USER REQUIREMENTS SPECIFICATION & HUMAN FACTORS ASSESSMENT (URSHA)
Document Status: Draft | Version: 1.0 | Effective Date: Current
1. INTRODUCTION & PURPOSE
This User Requirements Specification and Human Factors Assessment (URSHA) document defines all mandatory user requirements, operational standards, human factors engineering criteria and usability specifications for the design, development, implementation and validation of GE equipment and associated systems. All requirements outlined within this document are binding for all project stakeholders, engineering teams and third-party vendors. Compliance with these requirements ensures alignment with GE global quality standards, regulatory compliance frameworks and human-centric design principles.
2. DOCUMENT SCOPE & APPLICABILITY
2.1 Primary Scope
Covers all hardware, software, user interfaces, control systems and operational workflows associated with GE industrial and commercial equipment. Includes human factors analysis for operator interaction, error mitigation, workload assessment and usability validation.
2.2 Applicability
This specification applies to all GE business units, project implementations, engineering design cycles and end-user training programs. All revisions and amendments to this document shall be formally reviewed and approved by the GE Quality Assurance (QA) and Human Factors Engineering (HFE) teams.
3. NORMATIVE REFERENCES & COMPLIANCE
All requirements contained within this URSHA shall comply with the latest versions of the following standards and regulations:
• GE Global Engineering Standards (GES) - All Volumes
• ISO 9241 Ergonomics of human-system interaction (Full Series)
• IEC 62366 Medical device usability engineering - Application to medical devices
• ANSI B11.0 Machine Safety Standards
• Occupational Safety and Health Administration (OSHA) Guidelines
• GE Human Factors Engineering (HFE) Design Handbook
4. CORE USER REQUIREMENTS (MANDATORY)
4.1 Functional Requirements
✓ All equipment functions shall perform as specified under all operational conditions and environmental parameters
✓ User interface controls shall provide immediate, accurate feedback for all input actions
✓ System shall support role-based user access with appropriate permission levels
✓ All critical operations shall include redundant confirmation steps to prevent unintended actions
4.2 Usability & Human Factors Requirements
✓ All user interactions shall be intuitive, requiring minimal training for qualified operators
✓ Visual displays shall be legible under all ambient lighting conditions (50 - 10,000 lux)
✓ Physical controls shall be ergonomically positioned for natural hand/arm movement, no excessive force required
✓ Error messages shall be clear, specific and provide actionable corrective guidance
4.3 Safety Requirements
✓ All safety-critical functions shall have independent fail-safe mechanisms
✓ Emergency stop controls shall be prominent, accessible and unambiguous in all operational modes
✓ System shall automatically log all safety-related events and operator interventions
5. HUMAN FACTORS ASSESSMENT & VALIDATION CRITERIA
Human Factors Engineering (HFE) assessment is a mandatory validation activity for all GE equipment and systems. The assessment shall evaluate operator performance, cognitive workload, physical ergonomics, error potential and situational awareness. All identified human factors risks shall be classified by severity (Critical, High, Medium, Low) and mitigated with documented corrective actions. Validation shall include user testing with representative end-users, task performance metrics and post-test usability surveys. All HFE assessment results shall be formally documented and included in the final project validation package.
