For review, “dark testing” is A/B testing on Facebook conducted by 1) building multiple variations of a single post by adjusting the message, thumbnail, image, etc., 2) serving these variations to different, similar audiences, and 3) measuring performance and designating a “winner.”
The amount and nature of value in a particular product or service always lie in the eye of the beholder, of course. Yet universal building blocks of value do exist, creating opportunities for companies to improve their performance in current markets or break into new ones. A rigorous model of consumer value allows a company to come up with new combinations of value that its products and services could deliver. The right combinations, our analysis shows, pay off in stronger customer loyalty, greater consumer willingness to try a particular brand, and sustained revenue growth. We have identified 30 “elements of value”—fundamental attributes in their most essential and discrete forms. These elements fall into four categories: functional, emotional, life changing, and social impact. Some elements are more inwardly focused, primarily addressing consumers’ personal needs. For example, the life-changing element motivation is at the core of Fitbit’s exercise-tracking products. Others are outwardly focused, helping customers interact in or navigate the external world. The functional element organizes is central to The Container Store and Intuit’s TurboTax, because both help consumers deal with complexities in their world.
