TSE ISO/IEC TR 20000-3

TSE ISO/IEC TR 20000-3. OFFICIAL SCOPE IS UNAVAILABLE. This technical report provides guidance on defining the scope of ISO/IEC 20000-1 and on judging whether particular services, units, and activities are applicable within that scope. Its main concern is the boundary of a service management system, which is essential in service-management standards because scope determines what is managed, assessed, and potentially included in conformity or implementation work.

Why scope definition matters

In general technical terms, a service-management scope separates the services an organisation delivers from the organisational units, locations, suppliers, and outsourced arrangements involved in delivery. That distinction helps a service provider identify what it directly controls and what is supported by external parties. A well-defined scope also brings clarity to service catalogue planning, process ownership, supplier relationships, and performance measurement.

Relationship to ISO/IEC 20000-1

ISO/IEC 20000-1 is the core requirements standard for a service management system; this report serves as explanatory guidance on how to approach its scope and applicability decisions. In organisations with multiple business lines, shared service centres, or complex supplier models, scope definition helps clarify which services are inside the management system and how supporting or externally delivered activities should be considered.

• Principles for setting service management boundaries
• Organisational and operational distinctions in applicability decisions
• Building a clear, traceable and auditable scope statement
• Relating internal processes to externally provided services

As a result, the document should be understood as a decision-support reference rather than a standalone requirements standard. It is especially useful for organisations that need to align service-management terminology, boundaries, and responsibility relationships before implementing or reviewing ISO/IEC 20000-1.
