Plan Schedule Management is the process of establishing the policies, procedures, and documentation for planning,

developing, managing, executing, and controlling the project schedule. The key benefit of this process

is that it provides guidance and direction on how the project schedule will be managed throughout the project.

This process is performed once or at predefined points in the project. The inputs, tools and techniques,

and outputs of the process are depicted in Figure 6.3. Figure 6.4 depicts the data flow diagram for the process.
