The real life alchemists of the 21st century.
Process engineering relates to the improvement and execution of all processes. A process is best described as a structured set of actions to achieve a definite goal. Every process is designed to transform an input (raw materials) to an output (products and services). Engineering a process will specifically involve saving time and cost by optimising the design and training the people involved. Process engineering is related to all chemical, biological, mechanical and manufacturing processes. Process engineers use computer software to design and monitor the processes used across these engineering industries. While generally working behind a computer in an office, some engineers work on-site to monitor the actual outcome of their processes. Process engineers will not actively involve themselves in the process. For instance, if a process is obstructed by a malfunctioning tool, the process engineer will notify the technical worker involved to remedy the issue.
Graduates of process engineering obtain expert knowledge of process theory along with training in computer-aided technology. Process engineers are generally hired to work for large companies to monitor various processes. It is highly unlikely that a process engineer will have the ability to start their own business, although they may be able to contract their services. The majority of process engineers work in the chemical engineering industry.
