Approach to Prediction • Compensatory Models Seek an overall score for prediction of choice • Non-compensatory Models assume a decision in the process of evaluation
All Models Start With The Premise That if a product is scored best on all attributes by a customer then it will be purchased by that customer That is to say: The Dominance Model Of Choice is Universal
Brand X is the dominant choice because it is best on all attributes. BRAND A BRAND B BRAND C BRAND X STYLE 30% 1 2 5 6 POWER 20% 6 3 4 7 Capacity 15% 3 4 2 5 COMFORT 35% 5 6 4 7
When there is no dominant brand, then Compensatory explanations

Types of Non-compensatory Models • Conjunctive • Must meet a minimum level on all attributes or drop • Disjunctive • Be greater than a specific level on a few of the important attributes • Lexicographic • Highest on most important attribute, go to second most important attribute only to break a tie.

Why Is this Basic Model so popular? • Forces us to be explicit about advertising/product decisions • It allows us to think about probabilities of purchase and using them as a measure of intention strength • Use the probabilities in pricing and market share
Basic Weakness of The Compensatory Model • Weights are constant, beliefs are stable • Attributes are constant across products and across usage situations. • Attributes are not necessarily independent • safety & power, quality and price, • “Bigger is always better” • Evaluation and Articulation are not the same. • New products can cause new dimensions
Not Weaknesses of ModelWeaknesses • There is nothing statistical about the model per se. (no statistical weakness.... sample size etc. • Failure to include an attribute is not a weakness of the model (zero weight) • “You don’t know if the model has the right attributes.” • Using wrong model is not a weakness of the model (wrongly used lexicographic) • Subjectivity is not a weakness! Lack of consistency is a potential problem.
Implications for Changing Strategy • Modify the product (real positioning) • Alter beliefs about amount of attributes • Alter beliefs about competitor’s amount • Alter importance weights • Call attention to neglected attributes • Shift the buyers’ ideals

Probabilities of Purchase • Highest value takes all the market? Unrealistic! • A high score reflects a high probability of Purchase is more realistic • A probability of purchase on an individual basis implies a market share percentage over the total market
What is the market share that is anticipated for each of the four brands?

The Average % Score for the Four brands is? • 1/N = ¼ = 25% • Relative Quality Score = Brand Score/Average • Relative Quality for Brand A = 24.58%/25% • Relative Quality for Brand A = 94.32%

The Maximum Price for Brand D • The average price in the market for the four Brands is $200 each • IF the price is set to reflect relative quality, then what is the most that Brand D can charge • Brand D has a 107% of the averagequality, It can charge a maximum of 107% of the average price! • Brand D’s price = 107% x $200 = $214
# 2 If everything in your marketing mix is identical to the competitor’s mix • There is a total of Five firms in the industry • What is the average market share? • 1/N = 1/5 = 20% • What is you market share? • 20%
#3 If everything in your marketing mix is identical to the competitor’s mix • Except Your Relative Product Quality is 120% above the average. • There is a total of Five firms in the industry. • What is the average share? • 1/N = 1/5 = 20% • What do you expect your market share to be? • S = 1.20 x 20% = 24%
#4 If everything in your marketing mix is almost identical to the competitor’s mix • Except Your Relative Product Quality is Ur =120% above the average. • What do you expect your relative market share to be? • Ur = Sr = 120% • However your relative share is actually measured to be 108% • How efficient, E, is your marketing system at converting Relative product quality into Relative market Share • Sr = E x Ur • Sr = Sr/Ur x Ur • Sr = 108%/120% x Ur • Sr = 90% x Ur • E = 90%
#5 If everything in your marketing mix is identical to the competitor’s mix • Except Your Relative Product Quality is 120% above the average. • The average price in the market is $300 • What is the highest price you can charge based on your relative quality • P = 1.20 x $300= $360
#6 If everything in your marketing mix is identical to the competitor’s mix • Except Your Relative PRICE is 150% above the average PRICE • The average price in the market is $300 • WHAT PRICE ARE YOU CHARGING • P = 1.50 x $300= $450 • WHAT RELATIVE MARKET SHARE DO YOU ANTICIPATE? • NOT 150% OF AVERAGE • Sr = 1/Pr = 1/1.50 = 66.67% of the average share
Market Share Theorem • Predicts Your Relative Market Share based on your Relative Marketing Effort. • Your relative product quality is 120% • Your relative price is 150% of average • What do you predict will be your relative market share? • Sr = Ur x 1/Pr • Sr = Ur/Pr = 120%/150% = 80% of the average
Any Questions on • 1) The use of Relative Quality to predict Relative Market Share • 2) The use of Relative Quality to set a selling price • 3) The Use of the Relative Quality and Relative Market Share to measure conversion efficiency • 4) The Use of Relative Value as the Inverse of Relative Price to Predict Market Share
