DOCA.6:11 - SoTA-Echoing

Practice question. How can development inquiry retain later possibilities and useful intermediate steps without forcing a current winner or disguising an unqualified sequence as a programme?

Best-known line for this use. Retain candidates for an explicit later use, while comparing each finite step from its own inherited configuration. This pattern adapts C.18’s distinction between archive exploration/stepping-stone value and current-front non-domination in :4.1–:4.2 and :4.5. It adopts C.11.CRC’s finite comparison and option-effect discipline in :4.3. C.19 supplies actual live-pool treatment, not a local next-probe choice.

Serious alternative and trade-off. Retaining only the current front is useful when immediate comparison is the whole question. It loses a presently weaker candidate whose supported enabling relation matters to a later use. Keeping an unrestricted backlog avoids that loss but hides retention costs and defeated premises. At the modest effort of the index case, adding a retention reason and a stage-specific increment exposes both the possible later use and the extra maintenance burden. The cost is reconsidering conditions that a static list ignores; comparative efficiency has not been measured.

Organization-specific source return. Proactive portfolio management in mission-oriented innovation policy, OECD, 2025, sections 2–4, supplies a current answer-bearing line on complementary activities, development-stage dependencies, resource distribution, adaptation, and termination. This pattern adapts those interdependence and reconsideration concerns in :4.1, :4.3, and :4.6. The source’s mission-management scope includes selection and funding; opportunity retention here supplies inputs to those separately authorized moves. It establishes neither a universal three-horizon rule nor a person- or AI-development mechanism.

Limits and reopen. The constructed cases show what must be distinguished; they do not demonstrate future option value or intervention effectiveness. This is not a complete comparison of investment-portfolio or real-options methods. Return such a specialist comparison when the receiving use requires valuation or allocation. Reopen the affected retention rule when a serious alternative preserves the needed possibilities at lower burden, the enabling evidence fails, or the governing use, source, horizon, or resource condition changes.
