6Some Product Design Questions
Should we offer our business travelers more room
space or a fax machine in their room? Should we
offer more leisure-time activities (sauna,
exercise room, tennis courts) or more food
related services (several dining options, vending
machines, in-room kitchen facilities)? Should we
use a steel or aluminium casing to increase
customer preference for our new extrusion
equipment?
7What is Conjoint Analysis?
- A way to incorporate the structure of customer
preferences into the new product design process.
It helps evaluate how customers make tradeoffs
between various product attributes (a
decompositional approach). - The basic outputs of conjoint analysis are
- A numerical assessment of the relative importance
each customers attaches to attributes of a
product set. - The value (utility) provided to each customer by
each attribute option.
8Use of Conjoint Analysis
- Designing new products that enhance consumer
utility. - Forecasting sales/market share of alternative
product concepts. - Identifying market segments for which a given
concept has high value. - Identifying the best concept for a target
segment. - Pricing products/product bundles.
- Product line management.
- Positioning new products to different segments.
9Product Design Conjoint Analysis
- The approach derives customers utility values
for attributes and attribute options based on
customers stated overall preferences for
different bundles of attributes. The following
example shows Memory and Price bundles.
PriceMemory 1,000 1,500 2,000 8
Mb 4 2 1 16 Mb 7 5 3 24 Mb 9 8 6 9 Most
preferred 1 Least preferred

11How to Use inDesign/Tradeoff Evaluation
- Example 24 Mb vs 16 Mb 7.7 5.0 2.7 units
- 1,000 vs 1,500 6.7 5.0 1.7 units
- So D 8 Mb is worth more than 500 to this
customer. - 2.7
- ( _at_ (1,500 1,000) _at_ 795)
- 1.7
- Can use to assess value to customer of
non-product (service) attributes.

where P a particular product/concept of
interest, U(P) the utility associated with
product P, aij Utility associated with the jth
level (j 1, 2, 3, . . . , ki) on the ith
attribute (part-worth), ki number of levels of
attribute i, m number of attributes,
and xij 1 if the jth level of the ith
attribute is present in product P, 0 otherwise.
19Market Share Forecast
- The relevant market consists of products P1, P2,
. . . , PN. Some of theses may be existing
products and, others concepts being evaluated. - Each consumer will prefer to buy the product with
the highest utility among those available. - Then forecasted market share for products Pi is
given by - K Consumers who prefer i

the market share for each product is 1/3. - Frequently purchased productsExample If
consumers buy their most preferred brand 80 of
the times, and their second most preferred brand
20 of the times, then the market shares for the

25Situations Where Conjoint Applications Might Be
Valuable
- The new concept involves important tradeoffs
affecting design, production, marketing, or other
operational variables. - Product/service is realistically decomposable
into a set of basic attributes. - Product/service choice tends to be high
involvement. - Factorial combinations of basic attribute levels
are believable. - Desirable new-product alternatives can be
synthesized from basic alternatives. - Product/service alternatives can be realistically
described, either verbally or pictorially.
(Otherwise, actual product formulations should be
considered). - Perceptions of hypothetical combinations are
reasonably homogeneous across members of the
target group.
26Conjoint Study
Stage 1Designing the conjoint study Step
1.1 Select attributes relevant to the product or
service category, Step 1.2 Select levels for
each attribute, and Step 1.3 Develop the
product bundles to be evaluated. Stage
2Obtaining data from a sample of
respondents Step 2.1 Design a data-collection
procedure, and Step 2.2 Select a computation
method for obtaining part-worth functions. Stage
3Evaluating product design options Step
3.1 Segment customers based on their part-worth
functions, Step 3.2 Design market simulations,
and Step 3.3 Select choice rule.
