翻译:The project manager, in the broadest sense of the term, is the most important person for the success or failure of a project. The project manager is responsible for planning, organizing and controlling the project. In turn, the project manager receives authority from the management of the organization to mobilize the necessary resources to complete a project. In general, the project manager’s authority must be clearly documented as well as defined, particularly in a matrix organization where the functional division managers often retain certain authority over the personnel temporarily assigned to a project. The following principles should be observed: The interface between the project manager and the functional division managers should be kept as simple as possible. The project manager must gain control over those elements of the project which may overlap with functional division managers. The project manager should encourage problem solving rather than role playing of team members drawn from various functional divisions.
