ECO.7:4.3 - Test ordinary use and changed conditions

Run a concrete allocation and renewal case through the proposed rules. Include a plausible change such as low supply, new entry, a failure to contribute or a disputed reading. Determine who detects the change and which decision can adapt the arrangement.

Return the feasible arrangement, a limited trial or the unresolved constraint. A few measurements that discriminate the choices can be enough; a complete social survey is not automatically required. Revisit physical conditions, access and rule effects when their change invalidates the arrangement.
