BoothCater, a small catering business, provides custom meal services for local events and parties, such as the lunch for workshops at Booth School of Business. BoothCater can now receive orders through different channels such as phone calls, walk-ins, and online orders. In order to guarantee prompt order fulfillment and customer satisfaction, the owner has established a standard process to handle orders at frequent intervals during the day. Following this, each order has two steps to process: the first is to prepare the meals, and the second is to package them according to the delivery or pickup option chosen by the customers. These steps are always done in this order. Currently, there is only one staff member at each stage: the kitchen staff Alex is responsible for preparing the meals, and the packaging staff Jane packages the meals. Alex can prepare an order in 8 minutes on average, and Jane can package an order in 5 minutes on average. They work independently to complete their tasks
