As a key figure of the project team, the role and position of the project manager is important, and his influence on the success or failure of the project members and even the whole project is beyond doubt. The project manager is a very difficult role.

First of all, some relatively complex projects are often cross-disciplinary, cross-departmental and sometimes even cross-regional, which requires the project manager to have very rich professional knowledge to plan, organize, control and coordinate the work of the project team. But project managers are usually not and can't be experts in every field.

Secondly, most project members are temporarily transferred from functional departments in order to complete a specific project, with different backgrounds and qualifications, which greatly increases the difficulty of project manager management.

Therefore, as a project leader, the key to its successful management lies not only in how much professional knowledge or resources he has mastered, but also in his leadership level, and in how he organizes an efficient, stable and harmonious project team to ensure the success of the project.

Generally speaking, the leadership qualities of project managers can be divided into four categories, namely, the ability to know oneself, the ability to know the environment, the ability to manage oneself and the ability to influence others.
