Practical intelligence for accountable AI programmes.
Build a controlled AI drafting workflow that separates approved evidence from prose, assigns review decisions and records meaningful changes.

Source-grounded drafting is not a better prompt or a polished draft followed by a last-minute fact-check. It is a controlled chain in which approved sources, evidence cards, generated prose, review decisions and approval records remain separate and inspectable. Consider a pilot brief that says, “The pilot proved the workflow will save analysts time.” Its evidence may show only that a small, self-selected group spent less time preparing first drafts during measured pilot tasks. The prose sounds decisive, but it has crossed the evidence boundary.
That crossing matters when a document informs a decision, commitment, policy statement or external message. A plausible citation cannot rescue an inference the cited passage does not support. A workable process therefore exposes limitations before generation, gives reviewers specific decisions to make and preserves changes that alter meaning. The drafting model contributes language; named people remain responsible for deciding what the organisation can accept and release.
The control pattern at a glance
Generation should begin only after the team has agreed a minimum drafting packet. It identifies why the document exists, whom it serves, when it is due, what an error could affect, who owns the result and which decision or action it must support. It also fixes the approved output format and makes clear that generated wording remains a draft until the person with release authority accepts it.
The packet should state what the model may write, what it must not infer and where unresolved support must be shown. This reflects the NIST AI RMF Core's emphasis on documenting knowledge limits, intended application scope, output oversight and differentiated human-AI responsibilities. The framework is voluntary organisation-level guidance, not a mandatory content procedure, but its accountability outcomes translate well into a compact drafting brief.
Approved documents become usable drafting evidence through a source register and evidence cards, not by being dropped wholesale into a prompt. Give each source a stable identifier and record its publisher or owner, version or date, relevant scope, approval status, access conditions, known limitations and refresh trigger. Approval defines a controlled boundary; it does not prove that a source is complete, correct, current, suitable or legally usable.
For example, evidence card E-04 may permit a brief to say that participants spent less time preparing first drafts during measured pilot tasks. It should also carry the small, self-selected sample, absence of a comparison group and separate recording of review time, while prohibiting a percentage-saving prediction for analysts. NIST's Generative AI Profile recommends documenting upstream source reliance and reviewing accuracy, representativeness, relevance and suitability. Teams should add their own authority, currency and permission checks through the appropriate organisational owners.
Keep the evidence layer separate from reader-facing prose and give the model a generation contract tied to evidence-card identifiers. The contract should allow only the decision context, supported observations, unresolved risks, options and recommendations authorised by those cards. It should forbid additions from general model knowledge, vendor material, unstated policy interpretations and invented citations, while requiring a conspicuous marker such as [EVIDENCE NEEDED] wherever support is missing.
A citation is a route back to evidence, not proof that the neighbouring sentence follows from it. The NIST Generative AI Profile recommends reviewing and verifying sources and citations in generated outputs. Keep evidence cards, instructions, prose and approval records as distinct artefacts so a reviewer can inspect support without mistaking fluent interpretation for source material. The drafting model must not be the only fact-checker of its own consequential claims.
Each material review question should have a named decision owner. The source owner confirms the approved set; an evidence reviewer compares consequential clauses with cards and underlying passages; an editor improves structure and audience fit without changing evidentiary meaning; a specialist reviews triggered domain or policy issues; and an approver accepts the recommendation, conditions and residual uncertainty. NIST's AI RMF Core supports clear roles, communications and differentiated human-AI oversight.
A small team may give several roles to one person, but it should preserve the separate questions and record who made each decision. For long or consequential work, review bounded claims or clauses rather than relying only on an overall impression. LongEval found reduced annotator disagreement from finer-grained judgements across two long-form summarisation datasets. Applying that result to business drafting is a practical inference, not a universally measured benefit.
Automated claim-to-source checks can help route suspicious clauses or assemble evidence links. NIST's experimental grounding work pairs an authoritative corpus with cited reports, citation evaluation and structured evidence-linked results. That work illustrates an inspectable pattern, but it is evaluation research rather than a finished standard. Automated checks can assist review; they cannot accept specialist risk, residual uncertainty or release responsibility on an organisation's behalf.
A grounded draft is one whose consequential claims can be traced, challenged, corrected and knowingly approved.
Record an edit explicitly when it changes factual meaning, interpretation, a recommendation, a commitment, an obligation, risk treatment, source basis or approval status. Ordinary spelling, style and formatting changes can remain in normal version history unless organisational policy requires more. This proportional test preserves the decisions that matter without turning every comma into a governance event or imposing a universal retention rule.
In the pilot example, replace “The pilot proved the workflow will save analysts time” with “In the measured pilot tasks, participants spent less time preparing first drafts; the small, self-selected sample does not establish the effect for analyst work.” The record should show the before and after wording, the reason for removing the unsupported inference, affected evidence card E-04, reviewer, approver and decision time.
The NIST Generative AI Profile describes provenance metadata that can include creators, dates, modifications and sources, and recommends maintaining content-change records with associated metadata. It does not prescribe one retention period. The organisation should decide which prompts, inputs, outputs, draft versions and edit records to preserve according to business need and the requirements set by its records, information-governance, privacy, security or legal owners.
The control pattern should remain consistent while its weight changes with the document's purpose and consequences. A decision brief needs visible ownership, supported options and acceptance of uncertainty. An analytical report needs method, scope and clause-level evidence work. A routine message can rely on a compact set of approved facts and sender review. Length is not the risk measure: a short message creating a substantial commitment may warrant deeper scrutiny than a long, low-risk summary.
| Document type | Minimum drafting packet | Required review | Escalation triggers |
|---|---|---|---|
| Decision brief | Decision owner, deadline, consequence, approved evidence, supported options, recommendation, uncertainty and conditions | Claim check, triggered specialist review, final approval and consequential-edit record | Unsupported recommendation, material commitment, sensitive information or unresolved policy question |
| Analytical report | Defined question, scope, method, dates, exclusions, source register, evidence cards and alternatives | Clause-level evidence pass, suitable method or domain review, approval and source-version record | Changed method, disputed interpretation, missing source coverage or specialist judgement |
| Routine communication | Recipient, purpose, sender, channel, approved facts, dates, names, links and fixed language | Sender check using a suitable approved tool | New commitment, exception, sensitive content, novel claim or departure from fixed wording |
Use these as starting templates rather than universal checklists. A routine message may need only approved details, a clear requested action and a sender check, yet it should be escalated if it introduces an exception or novel claim. Conversely, a lengthy internal summary with little consequence may not justify the same specialist path as a concise executive recommendation. The drafting packet should explain why its selected controls fit the document.
Reliability requires a modest operating cadence around the workflow, not simply more review at the end. Assign an owner to revisit a source when its facts, version, relevance, permissions or organisational status changes. The NIST Generative AI Profile recommends defined periodic-review responsibilities for content provenance and documented human oversight roles. How often review occurs should follow the source's volatility, purpose and organisational requirements rather than an arbitrary universal schedule.
Define an exception route before it is needed. If a source falls outside the approved boundary, or a sensitivity, permission, policy or specialist-review trigger appears, pause the affected work and send the issue to its named owner. Record the boundary decision and resume only when the source set or exception has been explicitly resolved. The model should neither interpret the applicable requirement nor grant itself permission to continue.
Recurring corrections are design evidence. If drafts repeatedly turn a limited observation into a broad promise, strengthen the evidence card's prohibited inference, adjust the output template or narrow the generation contract before adding another downstream reviewer. Begin with one recurring document type and make its source boundary, decision rights, exception route and edit rule visible. Consult the appropriate organisational owner whenever sensitive information, uncertain permissions, regulated statements, contractual commitments, specialist judgements or retention obligations are involved.
It is a controlled process that approves source and information boundaries, converts relevant passages into qualified evidence cards and constrains generation to that evidence. Consequential claims are then checked against the underlying passages, reviewed through named decision rights and accepted only by an accountable approver.
Separate evidence checking, editorial review, triggered specialist review and final approval because they answer different questions. For consequential content, compare bounded claims or clauses with the underlying passages rather than relying solely on a document-level impression.
No. Citations improve traceability, but their presence does not prove that a claim follows from the cited passage or that the source is accurate, complete, current and suitable. A reviewer must inspect both the claim and the relevant source material.
There is no universal keep-everything rule. Preserve prompts, inputs, outputs, draft versions and edit records according to the document's purpose, risk and business need, together with applicable requirements determined by the organisation's records, privacy, security, legal and information-governance owners.
Automated checks can flag possible mismatches, map claims to passages and support review triage. They cannot decide whether residual uncertainty, specialist risk or a consequential recommendation is acceptable. Those decisions remain with the named human owners and approver.
