Systems Engineering

ATCorp systems engineering activities adapt the standard principles outlined by the International Council on System Engineering and other standards organizations to the requirements of our customer organizations.

Our systems engineering group has extensive experience with:

• Enterprise Architecture – Enterprise architecture is a rigorous description of the structure of an enterprise, its decomposition into subsystems, the relationships between the subsystems, the relationships with the external environment. ATCorp developed enterprise architectures for three terminal systems: Runway Status Lights, Low-cost Ground Surveillance System and the Terminal Automation Modernization and Replacement System. ATCorp engineers developed tools to facilitate timely and accurate development and editing of the Enterprise Architecture Products, enabling the human to focus on development of accurate, graphical representations of operations and systems and relegating to the computer the drudgery of producing large, complex matrices of detailed, abstract information.
  
  
• Safety Risk Management – Safety Risk Management provides a systematic and integrated method for managing safety of ATCorp and navigation services in the National Airspace System (NAS). ATCorp engineers have led development of FAA standard safety risk management products, such as Program Safety Plans, the Preliminary Hazard Analysis, and the Operational Safety Analysis.
  
  
• Requirements Analysis – ATCorp system engineers have led the development of procurement requirements for large-scale systems, performing, operational evaluation, functional decomposition, and performance analysis. We've led Subject Matter Expert reviews, retaining requirements genealogy and complex issues tracking.
  
  
• Risk Management – ATCorp has performed several risk management assignments for the FAA. These include design and oversight of a risk mitigation process for the Advanced Automation System that correctly predicted a processor performance problem early in its design cycle. We also conducted a safety risk assessment for the Final Approach Runway Occupancy Signal. That assessment augmented the FAA's standard risk management approach with a custom-designed state-transition diagram depicting the system states, both valid and invalid, and the likely outcome of each. The state-transition diagram was used to assess technical risk and develop risk mitigation strategies.
