You are tasked to design a new ACC System $($Automotive Customer Care$)$ for a car repair garage. Below are the workflow that you need in order to build the system for the client. Draft a UML Use Case Diagram that will solve and be compliance with the client's need. In order to use the system, a mechanic will have to log into the ACC System with his$/$her employee ID and password. This enables the ACC system to keep track of the mechanic$$s work log$.$ The mechanic uses another system, the Onboard Automotive Diagnostic $($OAD$)$ Handheld System to scan and diagnose customer vehicles for mechanical problems. The OAD Handheld System generates a diagnostic report and exports the report back to the ACC System via WIFI. Hint: The user is using an OAD System to execute a function $($generate diagnostic report$)$ to be exported to the ACC System. We are designing the ACC system and not the OAD System, therefore the OAD System should be an external actor and not another System that you are responsible to design.

The mechanic reviews the diagnostic report and based on his expertise and experience, may overwrite any specific item$/$s in the report if necessary. The mechanic will then use the ACC System to generate an official final diagnostic report and the recommended repair solutions. Next, the mechanic will consult with the customer to determine their action plan $($which repair$/$s that the customer is wanting to fix$).$ Once the customer has decided on an action plan, the mechanic will use the ACC System to generate a work invoice. The work invoice contains all the itemize repairs and their related cost. Finally, after the customer$$s vehicle is fixed, the ACC System will save all repair information on its own database for future reference.

Design the UML Use Case diagram with MS Visio for the ACC System above.
