Project Time Management includes the processes required to ensure timely completion of the project.
Figure 6-1 provides an overview of the following major processes:

	Activity Definition — identifying the specific activities that must be performed to produce the various project deliverables.
	Activity Sequencing — identifying and documenting interactivity dependencies.
	Activity Duration Estimating — estimating the number of work periods which will be needed to complete individual activities.
	Schedule Development — analyzing activity sequences, activity durations, and resource requirements to create the project schedule.
	Schedule Control — controlling changes to the project schedule.

  These processes interact with each other and with the processes in the other knowledge areas as well. Each process may involve effort from one or more individuals or groups of individuals based on the needs of the project. Each process generally occurs at least once in every project phase.
  Although the processes are presented here as discrete elements with well-defined interfaces, in practice they may overlap and interact in ways not detailed here. Process interactions are discussed in detail in Chapter 3, Project Management Processes.
  On some projects, especially smaller ones, activity sequencing, activity duration estimating, and schedule development are so tightly linked that they are viewed as a single process (e.g., they may be performed by a single individual over a relatively short period of time). They are presented here as distinct processes because the tools and techniques for each are different.
