Attendees

In Work
Feedback from ASEC2010
General feedback
will be on the INCOSE UK website, overall the conference went well, but there were no major revelations.
The Group poster
was displayed and had some interest, but only casual - no-one saying this is what I need'.. Posters were on a display stand but unfortunately our poster was displayed on the side away from the main hall so we probably. The use of graphics and diagrams was attractive compared with other posters that were just words. Our use of MBSE was accepted - no-one said we had it wrong.
IT/Web Updates for all Groups
The INCOSE UK web site is moving to a new supplier and in the process will be upgraded. This will include:
- better handling for Users wishing to join
- creation of 'Core Groups' within each group who are active and doing the work
- ability to send out emails to group members instead of going to dot the eye to send out emailers
- ability to upload and remove documents
Informal Chats
- MBSE is generally accepted as the approach to Systems Engineering, but limited in scope to Requirements Analysis to Testing, rather than the full lifecycle.
- There were two groups with differing views on MBSE - The evangelists (as in Jon Holt's recent books), and the 'you don't need a tool. (as in Jon Holt's previous books)
- SysML is used as the language for use with MBSE projects,
- MODAF is not being widely used, however, some projects are failing in sorting out their training and support which MoDAF covers with Lines of Development.
- New versions of NAF are expected to be used.
- TOGAF and ArchiMate are being used by MoD and by other UK government departments. TOGAF is used for commercial service-based programmes so should be relevant for Service Systems Engineering.
Relationship of SSE to MBSE
The Relationship of Service Systems Engineering with Model Based Systems Engineering =was discussed at the last two meetings. It was decided to talk to/work with members of the MBSE Working Group but this has not happened. Mostly due to priorities and pressures of 'day jobs'
The relationship between the two can be understood as MBSE having a formal framework and tool support for the system requirements, design and testing, and SSE covering all aspects of systems provided by services.
Stakeholder interaction and representation
Presentation and discussion focussed on capture and representation of Stakeholders. How the information on the Onion Diagram could be represented in SysML diagrams - either standard or modified. What relationships are needed between Stakeholders and between Stakeholders and other elements.
The use of Service Elements on SysML diagrams was looked at briefly. This looks promising, but the limitation of MBSE/SysML in the lifecycle is an issue.
The Ontology for Service Systems need to be developed and understood.
The work done on Definitions for Services and the relationships between these definitions is not the same as the Ontology needed for MBSL, but is still an important aspect of the SSE work.
Date of next meeting
3rd February 2020, Filton 10-30 to 14-30
