Tailoring the Harmony/SE MBSE method for automotive paper

For those that have asked, these are the links to the Tailoring the Harmony/SE MBSE method for automotive TailoringTheHarmonySE-MBSEMethod-ForAutomotive-V4.pdf paper that I delivered at the INCOSE UK ASEC 2017 conference in November. Here's the abstract:

Abstract. The Harmony/Systems Engineering (SE) process is a Model-based Systems Engineering (MBSE) process originated by Hans-Peter Hoffmann Ph.D. (i-Logix, Telelogic, IBM) based on work by Harel (Harel, Politi 1998). First published as “Harmony/SE” in 2006, it exploited the executable modelling features of the i-Logix Rhapsody® UML tool, based on Harel statechart semantics (Harel, Kulger 1996) to build executable specifications of systems based on modelling use cases. Emphasizing the identification and allocation of desired functionality and state-based behavior rather than details of functional behavior, the method achieved strong usage in the traditional systems engineering markets such as aerospace and defense. With the explosion in the complexity of state orientated Advanced Driver Assistance Systems (ADAS) and other similar systems, this paper will overview the method but look at real experiences of tailoring the ideas of Harmony/SE with SysML in the automotive domain and how it is both similar and different to the traditional Systems Engineering market. The paper reflects the author’s own views rather than the views of automotive companies he has worked for (Jaguar Land Rover, Daimler AG). Aspects covered will include reflections on extending the method to support use of the state machine inheritance, use of simulations and/or lightweight modelling to engage stakeholders, and – importantly – the human aspects including adjusting UML/SysML usage to ease absorption by an automotive control engineer community.


For those that don't know, the Annual Systems Engineering Conference (ASEC) is INCOSE UK's flagship annual event and brings together a wide range of professionals from a variety of backgrounds, with the common interest of building upon their Systems Engineering (SE) knowledge and sharing ideas with their peers. The focus of the conference was "Pushing the boundaries of systems engineering".

The paper gives a lot more description than the slides. Here are the TailoringHarmonySEForAutomotive-WidescreenNoVideo-V3.pdf slides.
