# Requirements Flow-Down Skill ## Purpose The Requirements Flow-Down skill provides systematic capabilities for capturing, decomposing, and tracing requirements throughout the mechanical design process, ensuring design intent is properly communicated and verified. ## Capabilities - Stakeholder requirements elicitation - Functional requirements decomposition - Performance requirements specification - Design constraint identification - Requirements traceability matrix - Verification method assignment - Requirements change management - Code and standard flow-down ## Usage Guidelines ### Requirements Hierarchy #### Requirements Levels ``` Level 1: Stakeholder Requirements - What the customer/user needs - High-level, solution-independent - Source: Customer specifications, standards Level 2: System Requirements - What the system must do - Allocated from stakeholder requirements - Source: System engineering Level 3: Subsystem Requirements - What each subsystem must do - Allocated from system requirements - Source: Architecture trade studies Level 4: Component Requirements - What each component must do - Allocated from subsystem requirements - Source: Detailed design ``` #### Requirement Types | Type | Description | Example | |------|-------------|---------| | Functional | What the system does | "Shall lift 500 kg" | | Performance | How well it performs | "Lifting time < 30 sec" | | Interface | Connections to other systems | "Shall mate with Type A connector" | | Environ...
