A.15.1:5.3 - Work-occurrence relations used by Part B roll-ups

A.15.1 supplies the identity of each independently identified Work occurrence or Work part and makes its exact temporal and performed resource-use relations recoverable. It does not itself return a temporal aggregate or resource ledger.

  • Temporal coverage. When a receiving use needs utilization, elapsed time, phase coverage, or another roll-up over Work intervals, open B.1.4. Its recovered ContextTemporalAggregation@Context, coverage and non-overlap conditions, aggregation policy, and optional Gamma_time notation govern union, hull, or another admitted temporal aggregate. The work intervals remain A.15.1 facts.
  • Resource aggregation. When a receiving use needs a total over materials, energy, time, money, tool wear, or another performed resource value, open B.1.6. Its recovered WorkResourceAggregation@Context, typed resource-accounting basis, evidence refs, overlap or deduplication policy, ledger, aggregation rule, and optional Gamma_work notation govern the aggregate. Each contributing performed resource-use relation obtains separately with its exact Work occurrence as a participant; any ledger or assertion about that relation is a separate episteme.

Manager’s tip: cite the exact B.1.4 or B.1.6 aggregation result and policy beside the KPI. A Work-part list, shared parent, or operator spelling supplies neither the aggregate nor its policy.
