Turn a working question into an analysis, then recover its meaning
Define one alternative precisely enough to tell which work and assumptions change. Alternative A retains the existing displays and uses manual correction. Alternative B installs the proposed replacement and uses its automatic counts. For the initial comparison, suppose staffing for A is available and the supplier has described a technically plausible B, while B’s installation interval and whole cost remain unknown. Do not compare A in its troublesome current state with B in an unexplained ideal state.
An initial analysis value expresses an observation or an assumption in this particular question. To ask what B would change if installed and operating as proposed, provisionally assume that installation and specified sensing performance hold. Mark both as assumptions. Keep the unresolved installation and cost questions attached to the investment decision. A conditional service comparison can proceed without pretending those inputs have been obtained.
Likewise, leaving manual rounds out of B means they are not part of that proposed arrangement. It is not evidence that attendants cannot inspect a floor. An uninvestigated element stays uninvestigated; an investigated effect may remain unknown; opposed grounds may remain in conflict. Neither omission nor uncertainty means a negative observation.
Carry each alternative through the relationships using PSD.11’s qualitative branch. Keep the initial assumptions and intermediate judgements with its result. For A, a sufficiently recent and correctly performed round supports a corrected count; publication still needs the working display. For B, the stipulated sensing performance supports the count conditionally; it does not establish the installation date or remove all future maintenance work.
Contributions require the relevant person’s or specialist’s judgement when the incoming grounds do not settle the answer. Here management judges that fewer misleading indications would help reputation. It cannot infer satisfactory reputation from that improvement alone while the protection concern remains unanswered. The same extra staff work that supports accurate guidance also adds operating burden. Do not cancel these effects by counting favorable and adverse arrows.
Return an answer in the language of the original inquiry:
| Question | A: retained system with manual correction | B: proposed replacement |
|---|---|---|
| Can it provide useful counts? | Supported only while the stated inspection, freshness, staffing and publication conditions hold. | Supported conditionally on the proposed installation and sensing performance. |
| What happens to work and cost? | Inspection remains a recurring demand. | Some inspection may be displaced, but acquisition, transition and operating costs remain to be established. |
| Does it meet the concerns behind reputation? | Better count information addresses one concern; protection of cars needs its own grounds. | The same limit applies; a better sensor is not evidence of protection. |
This comparison does not yet justify the investment. It identifies what the proposal can improve and which missing facts can change the choice. Obtain a bounded installation and whole-cost answer if its expected contribution warrants the work; otherwise retain the conditional comparison or defer the choice. The answer is not “B has more satisfied goals”.
