How to prepare an executive decision memo with AI

Frame the decision before summarizing evidence

Write the decision as a sentence containing the owner, choice, timing, and boundary. For example: “Should the programme sponsor fund a three-month pilot now, defer until source access is resolved, or stop the proposal?” Define success conditions and constraints before evaluating options.

The UK Green Book describes appraisal as comparing costs, benefits, and risks of options against objectives and communicating uncertainty to decision-makers in its public-sector context. UK safety leadership guidance describes a decision cycle that considers time, diagnosis, options, action ownership, and review. These sources support disciplined choice framing, not the answer to a private organization’s decision.

Build a source map before drafting:

| Memo claim | Evidence | Strength | Limitation | |---|---|---|---| | Pilot can start in October | Capacity plan and owner confirmation | Direct | Security review not complete | | Three teams fit the scope | Approved roster | Direct | Availability may change | | Delay reduces learning this quarter | Programme calendar | Inference | No measured commercial effect | | Integration is unnecessary for pilot | Technical design note | Supported | Applies only to synthetic data |

Ask AI to detect claims with no source and evidence that contradicts the preferred option. Review every result against the original material.

Compare genuine alternatives

Include business as usual or defer when it is viable. Apply the same objectives and constraints to each option. Do not use a detailed description for the favored option and a caricature for the others.

This synthetic decision table supports the example:

| Option | Benefit | Cost or burden | Key risk | Reversible? | |---|---|---|---|---| | Run bounded pilot | Earlier workflow evidence | Reviewer and setup capacity | Access review may delay start | Yes, after pilot | | Defer one quarter | Resolve access first | Learning delayed | Cohort may no longer be available | Yes | | Stop proposal | Avoid current effort | No pilot evidence | Need remains unresolved | Partly |

The recommendation might be to authorize preparation but make participant invitations conditional on access approval. The memo should name that condition and the person who decides whether it is met.

Connect the recommendation to tradeoffs

State why the preferred option best meets the defined objective under current evidence. Then name its strongest disadvantage, material uncertainties, and the evidence that would reverse the recommendation. This is more useful than a list of generic risks.

A failure example says, “Proceed because the pilot is low risk and strategically aligned.” Those labels are unsupported. A repaired sentence says, “Proceed with preparation because the synthetic-data design avoids the unresolved integration dependency; do not invite participants until the security owner approves the data path.” The rationale now points to evidence and a boundary.

Keep facts, estimates, assumptions, and judgments visibly distinct. If a cost is an estimate, show its basis and range. If the conclusion depends on a hypothesis, state how it will be tested.

Design the decision and follow-through

End with the exact approval requested, conditions, owner, next action, review date, and record location. An executive should not need to infer what signing the memo authorizes.

Before sending, verify:

The artifact is the memo plus claim-to-source map, option table, uncertainty register, and signed decision. Keep detailed analysis linked rather than crowding the executive page with unsupported compression.

• the decision is singular and time-bounded;
• viable alternatives use the same comparison basis;
• each material conclusion maps to a source;
• contrary evidence and uncertainty are visible;
• the recommendation explains tradeoffs rather than repeating the objective;
• reversal conditions are concrete;
• approval authority and conditional gates are named; and
• the decision record can be updated without erasing the original basis.

Sources and claim map

The pilot, options, evidence, and recommendation are synthetic. This educational method does not assert a Two Prune roadmap, approved expenditure, or measured outcome.

• HM Treasury, The Green Book 2026: supports objective-led option appraisal, tradeoff analysis, evidence use, and explicit uncertainty in its scope.
• UK Government, Decision making and risk management: supports the limited time, diagnosis, options, assignment, and review sequence.
