Le Groupe National Dentaire (LGND) has branches in major cities across Cote d’Ivoire such as Abidjan, Grand Bassam, Bouake, Khorogo, Odienne, and Yamoussoukro. The company provides a range of general, complex and cosmetic dental care with specialists offering services in Orthodontics, Endodontics (Root Canal) and Periodontics (oral health and gums).Le Groupe National Dentaire plans to open a new clinic in Man in the west of the country and has rented office units within an old building for its premises. As a result, the company needs to complete some internal work within the building so that it is suitable for patients. The clinic will have three ground floor and two first floor surgical consulting rooms, a patient lounge (first floor), a reception and a storage room. The building is of brick construction externally, with some brick and some stud-partition internal walling. The flooring is concrete.LGND is a high-tech company, and all consulting rooms require networking to a local server. Dental consultants and hygienists view patient information on screens in the consulting rooms. These consist of patient records, including x-ray images, and videos. The patient lounge provides open internet access through an open access PC, and also Wi-Fi for patients’ own devices.The reception has access to an appointment system, which is Windows-based and standardized across the company. It takes electronic payments, sends SMS reminders and emails to patients. The clinic will also be networked to the head office in Abidjan, enabling head office staff to access local server files.The following outline requirements have been identified (excluding specialist dental equipment that connects to the network):a) Overall System Requirements1.
