<p>The client was using a rule-driven product placement (RDPP) approach on its e-commerce website to sequence products. In this approach, pre-defined rules were used to calculate a score for each product based on a formula that determined the sequence. The formula assigned weights to different behavior metrics, including previous sales, product price, inventory on hand, etc. The e-commerce experts had to assign the weights to these metrics based on their experience.</p> <p>In this state, the whole process was dependent on human judgment. The entire process was stagnant and irrelevant because of changing customer behavior. The client wanted an intelligent and dynamic method based on data rather than human judgment to assign weights to different metrics dynamically and avoid human error.</p>
