A major travel company would like to develop an information system to improve the operation of their in$-$house telemarketing system to support sales $($TSS$).$ The system will select customers for Telemarketers to call. Telemarketers aim to perform sales of holiday packages. The information system will provide them assistance in serving their end$-$customers $($or potential customers$)$ and will match them with end$-$customers according to their own skills and suitable customers profiles. The system operation is complicated by the varying number and nature of holiday packages offered by the travel company. Before the call is initiated by a telemarketer, the system will also suggest a short list of packages to the telemarketer to talk about with the potential customer.

The system dials numbers automatically according to a customer target list generated by the system. The system retrieves customers details from a database. It then displays the details and provides the telemarketer with guidelines and a script to help in providing an improved service to the end$-$customer. A target list is essentially a list of tuples of the form $.$

One way to improve the call flow rate is to match customers based on sales performance and product knowledge. For example, in selling particular travel packages, the system would do well in matching end$-$customers to telemarketers well informed with appropriate knowledge about the destination and its traditions. For the purpose of this question, assume that a supporting tool to create customer profiles exists, Profiler Tool. A corresponding RM profile may depend on experience and product knowledge. Telemarketers profiles are initialized at hiring. The system will adjust those according subsequent performance Given that there are multiple data streams, the implementation team for the system needs deep expertise in database design. Therefore, a database administrator is needed on the team to develop the system. As a project manager, you decide to hire someone with this specific expertise. Which methodology would you include in the set of methods during your method engineering for the project? explain why.
