Manufacturing engineering is considered to be a subdiscipline of industrial engineering/systems engineering and has very strong overlaps with mechanical engineering.

Open systems have input and output flows, representing exchanges of matter, energy or information with their surroundings.

System

Group of interacting or interrelated elements that act according to a set of rules to form a unified whole.

Open systems have input and output flows, representing exchanges of matter, energy or information with their surroundings.

Important distinctions have also been made between hard systems – technical in nature and amenable to methods such as systems engineering, operations research, and quantitative systems analysis – and soft systems that involve people and organisations, commonly associated with concepts developed by Peter Checkland and Brian Wilson through Soft Systems Methodology (SSM) involving methods such as action research and emphasis of participatory designs.
