  2. CHAPTER SEVEN ANALYTICAL ATTRIBUTE APPROACHES: TRADE-OFF ANALYSIS AND QUALITATIVE TECHNIQUES

  3. Trade-Off (Conjoint) Analysis • Put the determinant attributes together in combinations or sets. • Respondents rank these sets in order of preference. • Conjoint analysis finds the optimal levels of each attribute.

  4. Conjoint Analysis Input: Salsa Example Figure 7.2

  5. Conjoint Analysis: Graphical Output Figure 7.3 Thickness Spiciness Color 2 1 0 -1 -2 UTILITY Regular Thick Ex-Thick Mild Medium-Hot Ex-Hot Red Green 0.161 0.913 -1.074 1.667 0.105 -1.774 -0.161 0.161

  6. Conjoint Analysis:Relative Importance of Attributes Figure 7.3 (cont’d.) 0 20 40 60 80 100 % Spiciness Thickness Color 59.8% 34.6% 5.6%

  7. Some Qualitative Attribute Analysis Techniques • Dimensional Analysis • Checklists • Relationships Analysis • There are many others.

  8. Weight Rust resistance Length Color Water resistance Materials Style Durability Shock resistance Heat tolerance Explosiveness Flammability Aroma Translucence Buoyancy Hangability Rechargeability Flexibility Malleability Compressibility A Dimensional Attribute List Figure 7.4

  9. An Idea Stimulator Checklistfor Industrial Products Figure 7.5 • Can we change the physical/chemical properties of the material? • Are each of the functions really necessary? • Can we construct a new model of this? • Can we change the form of power to make it work better? • Can standard components be substituted? • What if the order of the process were changed? • How might it be made more compact? • What if it were heat-treated/hardened/cured/plated? • Who else could use this operation or its output? • Has every step been computerized as much as possible?

  10. Relationships Analysis • Force combinations of dimensions (features, functions, and benefits) together. • Techniques: • Two-dimensional matrix • Multidimensional (morphological) matrix • Two-dimensional example: person/animal insured and event insured against. • Household cleaning products example used six dimensions: • Instrument used, ingredients used, objects cleaned, type of container, substances removed, texture or form of cleaner

  11. Other Methods:Lateral Search Techniques • Free association • Stereotype activity • Lateral thinking -- avoidance • Creative stimuli words • Studying “big winners” • Use of the ridiculous • Forced relationships

  12. Lateral Thinking -- Avoidance Keep an idea from dominating thinking as it always has in the past by asking avoiding questions. • Ask “Is there another way of looking at this?” • Ask “Why?” • Focus on an aspect of the problem other than the “logical” one. • List all possible alternatives to every aspect of the analysis. • Break apart aspects (concepts) of the problem, or combine them to create even more concepts.

  14. Use of the Ridiculous • How can you join two wires together? • Hold them with your teeth. • Use chewing gum. • Can you think of others? • Do any of these ridiculous ideas suggest a not-so-ridiculous solution?
