Assignment
Exotic Cars Inc. (ECI) is a company specializing in sales and maintenance of the exotic
(hence the name) cars. The cars that ECI sells come from multiple sources: some are shipped
directly from the factories, other purchased from the private collectors, and yet some other cars
are traded-in by the customers of ECI.ECI also provides a regular maintenance service of the
exotic cars, such as engine tune-up, tire rotation, oil change, etc. You do not have to buy a car
from ECI to use its maintenance service; consequently, some owners of the exotic cars
purchased elsewhere also use ECI maintenance service.
ECI appreciates continuing business of its patrons; consequently, the company wants to
maintain as much information about each valuable customer as it possibly can. As a result, ECI
diligently records how much money each customer spends on buying cars (more than a half
have purchased two cars and about third bought three or more), on maintenance service (how
much customer spends overall, and per car), and whether or not a customer ever traded a car
in.
Similarly, ECI maintains detailed data on all the dealers, companies, manufacturers, and other
sources that provide the company with needed services, parts, or cars. ECI is not a "backward"
organization, but things have been done there pretty much the same way since ECI was
founded in 1966. Owners of ECI feel like it is about time not just to move forward, but "leapfrog"
the competition. You have been hired by ECI to find a way of increasing the level of
performance of ECI.

Organizational Structure of ECI
There are three operational locations of ECI; one in Washington, DC, second in
Richmond, VA, and third in Virginia Beach, VA. Corporate headquarters located in
Charlottesville, VA.
Every location has a general manager, which is responsible for authorizing/rejecting
whatever requests area managers of that location may have. Normally, area managers
only handle the issue relevant to their area, for example, sales/trade-in area has its own
manager, body shop/repair shop has its own, and service area has its own area
manager. Every area manager is authorized to make financial decisions up to
$10,000.00. If the amount exceeds the limit of an area manager, then general manager
of that location must authorize it- the general manager has discretion of making
financial decisions of up to $100,000.00. If the amount exceeds this number, a request
is send to the headquarters, where it is approved or rejected by a VP of the area (e.g.,

service, sales, and repair); a VP of the area is authorized to make a financial decision of
up to $250,000.00. If the request exceeds this amount, it must be addressed by the
CEO of ECI.
