2. What is Worldone’s conjoint capability?
WorldOne is capable of handling all projects utilizing a conjoint module from basic hosting to design,
programming, analysis, utility computation and simulator building. We have the ability to direct our survey
link to external conjoint modules, and administrate and host it based on client design, as well as manage
conjoint from design phase up to simulator building.
different types of conjoint analysis
Discrete choice MoDeling (DcM) /choice-BaseD conjoint (cBc)
Choice-Based Conjoint (CBC) is used for Discrete Choice Modeling (DCM), a research technique that
is the most widely used conjoint-related method in the world. The main characteristic distinguishing choice
based from other types of conjoint analysis is that the respondent expresses preferences by choosing
from sets of concepts, rather than by rating or ranking them. The choice-based task is similar to
what buyers actually do in the marketplace. Choosing a preferred product from a group of products
is a simple and natural task that everyone can understand.
aDaptive conjoint analysis (aca)
ACA is a computer-administered interactive conjoint method designed for situations in which the number
of attributes exceeds what can reasonably done with more traditional methods (such as CBC or traditional
conjoint-CVA). ACA focuses on the attributes that are most relevant to the respondent and avoids information
overload by focusing on just a few attributes at a time. The scope of many studies has also been constrained
by limitations in respondents’ time and attention. ACA moves beyond those limitations by adapting the
interview for each respondent.
Max Differential exercises (MaxDiff)
MaxDiff is an approach for obtaining preference/importance scores for multiple items (brand prefer-
ences, brand images, product features, advertising claims, etc.). Although MaxDiff shares much in
common with conjoint analysis, it is easier to use and more applicable to a wider variety of research
situations. MaxDiff is also known as “best-worst scaling.”
aDaptive choice-BaseD conjoint (acBc)
ACBC is our most advanced system for conjoint/choice analysis. It is used for studying how people make
decisions regarding complex products or services. ACBC is a new approach to preference modeling that
leverages the best aspects of CBC (Choice-Based Conjoint) and ACA (Adaptive Conjoint Analysis). An
Adaptive Choice interview is an interactive experience, customized to the preferences and opinions of
each individual.
Which platform is conjoint administrated?
WorldOne utilizes Sawtooth software to administer conjoint modules. Sawtooth has created products for
traditional conjoint analysis and discrete choice analysis, as well as and other forms of conjoint analysis.
