Overview and the 6 W's

The current active thinking of the MBSE Adoption Guide structure is that it is based on 6 key questions, and from the perspectives of at least two stakeholders with respect to MBSE:

  • An individual systems engineer;
  • An engineering manager (with responsibility for a project, or organisational unit / department / function).

Current generic questions are proposed to be (JJ - have deliberately re-ordered to bring Why to top):

  1. Why should I adopt MBSE?
  2. What does MBSE mean for my role?
  3. Where (activity area, disciplines level of decomp) do I employ MBSE?
  4. When (temporal e.g. life cycle phase, criteria) should MBSE be employed?
  5. Who else needs to participate in, or will be impacted by the use of, MBSE activities?
  6. How do I make use of MBSE on my project?

A graphic illustrating this outline is available on the MBSE.org site here: 6-questions poster draft

Latest status

A Version 0.4 was evolved through to late 2017 and made available both in wiki and pdf formats (broadly identical). This went through a conventional review process, leading to a version v0.5 being produced (captured offline by JJ) which addressed many (although not all) of the comments and suggestions made. The initial version of the Adoption Guide now available on the wiki is that same v0.5 - however as authors update and extend that text on the wiki, it will of course deviate from the (JJ) basedlined version.

Case Studies

This section lists details of any case studies of application of MBSE, or adoption of MBSE, with appropriate supporting information, where that can be made available.

(to be populated).

FAQ

This section will evolve to contain frequently asked questions about MBSE and its adoption, with responses, supported by references where possible.

Don't Panic - The Absolute Beginner's Guide to Model_based Systems Engineering, Jon Holt and Simon Perry,INCOSE UK ltd, 2017 As the book back cover states: "(This book) aims to provide an honest, straightforward and simple introduction to the world of MBSE that almost anyone can understand." A short (~50 pp) book that does a quick gallop through MBSE: history, modelling (concept of), language (of modelling), art of (modelling), implementing MBSE, and best practice. Littered with sweet little handy icons for: pitfalls, myths, key concepts and benefits. link
Part 4, Transitioning to MBSE, in A Practical Guide to SysML, the Systems Modelling Language, 2nd edition, Friedenthal, Moore, Steiner, Morgan Kaufman Elsevier, 2012 Although the book itself focusses on SysML the modelling language, this Part has chapters exploring the role of the 'systems model' wrt other models, the use of tools and information flows between tools, and data exchange. It also looks at deploying SysML into an organisation, as part of a Improvement Process. link
Introducing MBSE by using Systems Engineering Principles, Jonas Hallqvist and Jonas Larsson, 26th Annual INCOSE International Symposium (IS 2016) Edinburgh, Scotland, UK, July 18-21, 2016 Describes one way to introduce MBSE in a company, in an aerospace context. After success on an initial pilot stody, adoption on a much large project was attempted, but stalled due to a number of issues. A systematic approach was adopted to understand all aspects of the transition to MBSE from the current situation: processes affected, incremental small steps, coordination, risk analysis, training. Subsequently a re-focus on systems engineering principles, including clarity on systems engineering purpose: describe different views of the systems architecture and design by using SysML in a modelling tool. Subsequently producing a model of their (MBSE) modelling environment, its capabilties, and its emergent properties (for instance, support for creating training material for the chosen method). A useful conclusion with many lessons-learned including: adopt holistic view to the change; keep focus on the why-change; think big, start small, evolve; prototype change, but beware scaleability; address all stakeholders; involve people that have gone through change before; ensure good leadership; form an effective commucation plan. link
Getting Started with MBSE in Product Development, Nichole Kass and James Kolozs, 26th Annual INCOSE International Symposium (IS 2016) Edinburgh, Scotland, UK, July 18-21, 2016 Prompted by concern about the complexity of default underlying MBSE schema, the authors developed a simplified schema that underpinning basic V lifecycle systems engineering processes, and cross-cutting concepts (traceability, definitions, documents, issues). The authors explain aspects of this simplied schema and its relationship to supporting systems engineering processes, and how even on larger, more complex projects, they adopt and then refine and extend this schema required for the specific project. link
