Break down system specifications into detailed implementable requirements for individual device components and subsystems.
Subsystem | System ID | Subsystem ID | Description |
---|---|---|---|
Measurement Engine | SYS-001 | MEAS-001 | The measurement subsystem shall complete glucose analysis within 8 seconds of sample detection |
Measurement Engine | SYS-002 | MEAS-002 | The measurement subsystem shall provide glucose readings with coefficient of variation ≤5% |
Sample Interface | SYS-003 | SAMP-001 | The sample interface shall detect blood sample volume ≥0.5 μL within 2 seconds |
User Interface | SYS-004 | UI-001 | The display subsystem shall show glucose values in 14-point font minimum |
User Interface | SYS-005 | UI-002 | The display subsystem shall use red backlight for readings >180 mg/dL |
Data Management | SYS-006 | DATA-001 | The storage subsystem shall save readings with timestamp accurate to ±1 second |
Power Management | SYS-007 | PWR-001 | The power subsystem shall provide 3.3V ±5% to measurement circuits |
Risk ID | Risk Control Requirement ID | Subsystem | Description |
---|---|---|---|
RISK-003 | RC-001 | User Interface | The display subsystem shall show “ERROR” message when sample volume is insufficient |
RISK-005 | RC-002 | Measurement Engine | The measurement subsystem shall perform automatic calibration check before each reading |
RISK-007 | RC-003 | Data Management | The storage subsystem shall encrypt all patient data using AES-256 encryption |
RISK-009 | RC-004 | Power Management | The power subsystem shall display low battery warning when charge drops below 20% |
How detailed should subsystem requirements be?
How do I ensure all system requirements are covered by subsystem requirements?
What's the difference between regular subsystem requirements and risk control requirements?
How should I handle interface requirements between subsystems?
Can subsystem requirements be updated during development?
How do I write subsystem requirements for software components?
