In the latest version of ITIL, there are no longer processes and functions. It has been replaced by practices.
The difference between processes and practices is quite subtle. While in ITIL V3, processes provided the workflows and activities, the functions were the various teams that made the process work. So to get the process to work, the functions were deployed to carry out the activities.
In ITIL 4, both the processes and functions are put together in a single bundle called as practices. Practices exist to take in pre-defined inputs and deliver outputs on expected lines. Both the workflow activities and the people to make it happen are a part of the practice – much like how DevOps works. There are no silos. All resources needed to create value are in the same box / silo.
While we had 26 processes and 5 functions in ITIL V3, ITIL 4 has 34 practices. It is categorized broadly into general practices, service management practices and technical management practices.
