Model-Based Systems Engineering (MBSE) uses models to describe and analyze system structure, behavior and interfaces. Engineering Lifecycle Management (ELM) organizes work products and processes across the lifecycle. They complement one another when models connect to requirements, changes and verification evidence.
Why this matters
Models help teams reason about complex systems; lifecycle practices help teams govern the evolution of those models and the decisions around them. Integration can reduce disconnected work when ownership and version context are clear.
A practical approach
- Decide which engineering questions are best answered by models and which by textual requirements or records.
A practical example
Define how model elements relate to requirements, decisions, tests and change requests.
What to keep in mind
Establish version and configuration rules so reviewers know which model state applies.
Frequently asked questions
Make review responsibilities explicit across systems, software, hardware and verification teams.
Use representative changes to validate that links and reports remain useful through the lifecycle.
