Sources for the IT management comparison

Research record

• public-material snapshot date: August 3, 2026;
• SAF version: 0.7.0;
• full-study languages: Russian source and complete English translation;
• status: non-normative comparison;
• unit of analysis: concepts, relationships, lifecycle, roles, measures, and joint use with SAF;
• scale: direct, partial, composite, absent, or not applicable, plus high, medium, or low confidence.

Sources were checked against official public pages. Paid, restricted, and license-limited materials were not reconstructed from secondary summaries.

RITM

• Official RITM site — current positioning as the Rational IT Methodology.
• What RITM is — principles, model elements, and management areas.
• RITM public library — open and evolving body of material.
• itSMF Russia — RITM body of knowledge — the earlier name and stated development directions.

RITM has no stated stable methodology release number. The portal build number is not interpreted as a content version.

ITIL and ITSM

• PeopleCert — ITIL Foundation (Version 5) — public description of concepts, the four dimensions, ITIL Value System, lifecycle, and practices.
• PeopleCert — ITIL Version 5 explained — staged release and continued parallel availability of ITIL 4.
• PeopleCert — ITIL Service (Version 5) — service relationships, service levels, resilience, and improvement.

ITSM has no single normative owner. The general characterization of the field is derived from the intersection of official ITIL, ISO/IEC 20000, and FitSM materials and is marked as analytical synthesis.

ISO/IEC 20000

• ISO — ISO/IEC 20000-1:2018 — current third edition, 2023 confirmation, and Amendment 1:2024.
• ISO/IEC JTC 1/SC 40 — Practical Guide — public overview of the standard's purpose.

The SAF page is not an interpretation of certification requirements and does not replace the licensed standard text.

FitSM

• FitSM — standard — purpose of lightweight ITSM and composition of the family.
• FitSM — downloads — current version 3.0 core documents and FitSM-6 materials.

COBIT

• ISACA — COBIT resources — public description of COBIT 2019, publications, and focus areas.
• ISACA — COBIT 2019 Governance & Management Objectives — purpose of the Core Model and 40 objectives.

Detailed COBIT tables, objectives, and diagrams are not reproduced.

IT4IT

• The Open Group — IT4IT Standard, Version 3.0.1 — current edition incorporating Technical Corrigendum 1 for the 3.0 line.
• The Open Group — IT4IT catalog.
• The Open Group — IT4IT overview.

The official reference architecture and supplied ArchiMate model are not copied.

SRE

• Google SRE — resources.
• Site Reliability Engineering.
• The Site Reliability Workbook.

The body of knowledge is treated as an evolving engineering practice, not a versioned conformity model.

DevOps

• DORA — capabilities and 2025 research — empirical capabilities and outcomes; DORA is not treated as a general DevOps metamodel.
• Google Cloud — DevOps — movement, speed, reliability, and shared ownership.
• Microsoft Learn — DevOps overview — planning, development, delivery, and operation.
• AWS — What is DevOps — culture, practices, tools, and lifecycle ownership.
• ISACA — COBIT Focus Area: DevOps — governance projection of DevOps.

Only recurring common ground is included in the conclusions. One vendor's position is not presented as a universal definition.

Limitations and update policy

• The RITM public library and the SRE, DORA, and DevOps bodies of material change without a shared release cycle, so a snapshot date is mandatory.
• ITIL Version 5 is being introduced in stages; new public materials may refine the terminology.
• ISO, COBIT, and IT4IT have licensing restrictions; this analysis uses only permitted public descriptions and paraphrase.
• Absence of a public concept does not prove its absence from restricted material or a particular implementation.
• Any source update requires rechecking the mapping type, confidence, and conclusions, not merely changing a version number.
