Mission-critical systems

Systems Engineering

Systems engineering is the discipline that keeps a complex system consistent as a whole — from conceptual need to a verified operational product.

It defines the system from operational and functional needs, allocates requirements to subsystems, equipment and suppliers, controls the interfaces between them, and closes the loop through verification and validation. We apply this across the full development cycle under ARP4754B / ED-79B, ISO/IEC/IEEE 15288, ECSS-E-ST-10C and equivalent program frameworks.

Requirements, architecture, safety and verification evidence — connected from concept through certification or entry into service.

Full-lifecycle systems engineering

Define, plan and run the development process scaled to criticality, program constraints and the applicable certification or customer baseline.

  • Civil aviation development assurance under ARP4754B / ED-79B
  • Cross-industry system life-cycle processes under ISO/IEC/IEEE 15288
  • Space system engineering under ECSS-E-ST-10C and related ECSS standards
  • Integration with safety assessment for FDAL / IDAL allocation

Development and certification planning

  • Lifecycle, gates and design reviews (SRR, PDR, CDR, TRR) with entry/exit criteria
  • Development, design assurance, V&V, qualification, safety and certification plans
  • Support through qualification campaigns, DDPs and permit-to-fly milestones
  • Process evaluations against ARP4754B and ARP4761A expectations

Requirements, architecture and design

  • Stakeholder needs, ConOps and operational scenarios
  • Requirements capture, derivation, allocation, validation and verification
  • Functional, logical and physical architecture with ICDs
  • Traceability and change-impact analysis
  • Verification strategy, compliance matrices and IVVQ campaign support
  • Supplier requirement cascade, design integration and design reviews

Models and simulation

  • Model-based systems engineering interfaces (see MBSE / MBSA)
  • Plant and control performance models before hardware is available
  • Closed-loop simulation of control and monitoring logic, including failure and safe states
