Assignment title: Information


PKL Autoparts supplies automotive parts to mechanics, dealers and lately to the mining industry. There are 4 offices and 1 warehouse from where all stock is sourced. Currently the inventory system located at the warehouse is accessed on expensive fixed 512Kbit lines. They are geographically spread out as per this map (Not to Scale). These are in Hillarys, Osborne Park (being the main warehouse), Alexander Heights, Kewdale and Melville. PKL Autoparts has recently had some issues and you have been assigned by your boss to assess and report on resolution strategies for the customer. The 4 stores generate a base turnover of $100 million per year with 150 employees. Over 50% of business revenue is from credit card transactions. The tills in the Osborne Park (main store) use wireless connections to communicate to the computer network. The computer network is entirely wireless based as the business is in a heritage listed building. The Alexander Height store has a wired computer network but has wireless connectivity for the tills. Both stores network via wireless link to the Osborne Park warehouse for inventory. In addition, each store has an access point so that the staff at each store can use handheld devices (PDAs) to take inventory, and another Access Point (AP) so that managers can use laptops in their office. The incident Last month, the company had to sack its IT Administrator for accessing illicit material (pornography) after her 3rd warning. The administrator became hostile and had to be ejected from the premises by the police. Later that afternoon the network for the Hillarys shop became unserviceable. This continues to intermittently happen now for both stores Kewdale and Melville. Connectivity to the Osborne Park inventory is reliable but there are now errors in shipment because of an untraceable error. Orders arrive in 2 | P a g e correct order but when the automated deliveries are sent out quantities are wrong for 60% of orders causing massive restocking costs and loss of reputation. The owner believes that the ex-IT Administrator is behind this as she was responsible for the commissioning of systems and the wireless links. Police have been unable to respond or provide any detail. The person supporting the issue with the SQL inventory system has been unable to provide any data to explain the shipping errors. The account passwords and other traces of the old IT administrator have been cleansed from the system.
