ITIL is a set of frameworks that is applicable across all the stages of the software development process. It is not just limited to a particular project within a company or SDLC process - it is like a superset that starts right from the organizational strategic phase until the Operations stage. For instance, any company can adopt the ITIL framework at the begining of forming the strategic building blocks.
As per the official ITIL site, the ITIL framework is divided into multiple intermediates and can be viewed from either a strategic perspective (called the Service Lifecycle) or implementation perspective (called the Service Capability). So, most of the SCM processes are covered in the ITIL Service Transition lifecycle module or the ITIL Release,Control and Validation (RCV) Capability module. Continuous delivery is covered under the ITIL Transition & Operations lifecycle module or the ITIL RCV & Operational Support and Analysis (OSA) Capability modules.
