Systems Engineering

Drawing from the principles of systems science, systems engineering is an interdisciplinary field and methodology focused on the design, integration, and management of complex systems over their entire life cycles. It employs a structured, holistic approach to orchestrate the efforts of diverse technical disciplines, ensuring that all individual components and subsystems function together effectively to achieve the overall mission, satisfy stakeholder needs, and balance competing constraints such as cost, schedule, and performance.
