Andrea and Karl got married a year ago and are ready to move out of their apartment and into a new home. After looking at several houses, they have developed a list of features that are important to them and that are different among the homes they have visited. The features on their list are called determinant attributes.
The attributes that are very essential for the determination of final choice of buying a good or services are called as determinant attributes. These attributes are considered as an important thing that the buyer ultimately use for purchasing a product and also uses them to compare and differentiate the features of other products or services.
In the example given, Andrea and Karl list a set of features that are very important to them and they compare with the homes they visited. Thus these list of features will be considered as determinant attributes with which they decide the home to which they shift.
