Case Study Scenario Exotic Cars Inc. (ECI) is a company specializing in sales and maintenance of the exotic cars. The cars that ECI se lls come from multiple sources  Shipp ed directly from factories  Purchas ed from private collectors  Traded -in by 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 elsewher e also use ECI maintenance service. ECI appreciates the continued business of its patrons. C onsequently, the company wants to maintain as much information abo ut each valued customer as possible . As a result, ECI diligently records how much money each customer sp ends on buying cars (more than 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 mai ntains 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. The o wners of ECI feel like it is about time not just to move forward, but “leapfrog” the competition. You, along with the members of your team, have been hired by ECI to find a way of dramatically increasing the level of performance of ECI. Organizational structure of ECI There are thre e operational locations of ECI  Washington, DC,  Richmond, VA,  Virginia Beach, VA. The c orporate headquarters are located in Charlottesville, VA. Every location has a general manager who is responsible for authorizing/rejecting requests area managers may have. Normally, area managers only handle t he issu e relevant to their area. F or 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 are a manager, then the general manager of that locat ion 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 the VP of the area (e.g., service, sal es, and repair).
