HOTSPOT -
An online retailer creates a case type that processes and manages customer orders. The checkout process has four steps:
1. Review Order: The customer reviews the items in order of add-to-cart selection and can adjust the quantity of each item and delete items to calculate and display the order total.
2. Select Shipping Option: The customer selects a shipping option to determine and display the shipping charge for their order.
3. Enter Delivery Address: The customer enters their delivery address to determine the sales tax, if applicable, and the application displays the calculated sales tax.
4. Enter Payment Information: The customer selects a payment option and confirms the grand total of the order.
For each calculation, identify the appropriate chaining option to maximize the performance.

As it is for performance, anything that do not need to show value immediately can be backward. Forward only to get the real time value immediately.

why is shipping charge backwards chained? I thought that shipping cost is dependent on the types of items, amount, as well as what the customer selects (i.e. forward chaining).
