5. Approach for SE Workflow Use Cases
In a SysML model
Define the Use Case Context
Identify an initial set of SE Workflow Use Cases
Capture what System Engineers Do
Initial pass based on Foundational Material
Total 31 Use Cases Identified
Prioritize Use Cases
Elaborate Use Cases with Activities
Produce a Review Document for each Use Case
Solicit Experts to refine and improve
Iterate as required
Derive SysML Needs Requirements from results

12. Integration with other Roadmap Efforts
Integration with Roadmap Key Capabilities
Capabilities include (from Sandy’s & Roger’s INCOSE Paper):
Model Construction
Model Visualization
Model Analysis
Model Management
Model Exchange and Integration
Support for MBSE Collaboration and Workflow
Approach
Work with each of the Capability Leads
Identify the SE tasks/services required in each
Represent tasks as an activity in the model
Show in high-level activities where each is called
Integration with SE Concept Model (SECM) – Domain
Import Use Case into SECM Model
Show refinement to the To-Be requirements
Synchronize Concept Terms

13. Workflow Task Patterns
Workflow Pattern 1
Significance of Patterns
They become a template for creating other workflows
They capture repeatable, common steps
They become a focus for language and tool development
Use Case Pattern 1
This pattern is common across many specialty SE Workflow Use Cases
Some actions are Task Patterns
