Abstract: Automotive R&D is a complex system engineering process. In order to better manage automotive R&D projects and achieve project objectives more effectively, leading automotive companies typically exercise comprehensive control over their R&D projects, encompassing elements such as progress, quality, cost, scope, change, risk, and stakeholders. Progress directly determines the speed at which new products are launched, making it a critical factor in competition within the industry. Therefore, controlling progress is particularly important. The article introduces how to decompose the work items in the automotive development process, estimate the work item cycle, sort out logical relationships, draw network diagrams, and find ways to use critical paths to control project development progress, in order to optimize the automotive development cycle and improve resource utilization.

Key words: Network diagram; Critical path; Automotive research and development progress
