2016 INFORMATICS INSERT 2

InformUsInformUs is a large marketing company in Melbourne. Bill is the manager of the telemarketing department and he is in charge of all the telemarketers in the company. The telemarketers work between the hours of 5 pm and 8 pm, when more people are likely to be at home. They travel to the office in the late afternoon, log in to the system, download a list of telephone numbers and start making calls to participants to obtain their opinions on various products. Each participant’s responses are written on a paper copy of the survey by the telemarketer.

IssueBill is finding it very difficult to attract and retain telemarketers for the company. He believes that this is because many potential telemarketers do not want to travel into the city each evening for only a few hours’ work. At a recent managers’ meeting, Bill discussed the problem with Mary, the manager of the marketing department. She suggested that Bill look into allowing his staff to work from home via the internet as a way of making it more appealing and to attract and retain telemarketers.

ProposalBill has put together a proposal for setting up a new system that will allow his telemarketers to work from home.Bill’s proposed new system has four main parts:• Telemarketers who choose to work from home will be given a laptop, a headset and a high-speed

broadband connection of at least 12 Mbps for their home internet.• At the start of each shift, the telemarketer will remotely log in to the company network as a virtual private

network (VPN) client and access their list of telephone numbers to call.• Telemarketers will make telephone calls using a voice over internet protocol (VoIP) system through the

company network.• The information collected by the telemarketers will be entered straight into a database via a web-based

user interface. The database will be stored on the InformUs fileserver.

During his research for his proposal, Bill formed a hypothesis: ‘If the telemarketers were allowed to work from home, they would have greater levels of satisfaction. This would lead to higher retention levels (fewer people leaving the company) and fewer sick days being taken. Overall, the telemarketing department would perform better and this would be good for the company.’To get approval for his proposed new system, Bill must demonstrate to the Board of Directors that his hypothesis is well informed and correct. His supervisor has told him that he must have a report regarding his proposal ready for the Board by 23 December. The report will be placed on the company’s VPN for the Board to access and will be password protected.To test his hypothesis, Bill must collect data about whether the telemarketers would prefer to work from home. To do this, he decides to undertake an online survey of all the telemarketers.
