There is a famous saying in industry: Mould is the mother of industry, and IE is the father of industry. Mother gives you the foundation to grow, and father gives you the space to thrive. Therefore, I suggest that the government promote enterprises to introduce industrial engineering and guide enterprises to monitor the three functions and effects that IE must achieve. The first is performance management. The second function is called value engineering. What can be done to make it more valuable? Is there a better way to do it and can it take less time? I often say that the first is copying, the second is research, the third is innovation and the fourth is invention. The third function of IE is business management, including the allocation and evaluation of resources and the effective use of resources. What are the future resources? Time, talent, technology. The role of IE is to do more with limited resources. As far as time is concerned, high-order and critical human time is a resource; As far as talents are concerned, the key talents are resources; As far as technology is concerned, basic technology and innovative technology are resources. Time, talents and technology constitute the capital and source of our competitiveness. Together, they create five competitive products in the future, that is, speed, quality, engineering service, flexibility and cost. These five competitive products are all closely related to the role of IE.
