MKT.9:4.6 - Learn whether the match worked and revise the affected part

Obtain evidence that answers the question that justified the personalization. A relevant reply can establish understanding or a preference; completed access can establish a feasible transition; successful use and later benefit require their own evidence. Distinguish the quality of the selected variant from the accuracy of the information and the actual performance of the service.

When a match fails, repair the affected connection. Correct mistaken data, change the selection rule, obtain missing support, alter the variant or reopen the useful result. Do not infer that a customer segment is wrong from one failed supply case. Use MKT.12 for a consequential unknown and MKT.10 for a claimed causal gain from personalization.

Return the selected contribution or unresolved need, the grounds and limits of the choice, and the actual next result. Reuse a sufficient shared variant; create another only when a consequential difference warrants the extra construction and maintenance.
