RetroMotorcars is a small company located in the Eglinton suburb of Derry. The company specializes in finding and selling European classic cars and parts which might be considered difficult to source, ranging from relatively recent classics, such as the Jaguar XJ6 to much older vintage cars no longer in production, such as the Porsche Speedster. It also sells the full range of Haynes car guide manuals, including rare copies of many classic car guides. It is considering extending its product range to include items which are not as rare as its cars and parts, possibly to include compatible sound systems, mp3 players, wind deflectors, generic spare parts, and so on, as well as items of memorabilia associated with classic marques, such as mugs, scarves and key rings. Although it is a small company, it has ambitious expansion plans, hoping to open a second outlet for processing orders in the North West within the coming year. Most of its sales come through paper-based brochures and advertising in the press, but it would also like to extend its catalogue so that customers could at least browse online. Most of the orders are taken in-house by order entry administrators, although some sales also come from third part commercial organizations. There are also administrators working in the areas of billing, shipping, packaging, and customer service. Their order entry and billing system has outlived its usefulness, and the Managing Director realizes that the system will have to be brought up to date in order to keep pace with the company’s development plans. Your team has been brought in to analyse the existing system, identify opportunities for improvement and develop the concept for the to-be system.
