Four tenets of Systems Engineering from a Model-Based perspective
Model-based approach
Model-based Systems Engineering will become the “norm” for systems engineering execution…
INCOSE Systems Engineering Vision 2025
• Making the interconnectivity and interdependencies explicit
6Four tenets of Systems Engineering from a Model-Based perspective
A journey…
• Initial thoughts• Preliminary
• Introduction to deeper discussions
• Encourage comment and feedback.
7Four tenets of Systems Engineering from a Model-Based perspective
• Process of developing and managing requirements over project lifecycle
• Functional, non-functional requirements to be managed
• Shaping the project outcomes
• Communicate requirements between team members
8Four tenets of Systems Engineering from a Model-Based perspective
• Most researched from a model-based perspective
• Utilise the traceability
9Four tenets of Systems Engineering from a Model-Based perspective
• Elicited from functions and constraints.
• Assess system performance over lifecycle against requirements
• Fully, explicitly traceable within model
• Model-based methodology highlights traceability
10Four tenets of Systems Engineering from a Model-Based perspective
• Assessment of a view
• Check content and structure: both integral to quality products
11Four tenets of Systems Engineering from a Model-Based perspective
• Models richness of information• not reviewing a single document in isolation
• Non-trivial task as complex systems imply complex models, thus complex relationships
12Four tenets of Systems Engineering from a Model-Based perspective
• Review of meta-model, specific instantiation of meta-model, content of the model.
• Have to ensure views present themselves appropriately (content, structure, meta-model and analytical path)
13Four tenets of Systems Engineering from a Model-Based perspective
• Identify and analyse potential issues
• Work to remove / mitigate them

Four tenets of Systems Engineering from a Model-Based perspective
15Four tenets of Systems Engineering from a Model-Based perspective
• Fundamentally, process shouldn’t change
• Allocating to system aspects which generates and mitigates risk
• Model targets and supports risk management
• Directly evolve risk as system evolves
16Four tenets of Systems Engineering from a Model-Based perspective
• Establishing and maintaining consistency
• Operational, approval and legal baselines
17Four tenets of Systems Engineering from a Model-Based perspective
• Processes can be incorporated within the model
• Establish within central repository
• Regenerate view against baseline
18Four tenets of Systems Engineering from a Model-Based perspective
19Four tenets of Systems Engineering from a Model-Based perspective
• Introduce a new problem
• How to ensure CM of the model across those who need views from it?
• Open access, viewable, but with monitored & authorised control and modification
20Four tenets of Systems Engineering from a Model-Based perspective
Conclusion
• Identified benefits for the model providing support to the Engineering Management Controls
• One integrated, federated model supporting all aspects
• Tools have the capability to support these Engineering Management aspects
21Four tenets of Systems Engineering from a Model-Based perspective
Conclusion
• The richness of the information can and should be conveyed, assessed, acknowledged
• Exploit the richness as complexity of projects grow.
