The typical activities that are performed in a process are called base practices. Consistently performing base practices contributes to achieving the desired outcomes and eventually the process purpose.
Base practices include detailed process activities (what should be done). Base practices consume inputs and produce outputs (work products).
Base practices are specific to capability level 1 and are directly aligned with ITIL best practices.
Base practices are changed for different processes, and generic practices are the same for all processes.
Generic practices are indicators of activities of generic type and provide guidance on the implementation of the attributes in levels 2 through 5.
