What is Systems Engineering
Systems engineering is an interdisciplinary approach with the goal of achieving successful systems realize. Systems Engineering focuses on defining and documenting early-stage system requirements, developing a system design, and reviewing the system for compliance with the overall requirements: operation, time, test, creation, cost & planning, training & support and disposal. Systems Engineering integrates all disciplines and forms a structured development process from the concept through the production phase to the operating phase. Both the technical and economic aspects are considered to develop a system that meets user needs.

Systems engineering techniques are used in complex development projects.

It is needed, as it is more difficult to handle issues such as logistics and coordination in large, complex projects, which can lead to massive project execution problems.
The other point is that Systems Engineering is practiced especially where errors are expensive. Systems Engineering originally came from space travel, today it is also used to connect aircraft, telecommunications systems and much more. There are also standards, certifications, qualifications, and what not only everything. This gives Systems Engineering the (bad) reputation of being bureaucratic and producing a lot of paper. This is also necessary in some areas; but Systems Engineering can also be useful for small projects with little effort.

Key elements of systems engineering
The system interacts with its environment, which may include other systems, users, and the natural environment. The system elements that compose the system may include hardware, software, firmware, people, information, techniques, facilities, services, and other support elements.

A systems engineer is a person or role who supports this interdisciplinary approach. In particular, the systems engineer often serves to elicit and translate customer needs into specifications that can be realized by the system development team.

In order to help realize successful systems, the systems engineer supports a set of life cycle processes beginning early in conceptual design and continuing throughout the life cycle of the system through its manufacture, deployment, use and disposal. The systems engineer must analyze, specify, design, and verify the system to ensure that its functional, interface, performance, physical, and other quality characteristics, and cost are balanced to meet the needs of the system stakeholders.

A systems engineer helps ensure the elements of the system fit together to accomplish the objectives of the whole, and ultimately satisfy the needs of the customers and other stakeholders who will acquire and use the system.
