In [[engineering]] and [[physics]], a physical system is the portion of the universe that is being studied (of which a [[thermodynamic system]] is one major example). Engineering also has the concept of a system referring to all of the parts and interactions between parts of a complex project. [[Systems engineering]] is the branch of engineering that studies how this type of system should be planned, designed, implemented, built, and maintained. Expected [[result]] is the behavior predicted by the specification, or another source, of the component or system under specified conditions.<ref name=":0" /> | In [[engineering]] and [[physics]], a physical system is the portion of the universe that is being studied (of which a [[thermodynamic system]] is one major example).
