Service delivery, run as a system: what an IT Service Management System covers

In short, ISO/IEC 20000-1:2018 is the international standard behind an IT Service Management System. Specifically, it applies to any organisation that plans, delivers, operates, and improves IT services — whether for internal users or external customers — and, as a result, gives that delivery a structured, auditable framework rather than a set of informal habits.

Consequently, the standard covers the full service lifecycle: service design and transition, incident and problem management, change and configuration management, capacity and availability planning, and supplier management. Notably, this is closely aligned with widely used ITIL practice, but framed instead as auditable management system requirements rather than best-practice guidance alone.

Therefore, an effective IT Service Management System demonstrates that service levels, escalation paths, and continual improvement are not dependent on any one person's knowledge, but are instead built into how the organisation runs day to day. Additionally, you can read more about how this fits alongside our wider ISO certification services, and you can also view the full official standard documentation for technical reference.

Who relies on an IT Service Management System

Because dependable IT delivery underpins very different business models, an IT Service Management System applies broadly. However, it delivers the most value wherever service levels are contractual, complex, or business-critical. So, in practice, that spans the following sectors:

What an IT Service Management System changes on the ground

Once implemented, this kind of system tends to reshape day-to-day service delivery rather than just paperwork. For instance:

Our certification process for an IT Service Management System

Getting your IT Service Management System certified with IEMA follows a structured, EGAC-accredited audit pathway from application to certificate issuance, and beyond. Consequently, each stage builds on the last:

1. Application & contract review

   We scope your certification boundary — services, sites, and supplier relationships — and confirm audit duration and pricing.

2. Documentation review

   Your service management policy, service catalogue, and system documentation are reviewed against ISO/IEC 20000-1:2018.

3. Stage 1 audit

   An on-site readiness assessment confirming your system is implemented and prepared for the certification audit.

4. Stage 2 audit

   Full evaluation of implementation and effectiveness across incident, change, and capacity management.

5. Certification decision

   An independent technical committee reviews audit findings ahead of the certification decision.

6. Certificate issuance

   Your ISO/IEC 20000-1:2018 certificate is issued, valid for three years under the EGAC accreditation scope.

7. Surveillance & recertification

   Annual surveillance audits maintain certification; a recertification audit renews it at the three-year mark.

Meanwhile, for a broader look at how audits are structured across standards, see our certification approach, or, alternatively, explore our related testing services for infrastructure and systems verification.

Change and configuration control — a core audit focus area for this type of certification.

What your IT Service Management System needs in place

Above all, these form the baseline our auditors assess against during Stage 1 and Stage 2 of your audit:

• A documented service management policy and objectives
• A service catalogue and defined service level agreements
• Incident and problem management procedures
• Change and configuration management controls
• Capacity and availability management processes
• Supplier and third-party service management procedures
• Service reporting and customer satisfaction measurement
• Internal audit and management review records

Who audits your IT Service Management System

Accredited, independent, and Nigerian-based, IEMA Standards Ltd is accredited by the Egyptian Accreditation Council (EGAC), a full IAF/ILAC Multilateral Recognition Arrangement signatory — so, in practice, your certificate carries international standing rather than local-only recognition.

Headquartered at 27A Alternative Drive, Chevron, Lekki, Lagos, IEMA serves clients across Nigeria and, moreover, the wider African market.
