Discipline engineering encompasses all types of specialised engineering, from a professional engineer's review and stamping of drawings to the use of specialised equipment.
There are two schools of thought on how managers should monitor discipline engineering. The first school views all engineering functions as independent and subject to the project's overall technical scope. The second school considers discipline engineering to be the project engineer's responsibility. This project engineer oversees the discipline engineers, ensuring they are verified, integrated, and directed. The majority of projects, in general, follow the second school of thought. Thus provides an additional layer of security and reduces the risks associated with outsourcing.
