Introducing trinity – implementing MBSE into your organisation

The use of MBSE as an approach to realising successful Systems Engineering is becoming more prevalent as time goes on, leading to an anticipation that the INCOSE 2025 Vision that all Systems Engineering will be model based is looking increasingly likely.

Whilst the theory and practice of MBSE is becoming more mature, one of the biggest obstacles in realising the full benefits of an MBSE approach is how it is implemented in an organisation.

This talk is about implementing MBSE in an organisation, and draws on the authors’ decades of experience applying and deploying MBSE in companies of all sizes and introduces the Trinity approach to MBSE implementation. The three main considerations of implementation that form the heart of the Trinity approach are introduced as: reason, capability and evolution.

  • The reason behind wanting to implement MBSE is discussed by considering the context of the implementation. The reason, or the ‘why’ of MBSE is crucial and will drive all of our implementation activities.
  • The key aspects of MBSE that must be considered to establish MBSE capability are introduced in the form of the MBSE-in-a-slide diagram. This introduces the importance of the approach, the system and the notation. This is then expanded to include tools and best practice. This allows us to identify the capability of an organisation in terms of their current MBSE activities and their aspirations.
  • Once the capability has been covered, the concept of the evolution of MBSE is introduced as comprising five important stages, each of which has a number of outcomes associated with it. The organisation’s current stage and desired stage, based on the reason and capability considerations, are identified. The transition from one stage to another is then covered by identifying typical actions that must be undertaken when evolving MBSE from the starting stage to the final desired stage.

These three aspects come together to form the Trinity of MBSE implementation.

We will also describe some of the techniques that may be used to achieve an understanding of each, such as RAVEnS and TeamStorming

Prof Jon Holt is an internationally recognized expert in the field of Model-Based Systems Engineering (MBSE). He is an international award-winning author and public speaker and has authored 15 books on MBSE and its applications. Since 2014 he has been a Director and consultant for Scarecrow Consultants, who are ‘outstanding in the field of MBSE’. Jon is also a Professor of Systems Engineering at Cranfield University, where he is involved with the teaching of and research into MBSE. He is a Fellow of both the IET and the BCS and is a Chartered Engineer and Chartered IT Professional. Holt is currently the Technical Director of INCOSE UK, where he is responsible for all technical activities and, in 2015, was identified as one of the 25 most-influential Systems Engineers in the last 25 years by INCOSE. Jon is also actively involved in the promotion of Science Technology Engineering and Mathematics (STEM), where he uses magic, mind-reading and occasional escapology to promote Systems Engineering at Festivals, Cabarets, radio shows and other STEM events. He has also authored the children’s STEM book “Think Engineer,” which is published by INCOSE UK.
