A deficit in effective integration can lead to compromised performance, increased risks, and potential mission failure.

• Requirements Management and Allocation

  This facet involves defining, documenting, and managing the functional and performance requirements of the overall system. These requirements are then allocated to individual subsystems. Consider an aircraft’s flight control system; its requirements are derived from the overall aircraft performance specifications, and then allocated to the control surfaces, actuators, and sensors. Improper allocation can result in subsystems that are incompatible or incapable of meeting the overall system needs. Requirements need to be traceable throughout the design process to ensure compliance.

• Interface Management and Compatibility

  Managing the interfaces between different subsystems is crucial for ensuring seamless communication and operation. This includes defining communication protocols, data formats, and physical connections. For example, integrating a new radar system into an existing aircraft requires careful attention to the electrical, mechanical, and data interfaces to ensure compatibility and prevent interference. Incompatible systems or poorly defined interfaces can lead to malfunctions, data loss, or even system-wide failures.

• Testing, Verification, and Validation (TV&V)

  TV&V activities are essential for verifying that each subsystem meets its specified requirements and validating that the integrated system performs as intended. This involves conducting a series of tests at various levels of integration, from component-level testing to full-system testing.
