Define Activities is the process of identifying and documenting the specific actions
to be performed to produce the project deliverables.
The key benefit of this process is that it decomposes work packages into schedule activities that provide a basis for estimating,
scheduling, executing, monitoring, and controlling the project work.
This process is performed throughout the project.
The inputs, tools and techniques, and outputs of this process are depicted
in Figure 6.5. Figure 6.6 depicts the data flow diagram of the process.
