Two-minute brief

ISO 37500 guidance explained: video brief

A two-minute brief on ISO 37500, the international guidance on outsourcing, and why it is used for assessment rather than certification.

  • Two-minute brief
  • 2 min

Key takeaways

  • ISO 37500 is guidance on outsourcing; there is no ISO 37500 certificate.
  • It serves both outsourcing clients and service providers.
  • Four themes: mutual governance, flexibility, risk and collaborative relationships.
  • It covers the outsourcing life cycle from deciding what to outsource to exit.
  • Organisations use it through assessment and an improvement plan.

Guidance for clients and providers alike

ISO 37500 is the international guidance standard on outsourcing. It covers the main phases, processes and governance aspects of outsourcing, independent of the size of the organisation or its sector, and aims to give client and provider a sound foundation for entering into an arrangement and keeping it successful for the whole contractual period. Its four themes are governance for the mutual benefit of both parties, flexibility as requirements change, outsourcing risk and collaborative relationships. This short film walks through what it covers.

Because it contains guidance rather than requirements, there is no clause-by-clause audit and nothing to certify. Outsourcing governance is treated as a governance subject before it is a procurement one, which is why ISO 37500 sits alongside other governance, risk and resilience standards.

What the guidance addresses

The guidance addresses the outsourcing life cycle, the main phases of an arrangement, recognising that client and provider act separately in some phases and together in others; the processes that run through each phase, from deciding what to outsource to managing the arrangement until it ends; governance with decision rights, roles and escalation agreed by both parties; flexibility, so arrangements accommodate changing business requirements rather than locking in the needs of the day the contract was signed; the risks involved for both parties across the arrangement; and collaborative relationships.

Organisations use it through assessment. The arrangements, providers, entities and services in scope are agreed, the organisation's role as client, provider or both is confirmed, and strategy, contracts, governance and relationships are reviewed against the guidance, leading to a prioritised improvement plan. Leadership, internal audit and, where wanted, an independent reviewer judge the result. ISO 37500:2014 is the first edition, confirmed in 2021, and its use suits outsourcing clients, service providers and practitioners of any size or sector.

The guidance is written for both sides: a provider can use it to run its client accounts consistently, and a client to govern its providers, across IT, business process and facilities outsourcing alike.

ISO 37500: questions people ask

Is there an ISO 37500 certificate?

No. ISO 37500 is a guidance standard: it gives recommendations, not requirements, so no accredited body certifies against it. An organisation can show that its outsourcing governance has been assessed and strengthened against the guidance, and can certify to a related requirements standard such as ISO 9001, ISO/IEC 27001, ISO 22301, ISO/IEC 20000-1 or ISO 37301.

Is ISO 37500 for the client or the provider?

Both. ISO 37500 is written for outsourcing clients, providers and practitioners, and recognises that the parties act separately in some phases of the life cycle and together in others. A provider can use it to run its client accounts consistently; a client can use it to govern its providers.

Is ISO 37500 still current?

Yes. ISO 37500:2014 is the current edition; ISO confirmed it in 2021, and a further systematic review closed on 5 June 2026 without a revision shown on ISO's page so far.

Does ISO 37500 apply to IT, BPO and facilities outsourcing alike?

Yes. The guidance is independent of size and sector and covers any outsourcing relationship, first-time or repeat, with one provider or several. Each arrangement uses the same structure, tailored to its sector, the applicable law and its size.

What do you need to prepare an ISO 37500 proposal?

A list of the outsourcing arrangements in scope, whether you are the client, the provider or both, the entities and countries involved, the certificates you hold, who is asking for evidence and your deadline. That is enough for a scoped, all-inclusive proposal.
