Which part of ITIL provides guidance in adapting good practice for specific business environments and organizational strategies?

The ITIL Complementary Guidance is specifically designed to extend core ITIL publications by offering tailored guidance for particular industries, sectors, and organizational strategies. It bridges the gap between generic best practice and real-world application, making ITIL adaptable to diverse business contexts.

Service Support is a legacy ITIL v2 publication focused on operational processes such as incident and problem management, not on adapting ITIL to specific business environments.

Pocket Guides are condensed quick-reference materials intended for study and review, not authoritative guidance for contextual ITIL adaptation.

The Service Strategy book provides guidance on aligning IT strategy with business goals, but it is a core ITIL publication rather than the source of environment-specific adaptation guidance.
