Ms. Mary Bara should study everything the media has already communicated to the public regarding the car faulty engines and the incidents they caused. Bara should not hesitate to address all of these known issues, as the audience will notice these overlooks otherwise and the company would continue to be accused of negligence as a result.
The speech must be delivered in a manner it appeals to the interests of customers and the incident victims alike. An apology must be issued, and there must be assurance that the problems at hand will be resolved with haste as of the end of the speech.
