Project management refers to "using professional knowledge, skills, tools and methods in project activities to make the project meet or exceed the needs and expectations of project stakeholders". Project stakeholders refer to those who participate in the project and are affected by the project activities, including project sponsors, project teams, helpers, customers, users and even project opponents. Knowledge domain refers to some important knowledge that the project manager must have. The five core knowledge areas of project management are: scope, time, cost, quality and resources. At present, the project management of enterprises still stays in the traditional isolated management mode. Project management itself may have some experience, but there is no good mechanism to make project management closely related to the company's operation management, so as to make it better connected. The relationship between project management and operation management has not been well utilized.
