Produce the class diagram follow the B-C-E rules for the case study
CASE STUDY : CAR SERVICING CENTRE A car service centre undertakes routine servicing and repair work on most car models. It employs a Centre Manager, several Mechanics, one Customer Service Staff and one Finance Staff. Due to the limited manpower, the centre intended to set-up a computer-based information system to keep track of all the workshop's various ongoing activities. The system is expected to facilitate and improve productivity of all employees. Currently, Customer Service Staff handles service request made by customer through phone and send a quotation via email. If the quotation is agreed, customer will make slot booking by confirming date and time of service, together with car and owner details. The Customer Service Staff will then block the slot for the customer if it is available or recommend another slot. If the quotation is not agreed, the customer may opt to cancel request or ask for a revised quotation. Every customer will be called to remind them of their booking a day before the service schedule. Occasionally, the centre may receive emergency case. For this situation, Customer Service Staff will get details from car owner and find an available slot for servicing or repairing job. A Mechanic is assigned to assess the condition of the car and report on the type of breakdown or damage identified. Quotation is then prepared by Customer Service Staff and given to customer. The Customer Service Staff prepares invoice after each service is completed. Customer will then pay at the payment counter and Finance Staff will record the payment made to close the service transaction. Before starting their work each day, each Mechanic is given service files with list of servicing tasks booked for the day. They record and update each work done in the service files after completion. While servicing customer's car, the mechanic may report on any spare parts that are running out of stocks. However, when there is emergency case, some of them will need to check the condition of car and report to Customer Service Staff. Centre Manager will order spare parts after checking on the report made by Mechanics. He is also the one who will handle payment after receiving the invoice of delivered spare parts from the supplier.
