Generally, a client is treated as an isolated target, as a single decision maker who makes his or her own decision. But who influences his choice? In quantum physics, we talk about the intrication of particles between them. This means that any change in the state of one instantly changes the state of the other, no matter how far apart they are. When applied to marketing, we can talk about intricate influence. This influential marketing takes the form of measuring the maturity of the customer as a whole, including all decision-makers, users, family members or buyers involved in the choice.
