ISO/IEC 20000-1:2018, the international standard for IT Service Management Systems, is not about what an organization says it does. It is about what it can demonstrate to an independent auditor with documented evidence, tested processes, and verifiable outcomes.
On 11 August 2026, TNV System Certification Pvt. Ltd. certified that Tranter IT Infrastructure Limited meets that standard.
What ISO/IEC 20000-1 Actually Requires
ISO/IEC 20000-1:2018 is an international standard published jointly by the International Organization for Standardization (ISO) and the International Electrotechnical Commission (IEC). It defines the requirements for an IT Service Management System referred to as an ITSMS and is the only international standard against which organizations can be independently certified for the way they design, deliver, manage, and continually improve IT services.
The standard is directly aligned with the principles of ITIL (Information Technology Infrastructure Library), the globally recognized framework for IT service management and is built on the understanding that delivering IT services well is not an instinct. It is a discipline that requires structured processes, clear accountability, formal agreements with clients, and a systematic approach to improvement.
ISO/IEC 20000-1:2018 certification requires an organization to demonstrate its ITSMS across six core service management areas:
| Service Design | Every IT service Tranter IT delivers is designed against agreed specifications — what it will do, how it will be measured, what support it includes, and what happens when something goes wrong. |
| Service Level Agreements | Formal, documented commitments to clients define exactly what standards Tranter IT is accountable for — response times, resolution targets, availability guarantees, and escalation paths. |
| Incident & Problem Management | When something fails, ISO 20000 requires a defined, documented process for responding, resolving, communicating, and identifying the root cause to prevent recurrence. |
| Change Management | Changes to IT systems and infrastructure follow a controlled, risk-assessed process — nothing is deployed in a client environment without proper authorisation and change control. |
| Supplier Management | Third-party vendors and technology partners who form part of Tranter IT’s service delivery are managed within the ITSMS — their performance contributes to the standard, not just Tranter IT’s own. |
| Continual Improvement | Service performance is reviewed regularly against agreed metrics. Gaps are identified, improvement actions are defined, and progress is tracked — this is a standing obligation, not an occasional exercise. |
To achieve certification, every one of these areas must be documented, implemented in practice, and independently audited by an accredited certification body. There is no shortcut and there is no self-certification. ISO 20000 is awarded by an auditor who has examined the evidence, not by an organization that has decided it deserves it.
Why This Standard Is Particularly Significant for Tranter IT’s Clients
ISO 20000 is perhaps the most directly operational certification an information technology organization can receive. This certification speaks specifically to how IT services are delivered — which is, at its most fundamental level, and what Tranter IT’s clients pay for.
This certification provides an independent validation of something that should have always been true of any IT partner: that service delivery follows a documented system, not individual judgment and that commitments are formal and measurable, not informal and assumed; and that when things go wrong — as they inevitably do in complex IT environments — there is a defined, tested process for making them right
In Nigeria’s technology services sector, where the gap between what companies promise and what clients actually experience can be significant, ISO 20000 certification places Tranter IT in a category of its own: an IT services company whose approach to service management has been assessed by an independent international body and found to meet the world’s recognized standard.
In the Words of Our Chief Executive
| “At Tranter IT, service delivery is not a department. It is the entire business. Every engineer we deploy, every support call we take, every infrastructure decision we make on a client’s behalf is an act of service. ISO 20000 certification means that the framework governing all of that has been independently audited and certified against the world’s recognized standard for IT service management. For our clients, particularly those in financial, manufacturing and government secotrs who depend on the reliability of their technology — this is not a certificate to display. It is a commitment we are now formally accountable for.” — Dr. Lare Ayoola, Chief Executive Officer, Tranter IT Infrastructure Limited |
With ISO 20000 certification now in place, Tranter IT’s clients can hold the company to a specific and demonstrable standard for IT service delivery. This means:
What Clients Should Expect
- Service Level Agreements are not informal understandings — they are formal, documented commitments that exist within a certified ITSMS and are measurable.
- Incidents are managed through a defined process — not ad hoc responses, with clear escalation paths, communication protocols, and resolution targets.
- Changes to client environments are controlled and authorized, not made without proper risk assessment and change management procedures.
- Problems are the underlying causes of recurring incidents and are investigated and addressed systematically, not ignored once the immediate issue is resolved.
- Service performance will be reviewed regularly against agreed metrics, and continual improvement is a standing obligation, not a periodic aspiration.
These are not promises. They are requirements of the standard Tranter IT has been certified against and their fulfilment is subject to ongoing surveillance by TNV System Certification Pvt. Ltd.
The Standard behind Three Decades of Service
Tranter IT has been delivering IT services in Nigeria since 1990. The relationships it holds with clients across banking, government, and the private sector were built long before ISO 20000 existed in its current form. The processes that underpin its service delivery were developed through three decades of real-world experience managing critical infrastructure in one of the world’s most complex and demanding technology environments and so when your IT Partner says they deliver — now there is international proof.
