In short

ISO 20000-1 certification in Thailand at a glance

In Thailand, ISO/IEC 20000-1 is asked for by buyers and schemes rather than required by law. The drivers below show where the pressure comes from.

Service providers selling to Thai banks and payment firms meet service management expectations through the regulator rather than through a named standard. The Bank of Thailand's FPG. 19/2560 expects service providers to hold certification according to international or generally accepted IT standards, and its payment notification, SorNorChor. 11/2561, covers service availability and a regular security audit of IT systems; neither cites ISO/IEC 20000-1. The certificate still gives managed service firms, BPOs and shared-service centres an independently audited way to show incident, change and service level discipline, and digital is one of the Eastern Economic Corridor's target clusters. Certification comes from an accredited certification body, and the National Standardization Council's recorded scopes do not list ISO/IEC 20000-1, so check each body's accreditation. Sterling's Manila office builds the service management system, often alongside an ISMS, with Effivity and Sterling Academy included in the engagement. Local questions are answered below.

The need

Who needs ISO 20000-1 in Thailand, and what happens without it

In Thailand the question rarely comes from a law. It comes from the buyer, the regulator or the partner that wants proof before it signs. These are the organisations that get asked.

  • IT service providers and managed service firmsBank customers expect service providers to follow recognised IT standards, and ISO/IEC 20000-1 evidences service management.
  • Technology suppliers to payment system providersThe payment security notification covers availability and security audit of IT systems those suppliers run.
  • BPO and shared-service centresOverseas customers use service management certification to compare vendors.
  • Digital-cluster investors in the Eastern Economic CorridorDigital is one of EECO's five target clusters.

Requirements

ISO 20000-1 requirements in Thailand

Strip away the vocabulary and ISO/IEC 20000-1 requires a company to prove six things about how it plans and delivers IT services.

Services are defined and agreedA service catalogue and service-level agreements state what you deliver and to what standard.
Management owns the service systemTop management sets the service management policy and objectives and provides the people and tools to meet them.
Changes and releases are controlledChanges, releases and deployments are assessed, approved and tracked so live services stay stable.
Incidents and problems are resolvedIncidents and requests are handled to agreed targets, and recurring problems are traced back to their cause.
Capacity, continuity and security are plannedCapacity, availability, continuity and information security are planned so agreed service commitments can be met.
Suppliers and performance are reviewedSuppliers and internal teams are managed against agreements, performance is reported, and the system is audited and reviewed.

In Thailand these six sit alongside the local laws and regulations listed under drivers below; one system can evidence both. The detail is on the global hub: ISO/IEC 20000-1 explained →

How Sterling gets a Thai company certified

How to get ISO 20000-1 certified in Thailand

One team from the Manila office carries the work from scoping to certificate. Clients across Thailand are served from Sterling's Manila office, on site where the work needs it and remotely otherwise.

  1. Discovery call and scopeEntities, locations, regulators and target date, agreed before any proposal.
  2. Gap assessment against ISO/IEC 20000-1 and the Thai requirements that apply to youControls you already run for your regulators and customers are reused, not rebuilt.
  3. Your system built with your team in EffivityRisks, controls, evidence, incidents and reviews in one live system the auditor can see.
  4. Internal audit, management review and corrective actionsYour internal auditors trained by Sterling; the evidence proven before the certification body arrives.
  5. Certification body stage 1 and stage 2, then surveillanceAn accredited body audits and decides. Sterling supports the audits and the three-year cycle.
Included in every engagement
  • End to end, from one team
  • Effivity ISO & GRC software
  • Preferential Sterling Academy access, with complimentary awareness training for your people
  • Internal auditor training for your audit team, as applicable to your standard
  • Vulnerability assessment on ISMS engagements

The Sterling Promise: 100% on-time completion, 100% success, 8,100+ client engagements.Sterling does not certify. Certification decisions stay with independent bodies.

Time

How long does ISO 20000-1 certification take in Thailand?

There is no standard duration: it depends on your scope and on how much of the system already runs. In Thailand these are the factors that set the timeline.

  • Maturity of incident, change and service level processes
  • Number of services and customers in scope
  • Tooling evidence available for the main audit

Sterling agrees a dated plan with you on the discovery call, once the scope is known.

Cost

How much does ISO 20000-1 certification cost in Thailand?

The cost has two parts: the consulting work to build and prove the system, and the certification body’s audit fees, which are quoted separately. In Thailand these factors move both.

  • Number of services, locations and customers
  • Process and tooling gaps to close
  • Certification body audit fees quoted separately from consulting

Sterling gives one customised, all-inclusive proposal after the discovery call, never before the scope is agreed.

Choosing a partner

ISO 20000-1 consultants and certification bodies in Thailand

Two different organisations are involved. A consultant helps you build the system and prove it works; an accredited certification body then audits or assesses it and decides. Keeping the two separate is what makes the result credible to buyers and regulators.

  • Check that the body’s accreditation or approval covers ISO 20000-1 and your sector, and that its certificates can be verified online.
  • Ask the consultant how the local requirements in Thailand are mapped into the same system, so nothing runs twice.
  • Ask for client references in your sector; Sterling’s client letters are available on request.
  • Agree who owns the evidence and the tool after the engagement; with Sterling the system stays yours, in Effivity.

    Laws and regulations that drive ISO 20000-1 in Thailand (2)

    InstrumentHow it treats the standard
    Bank of Thailand Notification No. FPG. 19/2560, Regulations on Information Technology Risk of Financial InstitutionsRelated
    Service providers expected to hold certification to international or generally accepted IT standards; no ISO number named.

    Accreditation, audit language and remote audits in Thailand

    Use a certification body accredited for ISO/IEC 20000-1 by a body within the international mutual recognition arrangements now run by Global ACI (Global Accreditation Cooperation Incorporated). The NSC scopes recorded for management systems do not list ISO/IEC 20000-1, so read the certification body's accreditation certificate. No body is named here. Edition and transition details: ISO/IEC 20000-1 hub →

    Audit language

    Audits can be in English or Thai; service catalogues and incident records are commonly in English for international clients.

    Remote and on-site

    Much of the audit can be remote where the certification body allows it, since service records are digital; operations centres and data sites are visited on site.

    ISO 20000-1 in Thailand: questions clients ask

    Is ISO 20000-1 required of IT suppliers to Thai banks?

    Not by name. The Bank of Thailand's IT risk notification expects service providers to hold certification according to international or generally accepted IT standards, without citing ISO/IEC 20000-1 or any other number. A bank may therefore accept it, or ask for something else, so confirm with each customer.

    Does the payment security notification mention service management?

    It covers service availability and a regular security audit of IT systems for payment system providers, and it names no ISO standard. ISO/IEC 20000-1 does not replace those requirements, but its incident, change and service level processes produce much of the availability evidence a regulator may want.

    Which accreditation should an ISO 20000-1 certification body hold?

    IT service management is not on the list of scopes recorded for the National Standardization Council, so a certification body's claim to cover ISO/IEC 20000-1 rests on its own accreditation. That should come from a body in the international mutual recognition arrangements and name the standard. Obtain the accreditation certificate and read it before you commit to an audit.

    Should ISO 20000-1 and ISO 27001 be combined?

    Often, yes. Both share the same management system structure, so a single integrated system, internal audit programme and management review can serve both, and many certification bodies can audit them together. Whether that suits you depends on your customers' demands and on the certification body's accreditation scope for each.
