Question 2 Prototyping, which is usually a quick functional model of the system design, is exposed to the users. In our case the students who are expected to be the main users of the software are presented with the prototype for a period of time and they report back give feedback on their experiences. Problems are then identified in real time and any requirements that may have been left out noted. The prototype is then reviewed and the difficulties experienced by the target users rectified. Loopholes in the system are identified and requirements left out incorporated. A brainstorming session, designed to come up with ideas, possibilities and solutions to problems can be a good requirement gathering technique. Stakeholders, such as programmers, managers and the potential users form a think tank. Issues such as how best to present the bookstore’s catalog of items online for example can be visualized. Payment modes and delivery modalities can be born and nurtured in such sessions. Survey tools such as a questionnaire can be used to collect relevant pieces of data that can be help in the requirement gathering process. Use of well-structured questionnaires, designed to give the desired information, such as preferences in design techniques, best payment modes, delivery schedules and so on, can play a vital role in requirement gathering processes. …
Members present can identify problems and suggest solutions to these problems. For example, if a student (who is a potential user of the system) can highlight some of the problems encountered by the current system used by the bookstore, such as time wasting, members can come up with suggestions such as introduction of delivery mechanisms that are time conscious. In the process, requirements may be gathered. Question 3 This system is designed to meet the special accommodation needs of individual students by offering a variety of options based on pricing, location and facilities available to them. On the other hand, hostel owners can provide description of the properties they own by contacting the university’s administration. This system offers advantages for both the students, premise owners and university administration. For students, they are provided with a platform to search from a variety of available hostels and choose those best suited for their individual needs. This saves them time and makes it easier to compare the various hostel listed in the database. For the hostel owners, advertising is catered for and therefore cut down on their operational expenses. Finally, the school administration enhances their accommodation needs for their students and helps them monitor the whereabouts of the students. This enhances their mandate to ensure protection of enrolled students. However, the systems could be made even better by enabling online rent payments by students and providing actual photographs of the various listed hostels for the students to view.
