CASE STUDY: YOUTIGER WASTE MANAGEMENT LTD. YouTiger Waste Management Ltd (YTWM) is Zoomlion's main competitor in waste management solutions in Ghana. YTWM is in the business of collecting. transporting and disposing of waste materials (only solid and liquid waste, but no gas). Other services include the managing and monitoring of waste materials. YTWM focuses on residential users and small commercial businesses and is in 6 of the regions of Ghana. The solid and liquid waste are residential; non-hazardous commercial and industrial waste. YouTigerWaste Management Ltd is registered to dispose of or re-cycle the waste it collects in 10 Landfill sites; 3 glass and bottle collection depots; and 2 vegetation incinerator plants. Waste disposal at Landfill sites is common practice as this is a relatively inexpensive method of disposing of most waste materials. Incinerator plants is a controversial method of waste disposal and is relatively more expensive than Landfill even though it needs less space. The glass collection depots actually give credit to suppliers of glass waste as this waste is re-cycled YTWM is the most competitive of all Waste Management business and is into leading edge technology. YTWM supplies three different types of dustbins (red, green and black) to each of its clients, each dustbin has a microchip attached either at the base or side of the. The waste type in the three dustbins is defined as follows: the red dustbin is for plastics and metals (tin cans); the black dustbin is for glass, bottles, etc.; the green dustbin is for vegetation (i.e., grass, flowers, branches etc.). YTWM has a strict policy if clients do not adhere to the separation of waste in the specific dustbins, they face immediate penalty charges and if the client still persist with this problem the client's contract with YTWM could be cancelled. It is important to note there are separate trucks for each of the three different waste types in the three different colour coded dustbins. YTWM wants a system that would make administration of its ever-expanding client base easier and faster. A User Specification has been drawn up below, the system should: 1. Allow maintenance of customers new and old. 2. Allow tracking on waste collection profile for each customer. (If customer contacts the support desk and complains about waste not collected over a period of time this can be tracked) 3. Automatically calculate a charge back facility to each customer monthly based on: a. Weight and type of waste each customer has in each of their dustbins b. Penalty charge if the wrong waste types are in the wrong dustbins, or waste types not separated. e Number of each type of bin as its possible for a customer to have 3 red bins 2 black and 1 green bin. Answer the following questions; a. A consultant was contracted to draw up a feasibility report on YTWM project, discuss two possible technical problems you could envisage with this project. b. What are the main functional requirements of the YTWM system? Identify any ambiguities in the user spec. c. Discuss the methodology you will employ for the development of the system and why you choose to use that methodology. d. Draw an ERD (entity relationship diagram) for the YTWM system
