PSD.13:5 - Archetypal Grounding
The examples are hypothetical. Assumed specialist results illustrate the pattern; they assert no real public decision, client assessment or intervention effectiveness.
PSD.13:5.1 - A pump comparison that cannot yet choose an investment
An East-District authority asks a separate analysis team for advice on flood-pump investment for the coming season. Its receiving decision is whether and how to commit funds. The live candidates include a baseline N, fixed pumping F, mobile pumping M and staged combination S.
The qualified numerical slice concerns pumping-service loss and incremental cost, not the whole public consequence. In the stated model, F has loss 2 in normal access and 3 with road loss, at cost 8; M has loss 1 and 9, at cost 5. The baseline and staged alternative are not closed by this two-option comparison. Reachable assistance, property consequences and protected conditions still require their direct evidence and value judgements.
A sensitivity result supplies the conditional boundary 7p > 1 + 3λ for F to have the lower weighted loss, where p is the assumed road-loss probability and λ the declared cost weight in this illustrative model. Neither value has been established for the actual investment question. With λ = 0.5, p = 0.2 favours M, while p = 0.6 favours F. This is evidence of a possible reversal, not evidence that either probability obtains.
The team returns:
Retain fixed and mobile pumping for the current pumping-service/cost comparison. A whole-investment recommendation is blocked by the unqualified road-access basis, unresolved assistance and protection consequences, and the unclosed baseline/staged branches. The current model favours different options under different declared assumptions; it does not justify a preferred investment. Reconsider the affected comparison when those results or the authority’s value and protection premises change.
A material objection about reachable assistance remains in the return, not buried below the numerical result. The authority can decide what further evidence to commission under its own mandate. A bounded consequence/access request is a useful continuation when an obtainable result can improve the investment decision enough to warrant its acquisition burden. Neither that request nor the conditional comparison authorizes spending, a public trade-off or an operational response.
PSD.13:5.2 - Development advice with a positive branch and an honest gap
A committee asks a separate advisory team which direction to consider for ninety-day service reliability. The holder is the service organization; the committee is recipient and, by the assumed mandate, choice owner. Internal development, an external provider and a mixed human–AI arrangement are live directions. Critical-service continuity, a security boundary and a bounded budget are protected.
An operations account, position/interface account and strategy priority are available, but none compares the whole obtaining arrangements. The first complete return retains the three directions for consideration and states that their whole-arrangement ranking is unsupported for this horizon and protected conditions. A published Method for obtaining a comparison is not the client-specific result. A comparison request follows only if its attainable contribution warrants the full acquisition burden; the unranked answer need not propose that work.
For a separately stated continuation, suppose qualified allocation and security results now cover all three directions. They support a bounded mixed-arrangement probe, retain internal development, and exclude this provider configuration under the security condition. The probe evidence question, feasibility, exposure and stop are supplied rather than invented. The adviser can then recommend considering that probe first while retaining internal development; throughput remains uncertain and the protected conditions remain binding. These new premises, not a change of wording, permit the stronger answer.
This continuation does not promote an earlier I/H-only comparison into full-set closure. A different provider, a materially different probe, or model configuration B needs its own qualification. If the mixed result covered only configuration A, advice about B retains that qualification gap or a blocker while independently qualified internal-development content can still be returned. The committee’s later choice and probe WorkPlan are separate.
A material provider interest must be disclosed and treated under the engagement’s conflict conditions before this positive advice is relied on. A sponsor wanting one supplier does not settle the holder’s need or the committee’s choice.
PSD.13:5.3 - Unlike holders and ordinary non-use
For a person asking a separate adviser about four months of engineering-management development, suppose qualified accounts of current work show useful cross-discipline coordination experience, while an additional individual transfer study would consume much of the available horizon. The adviser can recommend considering a coordination direction within the person’s accessible work and support, with uncertainty about the four-month capability gain. This is a substantive direction for consideration, not proof of intervention effect or independent transfer. A course attendance record alone would not support that advice. When current premises support two directions without ordering them, return that retained set and its distinguishing limit; the person’s later choice remains theirs.
For an authorized team considering an AI scaffold or human–AI allocation, name the exact changed object, version, environment, evaluation validity, oversight and protected conditions. Use AI/security and, where relevant, organization-allocation results. A human learning study or a ranked recommender-system output does not establish those premises. If a known inadmissible configuration cannot meet the protected boundary, block that recommendation; if the evidence is merely absent, name the gap rather than claiming failure.
For a non-cultural population or lineage with no population-local recipient or chooser, abstain from attributing a recipient-owned development recommendation to it. Return population change to its evolutionary account. A separately authorized research team considering an intervention is a different recipient-owned case with scientific, safety and governance premises; naming that case establishes none of them.
For a chooser who already has an adequate option set and needs only to make their own decision, use direct domain or C.11 guidance. Neither an adviser nor a PSD return package needs to be invented.
