It is a functionality to predict and display the actual delivery date when a shipment is expected to arrive in the customer’s hand when an order is checked-out on the client's website. 
This algorithm will be derived from multiple tasks and logistic actions from the time an order is check-out - Processed - Shipped - Delivered. For every item in a check-out bag, the delivery date will be displayed for the customer. This functionality will be rolled out first as MVP and then after training and analytics, will be deployed in a phased manner for all product categories.
