The BKCASE Editorial Board has made significant efforts to become more involved in activities within our sponsoring organizations on key topics such as model based systems engineering (MBSE), agile life cycles, systems of systems, systems engineering leadership, and Software Engineering.  SEBoK v1.4 also included changes which respond to the publication of [[ISO/IEC/IEEE 15288|ISO/IEC/IEEE. 15288:2015 Systems and Software Engineering - System Life Cycle Processes]] and the [[INCOSE Systems Engineering Handbook|INCOSE SE Handbook v4.0, 2015]], these changes continue to influence SEBoK evolution.

=== SEBoK v. 1.6 ===
 
  
SEBoK v1.6 includes a major reorganization of Part 1, SEBoK Introduction.  Part 1 has been divided into three knowledge areas (KA):

In 2008, I attended my first International Symposium of the International Council on Systems Engineering (INCOSE). I was near completing my master's in systems engineering and was excited to learn more from the broader community. At that Symposium, I attended a number of talks about something called "model-based systems engineering" (MBSE). I was dazzled by the vision presented: a hyper-networked set of tools that would allow information to flow seamlessly throughout the lifecycle. The tenor of the presentations - and all of the conversations - was that this evolutionary way of working was just around the corner.  
*[[Introduction to the SEBoK]]
 
*[[Introduction to Systems Engineering]]
 
*[[Introduction to SE Transformation]]
 
The first two KA contain modified versions of existing articles. The third is a new KA to reflect the changing nature of SE. While a discipline like SE is constantly changing, INCOSE and others have recognized that it is currently going through a significant transformation in a number of ways. We wish to include some aspects of that transformation in the SEBoK. The transformation KA defines the scope of the transformation and contains articles which give details about specific aspects of transformational knowledge.  The intention is to use this KA to introduce new knowledge and then to transition it into the main body of the SEBoK.
 
The transformation KA for v1.6 covers two key aspects of the transformation of SE:
 
*[[Transitioning Systems Engineering to a Model-based Discipline|Transition to a Model Based Discipline]]
 
*Expansion of the cross domain nature of SE
 
For the first we have a new article giving an overview of Model Based Systems Engineering (MBSE).  For the second two new articles give an overview of [[Healthcare Systems Engineering|healthcare SE]].  This is the first inclusion of domain specific practices in the SEBoK.
 
  
We have also made a number of small changes in response to comments made on the SEBoK by people in the SE community. Many thanks for everyone who has taken the time to leave comments and suggestion in the SEBoK.

Today, I have had the privilege of working in the Digital Engineering space for the last five years. And what I am constantly hearing is that we need digital engineering, but that there is frustration about the benefits not being realized quickly. So why is this?
  
===Future Direction for SEBoK===
+
Historically, Wymore laid the foundations for MBSE in his 1993 book. From this foundation, it took 10 years for Systems Modeling Language (SysML) to be established. It took a further four years before INCOSE established an MBSE initiative. So by the time I was first hearing about MBSE in 2008, the concept had actually been percolating through the field for 15 years. As I learned more about it, I began to understand just how far the reality of systems engineering practice was from the vision of MBSE.
  
It has been my continuing privilege over the last 12 months to continue working with the group of dedicated and knowledgeable [[Acknowledgements and Release History|contributing authors and reviewers]] who make up the BKCASE community; and to help grow this community to expand our relationships with key organizations and groups both within systems engineering and outside of it.  
+
The term "digital engineering" gained traction in the mid-2010s, with a firm anchor established in 2018 with the US Department of Defense's ''Digital Engineering Strategy''. The term digital engineering is used in a variety of ways, but I generally like this definition: an integrated digital approach that uses authoritative sources of systems' data and models as a continuum across disciplines to support lifecycle activities from concept through disposal. (DAU 2023) In other words, it's using trusted data and models to engineer systems in a digital way. This is similar to the promise of MBSE that I was first introduced to in 2008.
  
The role of the Editorial Board is to work with this community of interest on an ongoing review of the current SEBoK content and structure and to develop plans for its maintenance and evolution. Our overall goals in evolving the SEBoK remain broadly the same as those outlined in previous SEBoK updates.  I have restated and slightly modified those goals below:
+
Why is it, then, that digital engineering is not moving as quickly as we'd like?
  
*Improve the ways in which [[SEBoK Introduction|Part 1 (SEBoK Introduction)]] provides a starting point for different SEBoK users to find and navigate knowledge relevant to them.  This will include consideration of some of the [[SEBoK Users and Uses|SEBoK Use Cases]] which were not expanded in previous releases, and possible new case studies covering application domains such as Defense, Health Care or Transport.  
+
I would propose that the term "digital engineering" in and of itself is a challenge. I have heard for years at community events that "MBSE" is really just systems engineering using models. Many have expressed concerns that by calling it something separate, we've created artificial silos between MBSE and "other systems engineering". The same seems to be true for digital engineering. Adding to this challenge is the distinction - or lack thereof - between digital engineering and MBSE. At conferences in the last few years, I've seen tracks for MBSE and digital engineering completely separated in our programs. While most of the community knows there is a close relationship between the two, we send conflicting signals in the way that we communicate them.   
*Review Part 2 ([[Foundations of Systems Engineering]]) with help from the International Society for the Systems Sciences (ISSS) to better understand the relationships between [[Systems Science (glossary)]] and [[Systems Thinking (glossary)]] as applied to [[Engineered System (glossary)|engineered systems]]. We hope this will lead to an improved integration of systems principles, concepts, patterns and models into the other systems engineering focused knowledge areas across the SEBoK.  
 
*Look for broader views on the key practices of [[Systems Engineering and Management|Part 3 (Systems Engineering and Management)]] to feed back into the ongoing co evolution of key standards. In particular make more direct reference to the continuing evolution of [[Agile (glossary)|Agile]] life cycle thinking and bring in more knowledge sources from the [[Model-Based Systems Engineering (MBSE) (glossary)|model based SE (MBSE)]] community.
 
*Expand our coverage of knowledge on systems engineering application and practices. In particular look for ways to bring in more knowledge on how systems engineering practices such as architecting, life cycle tailoring and model based systems engineering are applied in other domains.
 
*Identify the other groups, both within the systems engineering community and beyond, with interest in the topics of [[Enabling Systems Engineering|Part 5 (Enabling Systems Engineering)]] and [[Related Disciplines|Part 6 Related Disciplines]] and form stronger relationships with them.  For example we are working with the IEEE Computer Society about the relationship between SE and Software Engineering.
 
  
In 2016 we will slightly modify the SEBoK release dates, moving from June and Dec to March and Sept.  This will allow us to better align the publishing schedule with our working sessions at INCOSE and IEEE-CS international events. We continue to work towards ensuring that our coverage of existing systems engineering knowledge is complete and to push the boundaries of that knowledge into new approaches and domains. I also want to strengthen further our links to all members of the systems engineering community through things like the [[Sandbox|SEBoK Sandbox]]. If you are interested in any of the activity discussed above or if you have other topics which we should be considering please contact me or the appropriate member of the [[BKCASE Governance and Editorial Board|Editorial Board]] directly or use one of the available feedback mechanisms.

True "digital engineering" really goes beyond just engineering activities. While I would define digital engineering as "doing systems engineering in a digital way", this requires a fully integrated digital environment - a complex technical challenge in and of itself. Organizations that put forth the time and energy to establish such an environment should, therefore, not limit itself in scope to only data and tools that support systems engineering. It would be extremely inefficient, for example, to not also include tools that support project lifecycle management activities, even if much of this data falls under "project management" rather than systems engineering. If we as systems engineers truly see the world in systems, we need to treat the creation of digital environments systemically as well. We have to acknowledge that our digital environments should support all of our team members, not just systems engineers. What we are really talking about is broad digital transformation. By continually communicating this as an "engineering" problem, we make it more difficult to help our leaders, decision-makers, managers, and other critical team members to buy into our vision. The language may also create some tension with other engineering disciplines that have been utilizing data and digital models for decades.
  
We have made a good start on gathering review comments and content suggestions from as wide a variety of individuals as possible to make the SEBoK a truly community-led product.  Thank you to all those who have already joined this effort and I continue to look forward to working with many of you on future SEBoK releases.
+
Digital engineering is also resource-intensive. The intention and hope are that once digital environments and approaches are well-established, they will decrease cycle times, make systems more financially effective, and improve our ability to build the systems that the world needs. However, until those things are established, there is a lot of work to be done and time and money invested to get there. Digital engineering can and will cost more and take more time upfront. That is a difficult pill to swallow when one of the foremost selling points for digital engineering is increased efficiency.
  
Thank you,

All of these are challenges to full digital transformation, but there is hope. Based on observations over the last several years, there are pockets of excellence, where organizations are pushing the boundaries of what we can do in the digital space and more and more, people are buying into the value proposition. Now we have to deliver on that value by coming together as a community. Humbly, I share a few thoughts for this:

*'''As a community, we need to create a clear framework for how all of the pieces fit together.''' Is MBSE a part of digital engineering? Is digital engineering a part of systems engineering or is systems engineering a subset of digital engineering? There is a proliferation of opinions on this and until we as a community find some consistency in the way we discuss these things together, it will be almost impossible for us to build a consistent vision with our colleagues in other disciplines.
 +
*'''We need to share our challenges more openly.''' I hear the same issues and concerns from people throughout the community, but we are not always willing to share our failings. True digital engineering is too complex for any one organization to fully solve in isolation. We need to be willing to share more specifics about what isn't working so that we can learn from one another's failures, rather than repeating them.
 +
*'''We need to share success stories.''' Just like with our failures, examples of something that worked - and some insight into the context in which it worked - will provide energy and momentum for us all to build upon.
 +
*'''We need to set more reasonable expectations about the digital transformation we're living through.''' If MBSE was still "fairly new" 15 years in, it is wholly unreasonable to believe that digital engineering will propagate throughout the discipline in a few years. True digital transformation will require shifts in our processes and approaches, organizational cultures, and expectations. These changes are slow. A roadmap that would help set expectations for when certain benefits may be realized would go a long way to building buy-in from our colleagues and organizations.

These are a few thoughts from the last several years of observing the community. ''What have you seen in your experiences with digital engineering?'' I encourage you to share your thoughts and views in the comments below. We look forward to learning from each of you and continuing the conversation.

What's the holdup with Digital Engineering?

In 2008, I attended my first International Symposium of the International Council on Systems Engineering (INCOSE). I was near completing my master's in systems engineering and was excited to learn more from the broader community. At that Symposium, I attended a number of talks about something called "model-based systems engineering" (MBSE).
