You can create your own process to define a specific way for a team to work. For example, a build manager for a team working on a GUI project creates a process called GUI Process. This process contains a custom purpose called Beta Test with a corresponding process rule called Beta Test. The process rule defines a new level of testing for the beta release. The new Beta Test process rule enables the build manager to perform builds to prepare for the beta test release, and it can only be found in the new process, GUI Process.
