| − | Systems engineering (SE) is an activity that is success-critical for many human endeavors. Today, SE is increasingly recognized worldwide for its importance in enabling the development, deployment, operation, and evolution of systems with a wide variety of scale, complexity, and purpose. | + | The purpose of the ''Guide to the Systems Engineering Body of Knowledge (SEBoK)'' is to provide a widely accepted, community-based, and regularly updated baseline of {{Term|Systems Engineering (glossary)}} (SE) knowledge. SEBoK Part 1 contains an introduction to both the discipline of SE, and an introduction to and guide for the use of the SEBoK wiki. |

| | + | Part 1 also includes an introduction to some of the emerging aspects of systems engineering and a discussion of how these are transforming the discipline. As this knowledge matures, it will be migrated into the main body of the SEBoK. |
| | | | |
| − | The Guide to the Systems Engineering Body of Knowledge (SEBoK) defines and organizes the knowledge of the systems engineering (SE) discipline, including its vocabulary, concepts, methods, processes, practices, and tools. It is not an inclusive compendium of all SE knowledge, which is far too large and dynamic to be captured in any single place. Rather, the SEBoK is a portal that guides the user in finding and understanding the expanse of information about SE which has been separately published in books, articles, websites, and other generally accessible resources. All references included in the SEBoK are generally available to any interested reader (i.e., no proprietary information is referenced), but they are not all free (e.g., some books or standards that must be purchased from their publishers). The criterion for inclusion is simply that the authors believed it was among the best generally available sources of information on a particular subject.
| + | ==Part 1 Knowledge Areas== |
| − | | + | Each part of the SEBoK is divided into knowledge areas (KAs), which are groupings of information with a related theme. Part 1 contains the following KAs: |

| − | ==Purpose of the SEBoK==
| |
| − | The purpose of the SEBoK is to provide an evolvable community-consensus baseline body of knowledge that can serve as a working set of definitions, principles, processes, and good practices for the SE field. It is intended to describe the boundaries, terminology, content, and structure of systems engineering (SE) that are needed to systematically and consistently support the six broad purposes shown in Table 1.

| − | The SEBoK is intended to be a guide to the body of knowledge, but does not seek to capture all the knowledge directly. It provides references to more detailed sources of knowledge, and is constructed to facilitate easy update as the field evolves and new sources of knowledge emerge. The SEBoK is also intended to be global in applicability. Despite the challenge that SE is practiced differently from industry to industry and country to country, the SEBoK must be useful to systems engineers around the world. The authors have been chosen from a diverse set of locales and industries to help ensure its broad applicability. With the opening of version 0.5 (the current version) for global review, the authors hope to gain feedback that will enable them to refine the SEBoK into something that is even more universally applicable.

| |
| − | The SEBoK should inform a wide variety of user communities on essential SE concepts and practices, in ways that can be tailored to different enterprises and activities, while retaining more commonality and consistency than is currently possible. The dynamism of the world in which SE is being applied will require continuing update of the SEBoK.
| |

| |
| − | ==Scope of the SEBoK==
| |
| − | The majority of the SEBoK (Parts 2 – 6) focuses on domain-independent information – that which is universal to systems engineering regardless of the domain in which it is applied. Part 7 includes examples from real projects, which illustrate the concepts discussed in elsewhere in the SEBoK. As real examples, these include considerations relevant to specific domains, such as aerospace, medical, and transportation. The SEBoK is primarily focused on SE in the context of [[Engineered System (glossary)|Engineered Systems (glossary)]] [[Acronyms|(ES)]], though general systems concepts are also discussed in Part 2 [[Systems]]. Finally, the SEBoK includes considerations for closely-related disciplines; i.e., disciplines such as software engineering and project management, which are strongly entangled with the practice of SE. Please see the [[Scope of the SEBoK]] article for additional information.

| − | ==Systems and Systems Engineering==
| |
| − | In order to create the SEBoK, the authors began by defining what is meant by the terms “system” and “systems engineering”. There is controversy about how these terms should be defined and used within the SE community and as such, there are many different definitions. The SEBoK authors have chosen constructs for “system” and “systems engineering” that are useful, but recognize that they will not be considered “right” by the entire community.
| |
| − |
| |
| − | For the purposes of the SEBoK, a system is primarily defined as "a set of related elements that form an integrated whole" (Bertalanffy 1968) and which exists in an environment which contains related systems and conditions. While there are many definitions of the word system, the authors believe that this definition is comprehensive enough to encompass most of those which are relevant to systems engineering. The SEBoK also specifically defines an engineered system as an open, concrete system of technical or sociotechnical elements that exhibits emergent properties not exhibited by its individual elements. Its characteristics include being created by and for people; having a purpose, with multiple views; satisfying key stakeholders’ value propositions; having a life cycle and evolution dynamics; having a boundary and an external environment; and being a part of a system-of-interest hierarchy.
| |
| − |
| |
| − | For the purposes of the SEBoK, systems engineering is defined as an interdisciplinary approach and means to enable the realization of successful systems. It focuses on holistically and concurrently understanding stakeholder needs; exploring opportunities; documenting requirements; and synthesizing, verifying, validating, and evolving solutions while considering the complete problem, from system concept exploration through system disposal.
| |
| − |
| |
| − | These terms can be found in the glossary [http://sebokwiki.org/index.php/Category:Glossary_of_Terms]. Readers should note that in addition to the recommended definition(s) provided, there is also discussion of other existing definitions, how these definitions came about, and where within the community these other definitions are used. For more discussion on the definition of systems, please see the [[What is a System?]] article; for more on systems engineering, please see [[Systems Engineering and Management|Part 3]].

| − | ==SEBoK Uses==
| |
| − | Early in the BKCASE project, the [[Acknowledgements#Authors|authors]] identified potential users of the SEBoK and ways in which these individuals might utilize the information found in the SEBoK. This information was included in version 0.25, which was released for limited review in September 2010. (See “SEBoK Development,” below.) Based on this review, the authors refined the list of users and use cases, which can be found in the article [[SEBoK Users and Uses]]. This discussion includes consideration of primary users – those who will directly use the SEBoK – and secondary users – those who are expected to require assistance from a systems engineer to utilize the SEBoK. For more information, please see the [[SEBoK Users and Uses]] article.

| − | ==SEBoK Development==
| |
| − | The first version of the SEBoK – a prototype labeled Version 0.25 – was released as a PDF document for limited review in September 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. With this input, the authors began development of Version 0.5 – the current draft version – believed to be close in structure to the final version.
| |
| | | | |
| − | In January 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 offer feedback while keeping the content of the SEBoK stable between versions. For more information, please see the [[SEBoK Evolution]] article.
| + | ==Scope and Context of the SEBoK== |
| | + | While Part 1 introduces Systems Engineering knowledge areas, the remaining SEBoK content (Parts 2 – 6) focuses on domain-independent information—that which is universal to systems engineering regardless of the domain in which it is applied. Part 7 includes examples from real projects. These illustrate the concepts discussed elsewhere in the SEBoK, while detailing considerations relevant to domains such as aerospace, medicine, and transportation. |
| | | | |
| | + | SE in the context of engineered systems (ES) is the primary scope for the SEBoK, though general systems concepts are also discussed in Part 2. The SEBoK also covers considerations for the disciplines of software engineering and project management, which are strongly intertwined with the practice of SE (see [[Related Disciplines|Part 6]]). |
