In-class exercise two: Walmart's order packing process Customers can use Walmart's online system to place orders for groceries and household items. An order is packed on the next day. While packing is under way, the customer may want to add or remove items. When the order change request is received, the packing process is stopped. The store checks whether the requested item has been packed or not. If the item is packed, the change request is declined. If not, the store will update the order amount and update the order. Packing resumes right after the request is handled. Assignment: capture the process by using BPMN. Use sub-processes if necessary. No need to use pools/lanes Instruction: save the diagram in either of the following format: an image (.jpg, .png, or gif), MS Word, pdf. Not svg
