Abstract
The project manager is responsible for managing the project and to assure that the project is on schedule. The project manager himself is a valuable resource to the project and hence it should be properly utilized. Classical ways to determine the workload applied to the project manager included, (1) the duration and size of the project and/or, (2)past experiences. Often, the result of the estimation is human-dependent and biased. In this paper, we use the Management-pyramid model to show how the management workload is related to the communication line theory, and show a comprehensive and unbiased way to make a quick estimate on it.
