For deciding what to compare for an engineered asset, select a service-and-value question with a stated recipient, horizon and material dependencies. Adopt the proportional decision reasoning in IAM’s An Anatomy of Asset Management, version 4, July 2024, decision-making and life-cycle investment discussion (pp. 72–75). Adapt it in the Solution by identifying the requested answer before expanding the asset or information boundary. The resulting question can concern D alone while retaining a shared funding or service condition that would change its answer.

A serious alternative is to begin by preparing or refreshing the broader asset-management plan. GFMAM’s Asset Management Landscape, third edition, June 2024, section 3.4 (pp. 35–36), supplies that planning comparator. Such a plan is useful when the organization needs to settle its connected activities, rather than one already bounded option choice. For D’s question, requiring that wider planning work first would also involve assets whose treatment cannot change the comparison. The selected framing retains the consequential dependencies with less preparatory work; it deliberately gives no conclusion about the whole register or enterprise plan. Neither source prescribes CityWater’s boundary or supplies its service facts. Reopen the framing choice when an omitted dependency changes an option’s eligibility or value, the decision maker asks for a wider plan, or a changed service or horizon makes the narrow question insufficient.
