Attributes• Conjoint analysis represents products or services as
bundles of attributes

Attributes• Conjoint analysis represents products or services as

Marketing Analytics
Attribute selection• Attributes in conjoint should be
• unambiguous• useful for determining choice or preference• actionable
• The total number of attributes should be kept low • 6 is the average
• Use qualitative research to decide on attributes/ levels• Conjoint is the end of the road, not the beginning

Marketing Analytics
Part-worths• The utility for a specific level of a particular attribute is called a
part-worth
• e.g. how much is “more” memory worth to me.
Marketing Analytics
Part-worths• The utility for a specific level of a particular attribute is called a
part-worth
• e.g. how much is “more” memory worth to me.
• It designates how much that part of the product is worth to the consumer

Part-worths• The utility for a specific level of a particular attribute is called a

• e.g. how much is “more” memory worth to me.
• It designates how much that part of the product is worth to the consumer
• Part-worths are the building blocks of the entire conjoint analysis method
Marketing Analytics
Utilities• Regression is used to translate “preference” (which may takes
different forms) data into partworths.
• The basic idea is to relate the collected experimental data to the presence or absence of an attribute• Ex: If you always choose the low price product, price must
be “important to you”
• Multiple regression is routinely used for this step
Marketing Analytics
Forms of conjoint – Response Format• Ratings-Based Multiple Regression
• This is similar to the multiple regression we covered in a separate lecture
• Choice-Based Multinomial Regression
• This gives the same type of results but the type of regression used is different.

Marketing Analytics
• Your preferences are based on trade-offs between attributes
• You are not considering one attribute at a time to evaluate your options. Instead you are considering all attributes jointly. Hence,…conjoint analysis
• Overall preference for each option = the sum of the utility that you derive from each attribute (level) or how much that attribute (level) is worth to you.
Summary
Marketing Analytics
What can you do with the results?
• Measure “part-worth” utilities
• Measure relative importance of attributes
• Predict preferences for new options even when they have never been rated.

Conjoint AnalysisSegmentation
Professor Raghu Iyengar
• The importance weights for the attributes represent the “benefits” that each respondent is seeking from the product
• Benefit segments are groupings of customers making similar trade offs (e.g., willing to pay for speed)
• Cluster analysis can be used to form groups
• Each segment is composed of maximally similar customers while each segment is as distinct as possible from the others
