Systems engineering is a multidisciplinary field that focuses on the design, development, and management of complex systems. It involves integrating various components, such as people, processes, technology, and resources, to achieve a specific goal or set of goals. Systems engineers use a holistic approach to analyze, optimize, and improve systems, considering both the technical and non-technical aspects of the system. This field is commonly applied in industries such as aerospace, defense, transportation, and healthcare to develop efficient and effective systems that meet the needs of users and stakeholders.
