Automated Transportation, Inc. is a medium-sized manufacturer of remote-controlled cars, boats, and drones. The company was established five years
ago when two
others decided to build and sell remote control cars to enthusiasts. As the company grew, they expanded their product offerings to
include remote control cars, boats, and drones. The
others serve as the president and CEO of the company, and they now have over 70 employees.
They have two key customer groups, ho
yists and businesses interested in incorporating drones into their business process and supply chain. These two
customer bases provide a variety of opportunities for growth. Management values internal control, but since they are busy running the company they
have employed accounting personnel to help design the company’s processes, policies, and internal controls:
The company is not required to have a report on internal controls and external auditors are not required to attest to the company’s internal controls.
However, the owners want to be sure the company employees are designing and following policies that will help them maintain efficient and effective
operations.
The owners are also very data-driven and make many of their business decisions only after considering the data collected and analyzed.
The following is an excerpt from the data dictionary designed by the company’s information systems personnel and accounting information systems
accountants.
