The capability levels of a process area are achieved through the application of generic practices or suitable alternatives to the processes associated with that process area.
Reaching capability level 1 for a process area is equivalent to saying that the processes associated with that process area are performed processes.
Reaching capability level 2 for a process area is equivalent to saying that there is a policy that indicates you will perform the process. There is a plan for performing it, resources are provided, responsibilities are assigned, training to perform it is provided, selected work products related to performing the process are controlled, and so on. In other words, a capability level 2 process can be planned and monitored just like any project or support activity.
