問題文
A marketing team lists the audiences it wants for next year: high spenders, lapsed buyers, frequent returners, and single-category shoppers. The consultant has to plan the computed definitions. What is the sound approach?
選択肢
- Create one very wide definition containing every measure the team could want so that all of them are computed in a single run, which minimizes the number of definitions the client has to maintain.
- Create a comprehensive set of definitions covering every attribute the model holds so that any future audience can be built without new work, because a definition that already exists costs nothing to keep.
- Wait until each campaign is briefed and create the definition then, since a measure that no campaign has asked for would only consume processing.
- Derive the definitions from the audience criteria those campaigns need, so each computed measure exists because an audience filters on it.
