OWM is the most competitive of all Waste Management business and is into leading
edge technology. OWM 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.). OWM
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 OWM 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.
OWM 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:
Allow maintenance of customers new and old.
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)
Automatically calculate a charge back facility to each customer monthly
based on:
Weight and type of waste each customer has in each of their
dustbins.
Penalty charge if the wrong waste types are in the wrong dustbins,
or waste types not separated.
Number of each type of bin as its possible for a customer to have 3
red bins 2 black and 1 green bin.
