Adhoc studies

The Latin phrase Adhoc literally means « for this », appropriate for a specific situation, made for a specific objective.
In the marketing language, an Adhoc study is a one-time punctual study, made in a specific way on a precise subject, for a specific ordering customer (conducted generally by a research firm).
