Natura has to fill 7 orders for its clients. He requires placing the required product in work boxes and subsequently closing them properly so that the product reaches the customer correctly. The process consists of filling the box and later closing it. As the content of each box and the size of these is different, the filling and closing times of each order is different. These times are shown in the table below. Orders Place in box (minutes) Closing Box (minutes) 1 9 6 2 8 5 3 7 7 4 6 3 5 1 2 6 2 6 7 4 7 a) Find the sequence to complete the orders in the shortest time possible. b) Using a Gantt chart, find the total time in which all orders will be completed using the sequence from part a.

The sales department receives all orders from the customers. While receiving the order, the sales team authorizes the payment and check line items. If authorization is failed, a cancelation message is sent to the customer. On the other hand, each line item is checked with the stock. If it is in stock, assigned to the order otherwise the item is removed from the list. If stocks are available for all products and payment is authorized, the sales team dispatched the order.Shipping teams ship the order to the customer. The method of delivery is decided conditionally. Depending on the condition either the Urgent Delivery activity or the Regular Delivery activity is performed. The delivery procedure is finished when the customer receives it and signs in. Draw an Activity diagram based on the above scenario.
