Two Standards, One Goal
If you work in quality management and your organisation uses translation services, you may have come across ISO 17100 and wondered how it relates to the ISO 9001 quality management system you already know. On the surface they look similar. Both are ISO standards. Both use documented processes, competence requirements, and continual improvement language. But they serve very different purposes, and understanding how they fit together matters whether you are a quality manager procuring translation services, an auditor assessing a language service provider, or a consultant helping a client decide which standard to pursue.

ISO 9001 is a generic quality management system standard. It applies to any organisation in any sector and focuses on how a business manages its processes to consistently deliver products and services that meet customer and regulatory requirements. ISO 17100, by contrast, is a sector specific standard written exclusively for translation service providers. It defines the workflow, competence requirements, and quality controls that must be in place for a translation service to be considered conformant.
This article compares the two standards directly, explains where they overlap, where they diverge, and how they can work alongside each other in practice.
What ISO 9001 Requires at Its Core
ISO 9001:2015 is built on the High Level Structure used across modern ISO management system standards. It covers context of the organisation, leadership, planning, support, operations, performance evaluation, and improvement. The standard does not tell you how to do your work. It tells you to define your processes, manage them effectively, monitor performance, and keep improving.
For a translation company, ISO 9001 would require things like:
- Understanding who your customers and interested parties are
- Defining the scope of your quality management system
- Setting quality objectives and tracking them
- Managing the competence of your people
- Controlling externally provided services, such as freelance translators
- Monitoring customer satisfaction
- Running internal audits and management reviews
- Responding to nonconformities with corrective action
What ISO 9001 does not do is tell a translation company which specific steps must occur during a translation project, what qualifications a translator must hold, or how the revision process must be structured. That level of sector specific detail is outside the scope of a generic management system standard.
Exemplar Global Recognised Training ProviderRTP No. 310970What ISO 17100 Adds That ISO 9001 Does Not Cover
ISO 17100:2015, and its 2017 amendment, goes where ISO 9001 deliberately stops. It defines the specific requirements for translation services, including the mandatory workflow, the competence pathways for each role, and the post production obligations around feedback and archiving.
The standard requires a mandatory four stage production workflow: translation, check, revision, and verification. Revision must be performed by a second qualified person, not the original translator. This is not optional. It is a normative requirement. An organisation that skips revision and calls it ISO 17100 conformant is simply wrong.
ISO 17100 also specifies exactly what qualifications a translator must hold. There are three recognised pathways: a recognised degree in translation, a degree in another field combined with two years of documented professional experience, or five years of professional translation experience without a formal qualification. These pathways were clarified in the 2017 amendment and remain in force today.
Beyond the translator, ISO 17100 sets competence requirements for revisers, reviewers, and project managers. Each role has defined responsibilities that must be documented and verified. This is far more prescriptive than anything ISO 9001 requires.
Other ISO 17100 specific requirements include:
- Pre production processes covering enquiries, quotations, and client agreements
- Source file and reference material management
- Post production feedback mechanisms
- Archiving of project files and records
- Data protection obligations for client materials
None of these appear in ISO 9001 because they are specific to the translation sector. ISO 9001 would simply require you to control your operational processes, but it would not define what those processes must look like.
Where the Two Standards Overlap
Despite their differences, ISO 17100 and ISO 9001 share significant common ground. Both standards require:
- Documented processes and procedures
- Competence management for people performing work
- Control of externally provided services
- Customer communication and satisfaction monitoring
- Nonconformity management and corrective action
- Internal audits and management review
- Continual improvement
This overlap is not accidental. ISO 17100 was designed to complement ISO 9001, not replace it. The translation standard handles the technical and process specific requirements of the sector. ISO 9001 handles the broader management system framework that surrounds those processes.
For a translation company that holds both certifications, there is genuine efficiency to be gained. The quality policy, quality objectives, document control system, internal audit programme, and management review process can all serve both standards simultaneously. You do not need two separate management systems. You need one system that satisfies both sets of requirements.
This is a familiar concept for anyone who has worked with integrated management systems combining ISO 9001, ISO 14001, and ISO 45001. The same logic applies here. The High Level Structure of ISO 9001 provides the management system backbone, and ISO 17100 adds the sector specific technical layer on top.
Can a Translation Company Hold ISO 9001 Without ISO 17100?
Yes, and many do. ISO 9001 certification tells the market that a translation provider has a documented quality management system that has been independently verified. That is a meaningful signal, but it does not guarantee anything about the specific translation workflow, translator qualifications, or revision practices.
A company with ISO 9001 certification could theoretically have no mandatory revision step, use translators with no formal qualifications, and still maintain conformance with ISO 9001 as long as their processes are defined and followed consistently. ISO 9001 does not care what your process is, only that you have one and manage it effectively.
ISO 17100, on the other hand, cares very much what your process is. It mandates specific steps and specific competence levels. This is why clients in sensitive industries, legal services, medical translation, and government procurement often require ISO 17100 specifically rather than accepting ISO 9001 alone.
Can a Translation Company Hold ISO 17100 Without ISO 9001?
Yes, this is also possible. ISO 17100 contains enough management system requirements that a translation company can achieve certification to it without separately pursuing ISO 9001. ISO 17100 includes its own requirements around documented information, competence, customer communication, nonconformity management, and improvement.
However, ISO 17100 is less comprehensive than ISO 9001 on the management system side. It does not include the same depth of requirements around context of the organisation, risk based thinking, or the structured planning cycle that ISO 9001 demands. An organisation certified only to ISO 17100 may have gaps in its broader quality management framework.
For most translation companies, the practical advice is this: if you want to demonstrate sector specific translation quality, pursue ISO 17100. If you want a robust management system that also satisfies broader tender and procurement requirements, add ISO 9001. If you want both, build an integrated system that satisfies both standards simultaneously.
How an Auditor Approaches ISO 17100 vs ISO 9001
If you are an auditor conducting a certification audit against ISO 17100, your approach will be noticeably different from a typical ISO 9001 audit. The sector specific requirements demand that you understand the translation workflow well enough to verify it.
You will need to verify that:
- Each production project followed the mandatory workflow stages
- Revision was genuinely performed by a second qualified person, not the same translator
- Translator qualifications meet one of the three recognised pathways
- Project manager records demonstrate the required competence and responsibilities
- Pre production agreements with clients were documented
- Post production feedback and archiving processes are in place
This is process audit territory. You are following the translation project from enquiry through to delivery and checking that each mandatory step occurred and is evidenced. It is similar in approach to auditing a manufacturing process against a product standard, where you trace the product through each required stage and verify the controls at each point.
When auditing against ISO 9001 in a translation company, your focus shifts to the management system level. You are checking whether the organisation understands its context, manages risks and opportunities, sets meaningful quality objectives, and drives continual improvement. The specific translation workflow would be audited as an operational process under Clause 8, but you would not be prescribing what that workflow must look like.
For auditors who regularly work across multiple standards, this distinction between prescriptive sector standards and generic management system standards is a familiar one. ISO 22000 for food safety, ISO 13485 for medical devices, and ISO 17025 for laboratories all follow the same pattern: a sector specific standard that defines what the process must look like, sitting alongside or integrated with a broader management system framework.
If you want to understand how auditors approach sector specific standards in practice, the companion article on what ISO 17100 actually requires covers the standard clause by clause and is worth reading alongside this comparison.
Practical Scenarios Where Both Standards Apply
Scenario 1: A Translation Agency Tendering for Government Work
A mid sized translation agency wants to win contracts with federal government departments. The tender requires evidence of a quality management system and may specifically request ISO 17100 for translation services. The agency holds ISO 9001 but not ISO 17100.
In this situation, ISO 9001 alone may not satisfy the tender requirement if ISO 17100 is specifically requested. The agency would need to pursue ISO 17100 certification, which means implementing the mandatory workflow, documenting translator qualifications, and establishing the revision process if it does not already exist. The good news is that most of the management system infrastructure already exists under ISO 9001 and can be extended to cover ISO 17100 requirements without building a second system from scratch.
Scenario 2: A Quality Manager Procuring Translation Services
A quality manager in a pharmaceutical company needs to procure translation services for regulatory submissions. She is evaluating two suppliers. One holds ISO 9001 certification. The other holds both ISO 9001 and ISO 17100 certification.
For regulatory submissions, accuracy and process rigour matter enormously. The supplier holding ISO 17100 has demonstrated conformance with the mandatory revision requirement and has verified translator qualifications. This is directly relevant to the risk profile of the procurement decision. ISO 9001 alone tells her the supplier has a quality system. ISO 17100 tells her the supplier's translation process meets a defined sector standard. For high stakes regulatory content, ISO 17100 is the more relevant credential.
This is exactly the kind of supplier evaluation consideration that sits under ISO 9001 Clause 8.4 on managing externally provided processes and suppliers. Understanding what certifications mean in context is part of making informed supplier decisions.
Scenario 3: An Internal Auditor Reviewing a Translation Supplier
An internal auditor at a large organisation is conducting a second party audit of a translation supplier. The supplier claims ISO 17100 conformance but is not yet certified. The auditor needs to verify whether the supplier's processes genuinely meet the standard's requirements.
The auditor would need to sample completed translation projects and verify the workflow. Were all four production stages documented? Was revision performed by a different person from the translator? Can the supplier produce evidence of translator qualifications? Are client agreements documented before work commences?
This kind of second party audit requires the auditor to understand ISO 17100 specifically, not just ISO 9001. Generic quality management system auditing skills are necessary but not sufficient. Sector specific knowledge matters here, which is a principle that applies across many industries where technical standards sit alongside generic management system standards.
Building an Integrated System That Satisfies Both
For a translation company pursuing both certifications, the most efficient approach is to build a single integrated management system that satisfies both ISO 9001 and ISO 17100 requirements simultaneously.
The ISO 9001 elements that translate directly include:
- Context of the organisation and interested parties analysis
- Quality policy and quality objectives
- Document and record control
- Competence management framework
- Internal audit programme
- Management review process
- Nonconformity and corrective action process
The ISO 17100 elements that need to be added or specified in more detail include:
- The mandatory production workflow with all four stages defined
- Translator, reviser, reviewer, and project manager competence records and verification
- Pre production process documentation including client agreements
- Post production feedback, archiving, and data protection procedures
A well designed integrated system avoids duplication. The document control procedure serves both standards. The competence matrix covers all roles required by both standards. The internal audit programme checks conformance against both simultaneously.
For quality managers and consultants who are familiar with building integrated systems for ISO 9001, ISO 14001, and ISO 45001, the approach is conceptually the same. The skills transfer directly.
If you are building audit competence across multiple standards, understanding how sector specific standards relate to generic management system standards is a core skill. The comparison of ISO 9001, ISO 14001, and ISO 45001 covers the same principle in the context of the three most widely held management system standards in Australia.
Exemplar Global Recognised Training ProviderRTP No. 310970Key Differences Summarised
To bring this comparison together clearly:
- Scope: ISO 9001 applies to any organisation in any sector. ISO 17100 applies only to translation service providers.
- Process prescription: ISO 9001 does not define what your processes must look like. ISO 17100 mandates a specific four stage production workflow.
- Competence requirements: ISO 9001 requires you to determine the competence needed and verify it. ISO 17100 defines specific qualifications for each role in the translation process.
- Revision requirement: ISO 9001 has no equivalent requirement. ISO 17100 mandates revision by a second qualified person as a non negotiable step.
- Relationship: The two standards are complementary. ISO 17100 is designed to work alongside ISO 9001, not replace it.
- Market signal: ISO 9001 signals a quality management system. ISO 17100 signals that the translation process specifically meets a defined sector standard.
Why This Matters for Auditors and Quality Professionals
Understanding the relationship between generic management system standards and sector specific standards is a genuinely useful skill for auditors and quality managers. The pattern repeats across many industries. ISO 9001 provides the management system framework. A sector specific standard adds the technical requirements that ISO 9001 deliberately leaves open.
For auditors, this means recognising when sector specific knowledge is required and building it. For quality managers, it means understanding what each certification actually demonstrates when evaluating suppliers or deciding which standard to pursue. For consultants, it means being able to design integrated systems that satisfy multiple standards without creating unnecessary duplication.
ISO 17100 is a relatively niche standard in the broader ISO landscape, but the principles it illustrates are universal. If you are developing your auditing skills across multiple standards and want to understand how to approach sector specific requirements alongside generic management system requirements, solid foundational training in ISO 9001 auditing is the right starting point.
