An example
This could be your situation.
Take one company as an example: three sites, three spreadsheets, no shared answer.
Nobody can consolidate.
Nordhavn Industries, 2,400 people in Hamburg, Lyon and Porto. A client asks where the group stands. Each site answers in its own spreadsheet, with its own scales.
Three weeks, a single base.
One ISO 20400:2017 assessment launched across all three sites at once, from the managers’ interview notes. The framework was already written, its 10 themes and levels L1 to L5 too.
Two costs avoided before being committed.
A score of 53 out of 100, with the gap concentrated on three themes. The AI companion spotted that two actions duplicated those of another audit. The committee report took one sentence to request.
What it saved them
- 3sites measured on the same base, instead of three questionnaires to reconcile
- 2duplicate actions caught before the spend
- 1committee report, with no manual rework
These figures are an example. They could be yours.
The standard imposes processes. Datamensio says where you stand.
01
The framework is already written
Themes, questions and levels L1 to L5, all written. You do not start from an empty spreadsheet.
02
The score lands the same day
Online, by self-assessment link or in interview. Theme by theme, comparable over time.
03
The gap becomes a costed plan
Every step up carries its action. The AI prioritises on expected effect, not on the order of the standard.
04
Progress can be demonstrated
Campaign after campaign, against your target and against your own past. That is what your board asks for.
The maturity scale
One level, the next, and the action that links the two.
This mechanism (a level, the level above, and the action that connects the two) is what turns an observation into a trajectory.
Do sustainability criteria genuinely weigh in award decisions?
- N1
No sustainability criteria in tenders. Award decisions rest on price, quality and lead time.
- N2
Criteria appear in some tender files, with a weighting that is low or varies by buyer.
- N3
A minimum weighting is defined and applied to priority categories. Deviations are justified.
- N4
Weighting is differentiated by category according to identified issues, evaluations are tracked and award decisions documented.
- N5
Weighting is reviewed periodically based on results obtained and supplier feedback, with a documented record of revisions.
Action to move from N2 to N3
Set a minimum weighting for sustainability criteria on priority categories, embed it in the standard tender template and check it at the award committee.

What this framework covers
ISO 20400 extends ISO 26000 into a specific territory: the procurement function. It describes how an organisation embeds social responsibility into its procurement policy, its organisation, its procurement process and its supplier relationships. It covers accountability, due diligence, respect for human rights and working conditions, environmental impacts across the life cycle, and the setting of priorities according to the actual issues within each purchasing category. It sets out guidelines, not enforceable requirements.
In practice, the procurement function is hard to steer on this topic because the evidence is scattered across the procurement department, the requesting business units, CSR and the suppliers themselves. The practical questions always come back to the same ones: do sustainability criteria genuinely weigh in the award decision, or do they merely appear in the tender file without influencing it? Does due diligence cover tiers beyond the direct supplier? Do buyers have methods they can actually use on their categories, or a general charter they sign without applying?
One confusion is worth clearing up: ISO 20400 cannot be certified, and no body issues an ISO 20400 attestation. External assessments exist, and sector labels too, but they rely on other grids. The regulatory context has, in any case, shifted the subject: due diligence duties and sustainability reporting obligations now require organisations to document the diligence carried out across the value chain. The standard’s guidelines then become a useful structure for organising that diligence, provided the organisation knows where it stands.
A maturity assessment asks a different question from a compliance check. A compliance check asks whether the requirement is met. An assessment asks what level of control the practice has reached, what distinguishes it from the level above, and what specific action gets it there. On a subject where almost everyone has a policy and few things are genuinely resourced, that distinction changes the conversation with the executive committee and with business units.
In Datamensio, the framework is ready to use and adaptable. The AI adjusts the themes, rephrases the questions to match your purchasing categories and refines the levels, or builds a variant from your procurement policy and internal documents. Assessments carried out across several entities can be compared with one another and consolidated into a single cross-organisation roadmap.
Reference standard: ISO 20400:2017
The themes assessed
Policy and accountability
Existence of a sustainable procurement policy validated at the right level, alignment with strategy and organisational commitments, accountability, transparency of decisions.
Governance and organisation of the function
Roles and responsibilities, reporting line of the procurement function, resources allocated, involvement of requesting business units, trade off between cost and sustainability.
Issue identification and prioritisation
Analysis of issues by purchasing category, mapping of social and environmental impacts, ranking of the families to be addressed as a priority.
Due diligence and human rights
Due diligence measures, coverage of tiers beyond the direct supplier, forced labour and child labour, working conditions, alert and remediation mechanisms.
Integration into the procurement process
Consideration of sustainability in needs expression, tender criteria, award weighting and contractual clauses.
Supplier evaluation and selection
Questionnaires and evaluation grids, sources of information used, supplier audits, handling of identified non conformities.
Supplier relationship and development
Dialogue with suppliers, shared improvement plans, support for small and medium sized suppliers, payment practices, balance of the commercial relationship.
Life cycle and environmental impacts
Total cost of ownership, consideration of end of life, circularity and reuse, carbon footprint of purchased categories, restraint in expressed needs.
Skills and procurement culture
Buyer training, methods and tools made available to them, individual objectives, recognition of responsible practices.
Measurement, reporting and improvement
Indicators tracked, reliability of supplier data, reporting to stakeholders, periodic review of policy and priorities.
A short version of the framework is available for the online self-assessment.
Frequently asked questions
Is ISO 20400 certifiable?
No. It is a guidelines standard, not a requirements standard: no body issues ISO 20400 certification. The maturity assessment measures how far these guidelines have been embedded into your procurement function and prepares an external evaluation should you seek one.
What is the difference between this assessment and a CSR supplier questionnaire evaluation?
A supplier evaluation rates your organisation from the outside, based on declared evidence. The assessment locates your internal practices on a progressive scale and points to the action that moves you to the next level. It is built for steering, not for scoring.
How long does the assessment take?
The short version takes 20 to 30 minutes for a procurement manager to complete. The full version, run collaboratively with category buyers, CSR and legal, typically spans one to two weeks, most of the time going into gathering the evidence.
Can the framework be adapted to our purchasing categories?
Yes. You can change the questions, levels and themes, or start from a blank base. The AI generates a variant per purchasing family or entity from your policy and internal documents, and you validate it before publishing.
How do we compare several business units or countries?
Assessments run on the same framework can be compared with one another, and each entity can be compared against its own prior results. A cross organisation roadmap consolidates action plans to avoid funding the same action twice across two entities.
Does the assessment cover due diligence and sustainability reporting?
One theme specifically addresses due diligence measures and coverage of supply chain tiers, another covers measurement and reporting. Results provide a reusable basis for your disclosure obligations, without replacing them.
What does the assessment produce once completed?
A score per theme, a target, and the gap between the two converted into an action plan. The AI groups actions into a prioritised roadmap, and the service catalogue opens a costed solution against each item, with cost, timeline and expected impact on the score.
Where is the data hosted?
In France, with OVH, backed up with Scaleway. No transfer outside the European Union. The AI models used can be selected, including from European providers.
