4. Discrete Choice Conjoint Analysis
Trade-off analysis
methodology
#1 Methodology used
research technique
for customer
purchase decisions For any purchase, consumers evaluate or “trade-off”
the different characteristics of a product and decide
what is more important to them
5. Do You Conjoint? Why You Should
New Product
Research
- Evaluate new
products or
variations against
existing range of
products in the
marketplace
Budget Friendly
- Cheaper than
developing new
products for the
marketplace with no
guarantee of success
Simulates Consumer
Decision
- Captures how target
audience react to new
products/services
within marketplace
-Refine the target
audience for your study
Real Time Data
- Need this data quick?
Don’t wait. Get real-
time feedback on new
products or variations
of existing products
today
Analyze Choice vs. $
- Gauge the effect on
the choice/price
relationship relative
to existing products and
features presented
6. QuestionPro’s 3-in-1 Design Options
Random Design
- Most Popular among
QP customer
- Easy to program
- Easy to analyze
- Easy to include in
comprehensive
surveys
D-Optimal Design
- This algorithm will
produce optimal
number of tasks per
respondent based on
sample size to reach
statistical significance
Import Design
Caution*
- Available for those who are
statistically savvy. Must be able
to calculate margin of error
from your own design
-Externally create conjoint
design with custom algorithm &
Import into QuestionPro

Designs
7. Best Time For a
Discrete Choice
Conjoint Study
Business Objective: Market Share
Growth New Product/Services
Beginning of Innovation Process
During Product/Service Planning &
Prototyping
Cost of Overhead vs. Potential
Revenue
When you have a Statistically
Significant Target Audience
9. Where to Get Started
● Qualitative Research - Validate Anecdotal Info
● Identify Top Attributes & Levels for research
● Focus group or surveys with open-ended
questions will help define your top attributes
needed for your study
● Use Crowd-sourcing tools or forums: QuestionPro
Communities or IdeaScale
● Define range & language for target audience
10. Best Practices
❏ Keep options clear and simple
❏ No more than 20 trade-off exercises
❏ No more than 5-6 attributes
❏ Keep ranges simple
❏ Follow general good online survey techniques
❏ Beta test survey before launch date
❏ Exercise good privacy & confidentiality protocols
❏ Keep survey short & sweet
❏ Provide incentives or rewards $ for long surveys
11. Best Practices for Sample Size
❏ Sample size recommendation: (nta/C) > 1000
n = number of respondents x t= number of tasks x a= number of
alternatives per task / C= largest number of level for any one attribute.
❏ Example: 500 respondents, 3 tasks per respondent, 2 alternatives per task
and the maximum number of levels on an attribute is 3
(500 x 3 x 2) / 3 = 1000
❏ Generally speaking sample sizes tend to be around 200 – 1200 respondents, admittedly
a wide range
❏ 300 comes up most often for a single homogeneous group of subjects

15. The Analytics
How do we come up with our numbers
for Parts Worth Calculations?
QuestionPro’s Discrete Choice Module uses
a Maximum Likelihood calculation coupled
with a Nelder-Mead Simplex algorithm
Have greater confidence in
the results you receive!
16. What’s the Market
Segment Simulator
Going to Tell Me?
Market Segment Simulator gives ability to "predict" market
share of new products and concepts that may not exist now
● Measure the "Gain" or "Loss" in market share based on
changes to existing products in the given market
Conjoint Simulation Rulebook
Identify “Profiles” - different products or concepts to investigate
Review existing products in current market segment & simulate market
share of the products to establish a baseline
Try out new services and ideas. See how the market share shifts
based on different products and configurations from data collected
