STR.9:5 - Archetypal Grounding

STR.9:5.1 - SensorCo: preparation beats a viable rival only under stated conditions

All facts in this case are constructed. SensorCo can sustain its current device and service contracts for twelve months. The Board seeks a repeat paid contribution less exposed to generic-inspection price competition while protecting service and incident reserve.

Two prospective customers may discuss a bounded paid service trial next quarter at a price ceiling, subject to agreement and permitted use. Four funded internal days before the next Board consideration can complete costing and specify a possible trial. They could instead improve device diagnostics.

The current comparison concerns those four days and their contribution to the twelve-month question. It does not compare an already successful service business with an assumed failing device business.

For the exit comparison, assume that orderly exit and device continuation both satisfy the protected-service requirement under the three conditions below. The supplied comparison for this twelve-month decision includes the exposure avoided, net disposal proceeds, the best attainable use of released resources and any later consequence material to the choice. Under the Board’s criterion, exit’s supported advantages are outweighed by the continuing device contribution forgone and the full customer-transition burden.

Condition at the relevant horizonComparison with device-only continuation and diagnostic workSupported return
Commoditization continues and an accountable-service opportunity remains attainablePreparation can establish whether a relevant service arrangement is economically plausible; diagnostics improve the viable current direction but do not answer that questionPrefer the bounded preparation at the Board’s accepted four-day sacrifice; keep the twelve-month service direction open
Purchasing freezes throughout the horizon, preventing a useful paid trialThe preparation no longer has the stated opportunity to inform this choice; device continuation supports existing obligationsPrefer device-only continuation and retain the four days for diagnostics
Data reuse is restrictedA permitted customer-local service might still be possible, while cross-customer licensing requires its own rightContinue preparation only if an attainable determination leaves a relevant permitted option; otherwise prefer device continuation

The criterion is the Board’s supplied trade-off, not a universal demand for experimentation. The third row is conditional rather than automatically pro-service. Licensing is not currently selectable without its required reuse right. Under the supplied whole-consequence comparison, continuation is preferable to exit. Reopen that comparison if an exit benefit, transition burden, continuing contribution or protected-service condition changes enough to reverse it; continuation need not become infeasible for exit to become preferable.

A complete cost calculation can also close the service question. If no relevant permitted configuration can cover delivery cost at attainable customer terms, the recommendation is device continuation without a trial. If a cost component is missing, the comparison remains unresolved.

Later capacity arithmetic answers another question. A proposed 78-person-day configuration fits the stated 80-day ceiling with protected service and reserve, but that alone does not show strategic merit or delivery capability. Within its six platform days, two preserve device-compatible interfaces and instructions, postponing a two-day service-diagnostic enhancement. That is the cost of the fallback through the first staged decision. It differs from the four-day device improvement forgone in the present preparation choice.

STR.9:5.2 - The criterion can change the answer even when the numbers do not

In a separate constructed public-service comparison, assume two configurations satisfy the supplied protected-access condition. A qualified model for this illustrative use gives the following waiting times under two stated demand conditions; neither condition has an assigned probability.

ConfigurationCondition 1: waiting minutesCondition 2: waiting minutesWorst waiting time
A101212
B41616

If the responsible chooser minimizes the worst waiting time, A is preferable: 12 rather than 16 minutes. If the declared criterion instead minimizes maximum regret in waiting time, the best result in condition 1 is 4 and in condition 2 is 12. A’s regrets are 6 and 0; B’s are 0 and 4. B then has the smaller maximum regret, 4 rather than 6.

Neither calculation changes the stipulated waiting-time estimates or selects the public value rule. The practitioner returns the consequence of each rule for the responsible judgement. If B failed the protected-access condition, its smaller regret would not make it eligible. The example demonstrates a comparison distinction, not a public-policy prescription or a validated forecast.

STR.9:5.3 - SensorCo: two improvements can share one receipt

Consider a constructed later costing comparison, separate from the current four-day preparation and its authority. It concerns a device-health report offer, an alert offer and their combination for one prospective customer over the same twelve months.

Assume that either offer, or both together, would produce one incremental payment of 10,000 currency units at month 12 under the stated acceptance and payment conditions. The customer pays for one service, not for the number of independently developed features. The complete future additional payments within the horizon are 6,000 for reports, 5,000 for alerts and 11,000 for both. Existing receipts and payments remain unchanged, and the supplied account establishes no other material displaced contribution. Funding when payments fall due, resources and permitted service conditions are assumed available for this calculation; the arithmetic does not establish them.

Compared future arrangementIncremental receiptFuture additional paymentsIncremental net cash over twelve months
Continue without either new offer000
Reports only10,0006,0004,000
Alerts only10,0005,0005,000
Reports and alerts10,00011,000−1,000

Adding the two standalone net returns would give 9,000 by counting the same possible receipt twice. Under these assumptions, alerts have the strongest net-cash result. That is a conditional financial comparison, not the full strategic preference, an authorized service commitment or realized revenue.

Now change one premise: a qualified customer basis supports a further 8,000 payable only for the combined offer, with the other cash consequences unchanged. Its receipt becomes 18,000 and its net cash 7,000, reversing the financial ranking. If that extra payment is unsupported, keep it as an unresolved premise rather than adding it or silently setting it to zero. Combining improvements is not intrinsically bad; their actual joint contribution decides this comparison.

A supporting rate needs the same care. In a separate constructed account, two distinct results each pay 100 units on completion and take two and four hours sequentially on the same resource, with no other delay. Together they yield 200 over six hours, or 33⅓ units per hour, not the sum of their standalone rates, 75. By contrast, independent streams paying 100 and 50 in the same one-hour interval can jointly yield 150 in that interval. Recover the quantities, conditions and interval before aggregating.

These are undiscounted cash comparisons under supplied conditions. Earlier funding requirements and any material financing, timing or later effects still need the qualified account appropriate to the actual choice. The current preparation can obtain missing costing or customer answers without claiming that this later comparison has already occurred.

STR.9:5.4 - SensorCo: a central workload can hide the service exposure

This constructed extension examines the proposed 78-engineer-day first-month configuration, not the earlier four-day preparation decision. Fix its service scope, team and thirty-day window. A stipulated operating model gives total engineer-day demand, including the protected eight-engineer-day incident reserve, when zero, one or two additional trial requests arrive. These three request conditions are the model’s stated test domain; none has an assigned probability.

Additional trial requestsTotal required engineer-days, including reserve
078
179
284

The PSD.12 paired comparison gives a central response of 79 engineer-days and an endpoint mean of 81 engineer-days, a two-engineer-day gap. This is not an expected workload. More importantly, the two-request response exceeds the actual 80-engineer-day capacity by four engineer-days. The central case’s apparent fit therefore does not establish that the service scope can be supported under all three conditions. Removing the protected reserve is not an admissible repair.

One proposed response is to limit trial admissions to one and defer additional requests. That only narrows exposure if the actual customer terms permit deferral, the remaining service is a useful complete contribution, and the required admission and support arrangement is feasible. Those premises are not supplied here. The return is these three unanswered questions, alongside the failed two-request condition, not an asserted workload cap or a selected service commitment.

The Board can use permitted preparation to clarify that narrower arrangement and its full cost if this can change the choice. Existing device continuation remains a serious alternative. The earlier preparation authorization neither establishes the response model nor funds or limits a future service promise. A sufficient current capacity and terms account would be reused without another test.
