Modelling Services and Service-based systems

Relationship of SSE to MBSE

Work to transfer representation of the information on Stakeholder Interactions depicted in the Onion Diagram using SysML and Archimatew

(The Architectures Working Group have started a Workstream on this. WE can keep track of it.}

Relationship of using NAF and SysML with using Archimate/TOGAF

SW has used the standard SE modelling methods (SysML and NAF) and the Service Modelling tools (TOGAF and Archimate)

NAF and SysML

• NAF has emerged as the Architectures FrameWork basis for MBSE. It has some limitations that are not always appreciate.
• NAF is derived from DoDAF, MoDAF, and other NAFs that were developed tO cover areas of engineering that were seen as needing better coverage - such as MoDAF TEPIDOIL

• SySML WAS developed as an add-on to UML which itself was a set of three software development diagrams

Archimate/TOGAF

• These are both 'owned/supported' by The Open Group to provide process and implementation for services. They support each other and are used in development of business services.

Arcgchimate and SysML provide graphic languages for displaying engineering models ands so can be compared.

• ToGAPH provides a process for analysing, designing and developing services.

Findings so far are that Arcvhimate has entities that are suited to model humans in services. Using SysML. furthe entities need to be developed and used to cover the same entities.

Furtherv wrork = look at using Archimate Definitions/Entities

• See if we can map the Services Definitions Diagram on to Archimate Views (or Viewpoints)?

ASEC2021

• Ideas foe ASEC21 -may have people going depending on the programme.
• Develop Poster
• Presenting SSE activity/outputs*

Date of next meeting
