Systems engineering is a methodical approach that applies principles, concepts, and management methods to enable the successful realization, use, and retirement of engineered systems. It employs a holistic perspective and systems thinking to integrate various disciplines into a cohesive effort. Systems engineering takes a life cycle approach, encompassing all phases from conception to disposal or retirement, aiming to identify, prioritize, and satisfy the needs of stakeholders. The overarching goal is to manage risk and deliver solutions that meet the intended purpose in real-world operation while minimizing unintended consequences.
