Systems Integration

Whether embarking on a new transport scheme or keeping programs on track, Systems Integration (SI) is needed to manage the vast amount of information, the coordination of systems and the stakeholders involved in every effort.

At the beginning of each program, our practitioners partner to build a solid foundation—determine output capability, develop a governance structure to manage the program throughout the SI:D3 process, create a roadmap to success and forge alignment around the strategic plan.



With a plan of action in place, our team then creates a holistic perspective of the system, to inform the process of defining the system—its operations, requirements, scope and design.


Building on the first two tiers within the framework, the effort now focuses on applying robust Systems Engineering (SE) techniques and leveraging the established management process to deliver the desired outcomes.
