ISO/IEC 20000-1:2018
ISO 20000-1 Standard Implementation
ISO/IEC 20000-1 is the international standard for IT service management systems (SMS). It proves that your organisation delivers IT services in a controlled way — with defined SLA levels, and managed incidents, changes and capacity.
What is ISO/IEC 20000-1:2018?
ISO 20000-1 is the certifiable version of the ITSM best practices known from ITIL. While ITIL is a library of recommendations, ISO 20000-1 is a standard with clear requirements that an independent auditor checks — which is why tenders and corporate clients name it as a requirement for IT suppliers, data centres, MSPs and internal IT departments.
The standard covers the entire service lifecycle: from the catalogue and service-level agreements (SLAs), through day-to-day operations (incidents, requests, problems, changes), to budgeting, capacity and service continuity.
Implementation phases
The real phases we guide every project through — from preparation to the certificate, which comes only at the end:
Measurement, Audit and Improvement
The steps follow the standard's clauses, with a focus on the operational ITSM processes in clause 8. Not sure whether you already meet these requirements? Check with the short self-assessment at the bottom of this page.
Context, scope and leadership
We define which services fall within the SMS, who the customers are and their expectations; management adopts the service management policy.
Planning and support
SMS objectives, risks, team competence and documentation — including the service management plan.
Service portfolio and catalogue
We catalogue services, their components, supplier dependencies, and set up a catalogue available to customers.
SLAs and customer relationships
We define measurable service levels (availability, response time), reporting and regular reviews with customers.
Incidents, requests and problems
We organise service-desk processes: logging, prioritisation, escalation, resolution and root-cause analysis of recurring incidents.
Change and release management
Every change goes through a risk assessment, approval and a rollback plan — the end of 'cowboy' changes in production.
Capacity, availability and service continuity
Forward planning of resources and recovery plans for critical services.
Measurement, audit and improvement
KPI reports, the internal audit, management review and continual service improvement.
The path to certification
Certification follows the standard two-stage model.
The prerequisite for everything: the system is implemented and applied in practice — every requirement of the standard met, the internal audit carried out and the management review completed.
Checking the service catalogue, the SLA framework and process documentation.
Checking how the service desk operates and incident/change records in practice.
A certificate valid for 3 years.
Annual audits and recertification in the third year.
Benefits of Adopting the Standard
An increasingly common requirement in IT-service procurement, especially for the public sector and banks.
SLA metrics and processes reduce downtime and firefighting in the IT team.
Clear expectations, reporting and reviews build long-term trust.
Defined processes reduce dependence on individuals and chaotic priorities.
An illustrative, typical scenario we often hear from clients — it does not represent a specific, named client.
“The IT team was firefighting with no order to it — there was no service catalogue and no SLA, so every ‘urgent’ request was equally urgent. ISO/IEC 20000-1 forced us to define a service catalogue, SLA response times and an incident management process — the service desk now knows what is genuinely a priority.”

Related standards
ITIL provides the detailed practices used to meet ISO 20000-1's requirements — the standard and the library are a natural pair. ISO 27001 covers the security of the same services and is often certified alongside it, while ISO 22301 deepens the continuity of critical services.

FAQ about ISO/IEC 20000-1:2018
What's the difference between ISO 20000-1 and ITIL?
ITIL is a library of best practices with no organisational certification; ISO 20000-1 is the standard against which an organisation is certified. ITIL practices are the most common way of meeting the standard's requirements.
Who is ISO 20000-1 for?
IT companies, MSPs, data centres, software companies with support functions, and the internal IT departments of larger organisations.
How long does implementation take?
Usually 4 to 8 months, depending on the number of services and the maturity of existing ITSM processes and tools. For large systems — over 500 employees, multiple locations or an integrated system of several standards — a project realistically runs beyond a year; we handle those clients too.
Do we need an ITSM tool?
The standard doesn't prescribe a tool, but in practice a service-desk (ticketing) system is essential for evidence of incidents, requests and changes.
How much does ISO 20000-1 implementation cost?
There is no fixed price that applies to everyone — the cost depends on the organisation's field of activity, its size and number of employees, the chosen standard and the current state of the system. Send us a short description of your organisation and we will prepare a free, tailored estimate.
Standards that fit together like a honeycomb
Each standard keeps its own shape, but together they form a single solid, integrated management system (IMS) — with no gaps or overlaps. Click a hexagon to open that standard.
More about the integrated management system
An integrated management system (IMS) combines two or more ISO standards — for example ISO/IEC 20000-1 with ISO 9001 or ISO 14001 — into one shared framework of documentation, objectives and internal reviews, instead of each standard living in its own parallel procedure.
A single structure (the High-Level Structure — HLS) shared by every modern ISO standard. Thanks to it, the quality policy, risk management, internal audits and management review can be common to several standards at once.
Each standard on its own addresses one part of the business — quality, environment, safety, information. When an organisation introduces several of them, separate systems quickly duplicate the same documentation and the same auditors.
Less duplicated procedure work, simpler management, stronger process oversight, more efficient use of resources and easier preparation for a combined certification audit.
ISO/IEC 20000-1 can be implemented on its own or as part of an integrated system — the decision depends on how many standards you're targeting and whether you're introducing them at once or gradually.

The EU, the US and other markets
ISO/IEC 20000-1 is the same standard wherever you certify it — what differs is the designation, the accreditation behind the certificate and what your customers ask for.
In the European Union the standard is adopted with an EN prefix, and what your buyer in the Netherlands, Germany or France looks at is not the prefix but the accreditation behind the certificate: a body accredited by a signatory of the international recognition arrangement (Global Accreditation Cooperation, formerly IAF) is recognised in other markets too. What EU partners and EU regulation expect is on the page about the EU market.
For companies with customers in the United States — supplier audits, security questionnaires and how ISO sits alongside SOC 2 — see the page about the US market.
Wherever your customer is, we run the project remotely in English — over Teams, WhatsApp or Viber, with documentation and records in English — and on site when that is easier.
Montenegro and the region: MEST ISO/IEC 20000-1:2019
When people ask about a MEST ISO/IEC 20000-1:2019 certificate (or a ISO/IEC 20000-1:2018 certificate), they mean the confirmation issued by an independent accredited certification body to an organisation whose system complies with every requirement of this standard. Montenegro's national edition of the standard carries identical content to the international edition — the same requirements, the same clauses, just under a national designation — which is why both designations turn up in tenders for the same standard.
Why do the designations differ if it's the same standard?
Every member country of the European and international standardisation system adopts the same standard into its own national catalogue and adds a national prefix — in Montenegro, that's MEST. The content, structure, clauses and every requirement an auditor checks during certification remain completely identical regardless of which designation appears on the document. That's why a certificate issued under one designation fully covers the other — it isn't two standards, but one and the same, simply under two names.
Our core activity is standards implementation and rollout: we prepare your organisation so the certification audit goes without surprises, and we explain terms like "ISO/IEC 20000-1:2018 certification" and "MEST ISO/IEC 20000-1 certificate" because that's exactly how clients search for them. What certification, accreditation, IAF and surveillance audits involve — read the Certification / ISO Certificate page, and about tender designations on the ISO Standards in Tenders page.
Montenegro is where we work from: our consultants are based in Podgorica, Budva and Bijelo Polje, documentation and training come in Montenegrin or in English, and the certificate itself is issued by an independent accredited certification body — not by us. We work on site in Serbia, Bosnia and Herzegovina, Croatia, North Macedonia, Albania and Kosovo as well — more about what we do in Montenegro.
