In a Conjoint study, it's difficult for respondents to evaluate more than 6 product attributes at a time.
Often this is solved via the use of Adaptive Conjoint Analysis (ACA), in which the questionnaire is modified for each individual respondent as the survey is being taken. In ACA, it is not necessary to show the full profile -- i.e. all attributes -- of each product. Partial profiles are shown. A study can include up to 30 attributes, but respondents are never asked to consider more than 5 at a time.
However, in order to do ACA, as far as I know of at this time, one must have the survey hosted by a very expensive (e.g. $10,000) conjoint-oriented survey host.
My question is, is it possible to do partial profile Conjoint, without using ACA?
