  6. 6. What is Conjoint Analysis ? Conjoint analysis is a method developed over the past 50 years by market researchers and statisticians to predict the kinds of decisions consumers will make about products by using questions in a survey. The central idea is that for any purchase decision consumers evaluate or “trade off” the different characteristics of a product and decide what is more important to them. For instance , it may be that the container size is the most important factor, or it may be environmental friendliness of the product and the price. Obviously for different products there are a whole range of possible characteristics or “attributes” that consumers may take into account. Conjoint analysis is away of presenting a set of possible products to consumers via a survey and ask them to make a choice about which one they would pick. A set of attribute for a product (perhaps color, size, price) are chosen and then a set of “levels” of the attributes are selects. For instance we could have 3 colors of a product, red, green and blue, then maybe 3 sizes, 4, 8 and 12 oz, then 3 prices, $10, $20 and $30 . This would give 3 x 3 x 3 possible product combinations. A set of alternative “products” based on the attributes you have defined are presented to respondents who  make choices as to which product they would purchase in real life. It is important to note that there are a lot  of variations of conjoint techniques. SA uses a conjoint technique which we feel best simulates the purchase  process of consumers.
  7. 7. Why use Conjoint Analysis ? Conjoint analysis is used to help evaluation new products, or variations of products, against an existing range of products or a marketplace. It is very expensive to develop a new product and then put it out into the marketplace with no guarantee of success. Conjoint analysis allows market researchers to simulate the decisions consumers would make in the market place. This means a company can get an idea about how a new product with be received in the marketplace much more easily than if they had to really develop and market the product. It is also used to see what effect changes in price of existing products may have on the sales of the product. With Survey Analytics conjoint analysis system you can get feedback on new products or variations of an existing product very quickly and at a low cost.
  8. 8. 1) Attributes/Feature: Define the attributes of the products for your market. These are the properties of your product. Seattle Tourism Study: vs. Hours, Time of Day, Tour Type 2) Levels: The different properties of the attributes. Define at least two levels for each of the attributes. Seattle Tourism Study: Hours - 3 levels Time of day - 4 levels Tour Type: 5 levels 3) Utility or Part Worth functions: These are what are produced by the conjoint analysis. These can then be used to determine how important an attribute is to the purchase or choice process and in “market simulations”. 4) Relative importance: how important an attribute is in the purchasing/choice decision ? Core Concepts
  9. 9. (1)Survey Analytics uses Multinomial Logistic  Regression for part worth calculations. Used in calculating utility values for each level (2) Survey Analytics use an Orthogonal Profile  Generation Any set of attributes will have a minimal set of profiles that can be generated to form a balanced design. Have greater confidence in the results you receive! Analysis

  23. 23.   Market Segmentation Simulator Using existing Data from Conjoint Analysis 
  24. 24. Market Segmentation Simulator Gives you the ability to "predict" the market share of new products and concepts that may  not exist today.  Ability to measure the "Gain" or "Loss" in market share based on changes to existing  products in the given market. Important steps in Conjoint Simulation: 1- Identifying and describing the different products or concepts that you want to investigate.  We call these "Profiles". Example one of the profiles could be: Tour Type: Weird, Hours: 1-2 , Time of Day: Evening 2- Find out all the existing products that are available in that market segment and simulate  the market share of the products to establish a baseline.  3-Try out new services and ideas and see how the market share shifts based on new  products and configurations.
  25. 25.   Let's look how to set up a Simulator!
  26. 26. Setting Up Simulator: 1) Click on Online tools >>Name Simulator Profile>>change  profiles      2)Click                                             to see results . . . . .
  27. 27.  Results: Simulator Output Defined   The market simulator uses utility values to project the probability of  choice and hence the market share 
  28. 28.   Now that we know  how to use this . .     What can we ask and find out with the  Market Segmentation Simulator?
  29. 29. Market Segmentation Simulator In our second example we have a 20%/80% split of market share when  we just vary the DVD or DVD with Podcast feature. What happens if we  change the guide to family guide from separate adult and children’s  guides ? Answer: The market share for the Family guide with DVD option goes  down to 10% from 20%
  30. 30. Market Segmentation Simulator In our first example what happens if have a tour of 1-2 hours as opposed to 4-6 hours in the afternoon for “Weird Seattle” ? Answer: We find that the 1-2 hour tour would attract about 75% of the market share.
  31. 31. Market Segmentation Simulator Using our second example, what happens if we take the most preferred profile and change the family exercise calendar from 60 days to 30 days ? What effect does the 90 day calendar have ? Answer: We get a 60% market share for the 60 day calendar vs 40% for the 30 day calendar. A 90 day calendar vs a 60 day calendar has 30% market share for the 90 day calendar and 70% for the 60 day calendar. 60 days 60% 30 days 40% 60 days 70% 90 days 30%
  32. 32. Best Practices Tips for Successful Conjoint Analysis Studies
  33. 33. You must use qualitative research first! What are the top attributes? What range? What language? A focus group or surveys with open-ended questions will help define your top attributes needed for your study Best Practices & Tips
  34. 34. You need some numbers to get good statistics Best Practices & Tips Sample size is a question that comes up very frequently. Richard Johnson , one of the inventors of conjoint analysis, has presented the following rule of thumb for sample size in choice based conjoint: (nta/C) > 500 Where n = the number of respondents, t= the number of tasks, a=the number of alternatives per task , C= the largest number of level for any one attribute. So if you have 50 respondents, 3 tasks per respondent, 2 alternatives per task and the maximum number of levels on an attribute is 3 you get: (50 x 3 x 2 x 3) = 900 The general opinion now seems to be that 500 may be too small a number, 1000 is a better value. Generally speaking sample sizes tend to be around 200 – 1200 respondents, admittedly a wide range. It does seem that the value of 300 comes up most often for a single group of subjects.
  35. 35. Keep the options clear and simple as possible No more than 10-12 trade-off exercises (5-7 standard) No more than 5-6 attributes Keep the ranges simple You can ask more intimate questions of current customers than potential customers, but don’t let that stop you from trying! Follow general good online survey techniques Test your survey Make it clear responses keep strictly confidential Keep survey results to 15-20 minutes Provide incentives Best Practices & Tips
