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 8/3/2019
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 Task Patterns → * * * * 8/3/2019
