HCD.8:4.2 - Compare Obtaining with Building
Construct at least one feasible route when one exists:
| Comparison position | Obtain an existing contribution | Build the missing contribution |
|---|---|---|
| result fit | Evidence that the provider or environment can supply the exact result | Target task and proposed change capable of producing that result |
| time and window | Onboarding, contracting, access, calibration, and actual availability | Preparation, practice, correction, retest, installation, validation, and ramp-up |
| burden and risk | Search, handoff, confidentiality, continuity, dependency, and switching burden | Development effort, supervision, failure exposure, maintenance, and displaced work |
| authority and independence | Permission, accountability, assessment independence, and domain legitimacy | Who can authorize, judge, and operate the created contribution |
| operating evidence | Representative sample or observed service under the intended conditions | Representative operating test after preparation or change |
| continuation | Renewal, backup, transfer, or replacement condition | Maintenance, refresh, supervision, fallback, and smallest reopen condition |
Prefer neither route by default. An existing provider is not sufficient because of reputation or title, and a local build is not superior because it creates internal capacity. Return the surviving non-dominated route or routes, with unresolved trade-offs for the current contribution, window, burden, risk, continuity, and evidence use; the authorized programme decision remains separate.
