ITIL is the most adopted ITSM framework. ITIL 4 reframes the practice around the Service Value System and Value Streams; the older Service Lifecycle stages remain useful vocabulary.

Mentor’s tip: ITIL 4 thinks in value streams and practices, not silos. Seven guiding principles + four dimensions + Service Value System. Use the legacy lifecycle vocabulary where it helps; do not let it freeze the architecture.
