Industrial engineers
The industrial engineers can plan, supervise, and manage the industry’s activities to ensure the economical, safe, and efficient use of materials, energy, and human resources. The job of these engineers includes how to control quality operations to discovering and dealing with concerns, which affect task management. They apply imaginations and experiences to create new manufacturing techniques in a variety of projects to reduce the consumption of materials, time or labour, and achieving timely goals. The engineer needs to oversee the communication between sales and production to meet the production needs.

In addition, an industrial engineer can consult with the finance department for more production resources and stocks. The application of accounting principles by the industrial engineers includes the use of trigonometry and other advanced mathematical topics to analyze, design and solve problems in their work. Industrial engineers are employed mainly in the manufacturing industry, professional, scientific, and technical industry and in the mining industry.

Chemical engineers
Since their role is to implement scientific principles in the manufacturing industry, chemical engineers need to develop good working relations with other employees involved in manufacturing processes. Moreover, chemical engineering will always venture into dynamic areas, for example, renewable power, and resource technology, and therefore support in maintaining the need for engineering services in manufacturing and industrial sectors.
