【国外标准】 Information technology -- Service management -- Part 3: Guidance on scope definition and applicability of ISO/IEC 20000-1

Useful for service providers, consultants and assessors. It includes practical guidance on scope definition, applicability and demonstration of conformity to the requirements in ISO/IEC 20000-1. Guidance on the different types of conformity assessment and assessment standards is included. Although the requirements in ISO/IEC 20000-1 do not change with organizational structure, technology or service, operating the processes in a particular service environment will result in specific skill, tool and information requirements. Service management processes can cross many organizational, legal and national boundaries as well as different time zones. Service providers can provide a range of services to several different types of customers, both internal and external. Service providers can also depend on a complex supply chain for the delivery of services. This dependency can make the agreement and application of scope a complex stage in the service provider's use of ISO/IEC 20000-1.
