This document gives guidance on the integrated implementation of ISO/IEC 27001 and ISO/IEC 20000-1 for organizations intending to:

a) implement ISO/IEC27001 when ISO/IEC 20000-1 is already implemented, or vice versa;

b) implement both ISO/IEC27001 and ISO/IEC 20000-1 together; or

c) integrate existing management systems based on ISO/IEC27001 and ISO/IEC 20000-1.

This document focuses exclusively on the integrated implementation of an information security management system (ISMS) as specified in ISO/IEC 27001 and a service management system (SMS) as specified in ISO/IEC 20000-1.
