Product design is a broad concept that leads to the design of new products through comprehensive production and the development of ideas, which is called product engineering. Design experts design many products by working on concepts and ideas. This process starts with the recognition of the problem and goes through the stages of ideation, design, simulation, and construction of prototypes; In the construction stages, it leads to the creation of the final product.

In the process of making a product, a set of processes including production engineering, production planning, capacity management, and other related subjects are involved, through which how to make a designed product is explained and its creation is managed.

The main activities of this field include feasibility studies, the design, and construction of equipment and machinery needed by different departments of the organization, performance monitoring, and finally their optimization.
