SONCAS is a French acronym for Sécurité - Orgueil - Nouveauté - Confort - Argent - Sympathie. Well known in France, this system was invented to know what motivates a person to buy a product. After the research of a French study it was found that most people are driven by one of these six topics Sécurité - Orgueil - Nouveauté - Confort - Argent - Sympathie[1] that could be translated to Security - Vanity - Novelty/Technology - Comfort - Money - Likeability.
This technique is used by sellers to find what motivation a buyer requires to make then buy the product.[2] [3] Another way of using SONCAS is to use every single point to cover all six topics to be sure to make the customer like the product.[4]
SONCAS is also linked with the Enneagram of Personality and Maslow's hierarchy of needs.[5]
