Where to Start with MBSE when Thousands of Sys Reqs Are Already Def | Thales AUS | Capella Days 2021

Where to Start with MBSE when Thousands of System Requirements Are Already Defined Presented by Peter Havenga and Laura Mallon (Thales Australia) Slides: https://mbse-capella.org/resources/pd... Context: The Thales OneSKY Australia Program is delivering a new Australia-wide integrated Civil and Military Air Traffic Management System, known as CMATS. CMATS replaces the current civilian Air Traffic Management (ATM) system and Defence ATM system, delivering the most advanced and integrated ATM system in the world. It will manage more than 11% of the earth’s airspace and will deliver Air Traffic Services to some of the world’s busiest air routes. Scope: Over the last 4 years of the Design phases of the program, the System-of-Systems Architecture team has defined and deployed a new way of working by focussing on capturing the system-of-systems architecture using state-of-the-art modelling techniques. A plan was put in place where the team collectively defined a target set of modelling goals in order to grow the team’s competency. Part of this plan was a roadmap for the longer term which focused on extending the current approach to further increase the business value of the architecture modelling activities. This approach has resulted in a stable working environment that not only allows the management of consistency and complexity, but also enables the team to collaboratively and efficiently work on the architecture definition, which has been critical during the recent working from home period and hectic project phases. The key Capella solutions that are used within this activity are the Team for Capella solution, application of the Requirements Viewpoint and the Property Value Management Tool. One of the important aspects of the modelling plan is to ensure information within the model can be used by the wider organisation, this is achieved through a Thales specific documentation generation solution and a bespoke csv export capability that allows to export data from the information captured in the architecture model. This talk will cover the modelling goals for this activity; where the team is standing today; the best practices and lessons learned. Creative commons BY-ND Licence: Attribution + NoDerivatives
