Project management, as its name implies, is to manage projects. Because the goal of the project is different from other things, the means and methods of management are different, but there are similarities and overlaps.

The goal of the project is divided into three aspects: time, quality and cost, which affect each other. Due to the different requirements and rights of project stakeholders, different projects have different choices. According to the characteristics of the project, the management focus should also be adjusted accordingly.

According to the requirements of PMP, project management is divided into 9 main areas and 5 stages.
