For an Assistance Request case, when users enter the vehicle make, one or more associated models display in the Model drop-down. Intermittently, users report that during the Submit request process, when entering the vehicle information, some car makes do not have an associated model name in the drop-down. Stakeholders need to easily identify the vehicle makes without at least one associated model.
In addition, stakeholders are concerned about application performance. To ensure customers can complete assistance request cases efficiently, stakeholders require that the vehicle model list is generated within 200 milliseconds.
The following table provides the credentials you need to complete the challenge.
