Gordon Automotive Repair provides repair services for a variety of vehicle types. They pride themselves on the superior quality and speed of their services as well as the investigative skills of their mechanics. Customers may request a repair service by visiting Gordon's repair shop.

The participants in this process include the Customer as well as Gordon Auto's Receptionist and Mechanic. The process instance is triggered when the Customer requests a repair service.

The process proceeds as follows:

1. The Customer enters Gordon's repair shop and is greeted by the Receptionist.

2. The Customer proceeds to report the symptoms they are experiencing with their vehicle to the Receptionist and requests a Quote for repairs.

3. The Receptionist makes a Preliminary Diagnosis and prepares a Quote of the repair items.

4. The Customer may approve or decline the Quote.

4.1. If the Customer does not provide a decision within 30 minutes, the repair request is cancelled.

4.2. If approved, the vehicle is sent to the Mechanic in the repair department.

4.3. If declined, the Customer leaves the shop with their vehicle, and the repair request is cancelled. The customer also leaves a poor review of the company on RateMyRepairShop.com.

5. When the Mechanic receives the vehicle, he reviews the Preliminary Diagnosis provided by the Receptionist and performs an investigation to confirm the repair items on the preliminary diagnosis as well as to identify additional repair items that may need to be added.

6. Following the investigation, the Mechanic prepares a Repair Report.

6.1. If the Repair Report matches the original Quote, the Mechanic proceeds to fix each repair item.

6.2. If there are new repair items, Repair Report is shown to the customer who may approve or decline it.

6.2.1. If the Customer does not provide a decision within 20 minutes, the repair request is cancelled.

6.2.2. If the Customer declines, the Customer leaves the shop with their vehicle, and the repair request is cancelled.

6.2.3. If the Customer approves the Repair Report, the Mechanic immediately proceeds to fix each repair item.

7. The Customer may request additional repair items be added to the repair report only during the Mechanic's investigation. If the request is received after the Customer has already approved the Repair Report (meaning the Mechanic has already begun fixing the repair items), the new repair items will be considered a new repair request.

8. When the repairs are complete, the Mechanic provides the Repair Report to the Receptionist who uses it to update the Quote and generate an Invoice for the Customer.

9. The Customer may cancel the repair request only while repairs are being completed (not during the investigation). The customer must still pay for any repairs that have already been completed. When the Customer cancels the repair request, the Mechanic provides the repair report to the Receptionist who uses it to update the quote and generate an invoice for the Customer.

10. Once the Customer pays the invoice, they leave the shop with their vehicle and the repair service is considered complete.

NOTE: This assignment tasks the design of a Strategic (Level 1) process model and an Operational (Level 2) process model based on a case description through process analysis. The Level 1 model will describe the process overview using a subset of BPMN notation. The Level 1 model will be extended to a Level 2 model, removing semantic irregularities that may have been present in the Level 1 model and providing all necessary operational details. LEVEL 1 AND LEVEL 2 MODEL ARE BOTH DIFFERENT LEVEL 1 EXTENDED TO A LEVEL 2
