In 2009 Sawtooth Software launched ACBC
(Adaptive Choice Based Conjoint)
As many researchers we expected a new “power tool” and increased value
for our projects.
Following presentation report our experience illustrated with base case from
a commercial study…

Case Study: Background
ü Chemical Product for DIY market
ü 14 attributes including price, many non compensatory
attributes
ü Difficult to find target group (“Moonlighters”)
=> small sample N=200
ü Objective: Product development & identification of best USP
ü No focus on price

Design Considerations
Prohibitions
Initial prohibitions led to huge design problems
No Standard Tool to “test design efficiency” in ACBC
=> Be careful and avoid as possible
" Only one prohibition was used
16. Stefan Binner, bms-marketing research + strategy, Germany
NewMR Advanced Quant Techniques, July 14, 2011
Design Considerations
Price Attribute
v Price range +/- 50%
v Rounded to 99 cents
v Prices was used in unacceptable section
v Level Prices for selected attribute levels were used in 7 of
13 non price attributes
17. Stefan Binner, bms-marketing research + strategy, Germany
NewMR Advanced Quant Techniques, July 14, 2011
Design Considerations
Holdout Tasks
§ No easy holdout tasks like in CBC
§ Calibration concept no substitute for holdout tasks
§ Possible Solution:
Use one random tournament question as holdout
18. Stefan Binner, bms-marketing research + strategy, Germany
NewMR Advanced Quant Techniques, July 14, 2011
Pre Testing
N = 20 Pretest
§ Internal Pre-Test indicated too long and complex interviews
§ Real Pre-Test were promising: respondents liked the
questions and found good sense in them
§ => we increased the number of questions slightly

Field Work
N = 200 face-to-face CAPI
§ Good response
§ Happy respondents
§ Relevant questions
§ Positive feedback
§ Average duration around 30 minutes

Results
Price
§ Linear price function result in very large price interval with
only few data points at the end of the interval
(base price + all possible level prices +/- 50%)
§ Use of piecewise price function with 5 data points
§ Check data! (get_acbc_prices.exe tool)
§ Rather flat price elasticity which needed calibration
22. Stefan Binner, bms-marketing research + strategy, Germany

Price
§ Due to the large interval price the IMPORTANCE of might
gets over-estimated

31. Stefan Binner, bms-marketing research + strategy, Germany
NewMR Advanced Quant Techniques, July 14, 2011
Ü ACBC study was great
success
Ü ACBC is intuitive to
clients and respondents
Ü ACBC will not replace
CBC or other methods
but it will become an
additional tool
So what?
