Typically, the systems engineering specialist oversees and integrates these functional disciplines into a coherent engineering effort.
Systems engineering has two principal thrusts, system design and system integration.
System design translates operational requirements into a design able to meet those requirements. Systems engineering is conducted at three levels within FAA, typically by different but interrelated groups of people. Investment Analysis systems engineering focuses on a subset of the NAS, defining the best candidate solutions to specific mission needs. Implementation systems engineering is the province of Integrated Product Teams, who develop and deliver those solutions determined at the Investment Decision to be most suitable for satisfying mission need. The SEMP describes the entire FAA systems engineering process at all three levels, as well as the roles and responsibilities of Product Teams and agency line organizations.
