Systems Engineering is an interdisciplinary field that focuses on the design, integration, and management of complex systems over their life cycles. It involves a holistic approach to ensure that all aspects of a project, from requirements to implementation, are considered and optimized for performance and efficiency. This discipline is crucial in various industries, including aerospace, defense, and information technology, where systems must work seamlessly together. The goal of Systems Engineering is to create a structured development process that enhances collaboration among different engineering disciplines. By employing methodologies such as Model-Based Systems Engineering and Systems Thinking, professionals can address challenges and ensure that systems meet user needs while remaining cost-effective and sustainable.
