PD ISO IEC TR 20000 — Information Technology Service Management Technical Report Series
Information Technology — Service Management — ISO/IEC TR 20000 Technical Report Series (2010–2016)
💻 PD ISO/IEC TR 20000 is the BSI technical report series adopting ISO/IEC Technical Reports under the title “Information technology — Service management”. ISO/IEC 20000 is the world-recognised standard for IT service management (SMS); its Part 1 (ISO/IEC 20000-1) sets the conformity requirements of a service management system and is certifiable, while the TR 20000 series provides guidance for understanding, implementing and integrating the standard. The six documents in this series — 20000-4 (process assessment model), 20000-5 (exemplar implementation plan), 20000-9 (guidance on application to cloud services), 20000-10 (concepts and terminology), 20000-11 (relationship with ITIL) and 20000-12 (relationship with CMMI-SVC) — form a complete support framework for establishing, implementing, assessing and improving a service management system. UK adoption was led by Subcommittee IST/60/2 (IT Service Management) of Technical Committee IST/60.
💡 ISO/IEC 20000-1 is the “certification yardstick”; the TR 20000 series is the “user manual and bridge”. It explains concepts, offers implementation exemplars, and answers the most-asked question — how ITIL, CMMI-SVC and ISO 20000 work together.
1. Scope and Composition of the Series 📌
Each part of the series supports the service management system from a different angle:
- 20000-4:2010 (Process assessment model): a process assessment model (PAM) for evaluating service management processes, supporting maturity assessment against ISO/IEC 20000-1.
- 20000-5:2013 (Exemplar implementation plan): an exemplar implementation plan from current-state analysis to certification, with milestones, document lists and frequent issues.
- 20000-9:2015 (Cloud service guidance): how to apply ISO/IEC 20000-1 to the delivery and management of cloud services (SaaS, PaaS, IaaS).
- 20000-10:2015 (Concepts and terminology): systematically explains key concepts (service, SMS, integrated process approach, governance and compliance) and terminology; the basic reading for the whole 20000 family.
- 20000-11:2015 (Relationship with ITIL): clarifies the mapping and complementarity between ISO/IEC 20000-1 and ITIL.
- 20000-12:2016 (Relationship with CMMI-SVC): clarifies the relationship between ISO/IEC 20000-1 and CMMI-SVC, linking process improvement and conformance certification.
⚠️ Parts 20000-4, -5 and -9 are based on scanned copies; descriptions of those parts in this article are written from publicly available domain knowledge. For the full assessment model, exemplars and guidance, confirm the current official BSI edition.
2. Technical Essentials of the Parts 🔧

| TR 20000-9 | Cloud service guidance | Applying SMS to cloud service delivery and management, responsibility allocation |
| TR 20000-10 | Concepts and terminology | What an SMS is, integrated process approach, governance and compliance, glossary |
| TR 20000-11 | Relationship with ITIL | Mapping and complementary use of ISO 20000-1 and ITIL |
| TR 20000-12 | Relationship with CMMI-SVC | Mapping and process-improvement linkage of ISO 20000-1 and CMMI-SVC |
3. Key Technical Requirements 🔥
Although technical reports, the requirement-oriented content is essential to implementing a service management system:
- What an SMS is (20000-10): the SMS is the framework by which an organisation establishes, implements, maintains and continually improves services, using an “integrated process approach” that treats service delivery, relationship, resolution, control and release processes as an interconnected whole.
- Process assessment (20000-4): a process assessment model evaluates the maturity of service management processes, giving organisations a structured way to identify weak processes and plan improvements.
- Implementation route (20000-5): an exemplar covering gap analysis, scope definition, documentation, process deployment and certification review, with clear responsibilities and milestones per stage.
- Framework integration (20000-11/-12): ISO 20000-1 defines “what to satisfy”, ITIL provides “how-to” practices, and CMMI-SVC provides the process and capability maturity improvement path — three complementary layers.
✅ They complement rather than replace each other: use ISO/IEC 20000-1 as the certification baseline, ITIL as the operational practice library, and CMMI-SVC as the engine for continual process maturity improvement — the mainstream combination for modern service organisations.
4. Engineering Practice and Application 🛠️
- 🔍 Building an SMS: use 20000-10 to align concepts and terminology as the baseline for team training and documentation.
- 🔧 Certification preparation: follow the exemplar implementation plan in 20000-5 to build a roadmap and checklist from gap analysis to certification.
- 📊 Process improvement: use the 20000-4 process assessment model for internal assessment, quantifying process maturity and driving continual improvement.
- 📋 Framework synergy: in organisations already using ITIL or CMMI-SVC, use the 20000-11/-12 mapping tables to align with ISO 20000-1 requirements quickly and avoid duplicate effort.
5. Frequently Asked Questions ❓
❓ Q: What is the relationship between ISO/IEC 20000-1 and the TR 20000 series?
A: ISO/IEC 20000-1 is the normative, certifiable standard defining SMS conformity requirements; the TR 20000 series are technical reports providing guidance for understanding, implementing, assessing and integrating the standard — they are not themselves certification requirements.

❓ Q: Can ITIL replace ISO 20000-1 or vice versa?
A: No. ISO 20000-1 is the certification requirement (“what”), ITIL is the best-practice library (“how”). TR 20000-11 sets out the mapping: build the system to ISO 20000-1 and implement processes with ITIL practices; the two complement each other.

❓ Q: Can cloud service delivery be managed under ISO 20000-1?
A: Yes. TR 20000-9 gives guidance for applying ISO 20000-1 to cloud services (SaaS/PaaS/IaaS), focusing on responsibility allocation between provider and customer, service-level management and integration of cloud environments.

🔍 Q: What is the use of process assessment?
A: The TR 20000-4 process assessment model evaluates service management processes by maturity level, helping organisations identify weaknesses, quantify improvement, and provide process-level evidence to senior management and certification bodies.
