Model-Based Systems Engineering (MBSE) is the use of visual and diagrammatic techniques, as opposed to purely textual methods, to assist with the definition of Requirements, Design and Acceptance. It is a highly flexible methodology which uses a wide range of techniques to analyse a capability or system, and the environment and context in which it will operate, to define its behaviours, identify requirements and describe its verification and validation. It aims to break down highly complex challenges and enable engineers and stakeholders to understand the system and its operation.
In support of our Requirements and Acceptance work, we are adept at using a wide range of architecture and MBSE techniques to support our Systems Engineering capability. Our services include:
Architecture modelling, in frameworks such as NAF and TOGAF, creating Operational and System Views that contextualise a Capability and/or System within the environment in which it operates, helping to identify interfaces and dependencies;
MBSE techniques to assist with the development of Requirements and V&V, using SysML modelling tools such as CAMEO Systems Modeller, including:
- Use Cases
- Activity Diagrams
- Requirements and Block Diagrams
- System Boundary and Context Diagrams
We are adept at using these tools in support of Capability Development, rather than as an in in itself, utilising the work to support engagement with Stakeholders and assist with the identification of requirements, dependencies and interfaces, measures of effectiveness/performance and other requirements bounding statements.
