問題文
A client's requirement is: reach customers whose recent behavior suggests they will lapse, on the channel each of them has permitted, with a message referencing their most recent purchase, within a day of the signal. Which chain of design decisions delivers it?
選択肢
- Ingest everything, publish the whole customer base to each channel every day with the purchase attribute attached, and let the destinations decide whom to contact.
- Ingest the behavior only, build the audience on the ingested behavior object, and let each destination look up the customer's purchases and permission on its own side.
- Ingest the behavior and purchases, unify the people, compute the lapse signal, build the audience on the unified person, and publish per channel with the purchase attribute and the permission filter.
- Compute the signal in the reporting tool and hand the list to the campaign team.
