEBoK with assistance from a systems engineer). See the article [[SEBoK Users and Uses]].
