Project management may be seen as a set of processes and activities that are undertaken to achieve the project objectives.

Some of these processes may take place once (e.g., the initial creation of the project charter),

but many others overlap and occur several times throughout the project.

One example of this process overlap and multiple occurrences is a change in a requirement that impacts scope,

schedule, or budget and requires a change request. Several project management processes such as

the Control Scope process and the Perform Integrated Change Control process may involve a change request.

The Perform Integrated Change Control process occurs throughout the project for integrating change requests.

Although there is no stated definition on how to integrate the project processes,

it is clear that a project has a small chance of meeting its objective when the project manager fails to

integrate the project processes where they interact.
