Marketers theorize that consumers’ purchase decisions are driven by the perception of value. This perception, often obtained through a cost-benefit analysis, can be manipulated by adding more features or by reducing the price. This is called the expectancy-value model. Let’s see an example.

Jack, who wants to purchase a laptop, has narrowed down his choices to 4 brands of laptop computers (A, B, C, D). He 1s interested in 5 attributes: Processor Performance (PP), Graphics Capability (GC), Size & Weight (SW), Battery life (BL), & Marked Price (MP) and is evaluating the offerings based on the same. Jack puts 30% priority on Processor Performance, 10% on Graphic Capability, and equal priority on Size & Weight, Battery life, and Price. He comes up with a number called Composite Attribute Value that is the weighted average of the performance of a brand’s offering against Jack’s priorities.

Each attribute is rated from 0 to 10, where 10 represents the highest performance.
