Primaries are customary for producing an agreed slate of candidates. But it can happen that no one who participated wanted the actual outcome. Sequential Choice is suitable in this case; see the section Electing a committee with Sequential Choice in Democracy with Sequential Choice and Fund Voting.
Often a survey is carried out (preliminary voting, test voting) to get an idea of potential results before the actual voting or election, what variants of opinions or which people are most strongly supported and which have so little support that they merit no reason for further discussion. Such Sequential Choice is discussed in Collective responsibility: Sequential choice as a means of testing opinion in Democracy with Sequential Choice and Fund Voting, the matter is also referred to in chapter Sequential choice.
