Approach for SE Workflow Use Cases • In a Sys. ML 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 Sys. ML Needs Requirements from results 11/4/2020 5

Workflow Use Cases organized by Life Cycle Phases – Exploratory/Concept Stage – System Development Stage – Management Use Cases – SE Domain Use Cases – Verification and Validation Use Cases – Production Stage – Product and Service Life Management • Utilization Stage • Support Stage • Retirement Stage 11/4/2020 6

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 11/4/2020 12

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 → 11/4/2020 * 13
