QUESTION 3 [10 marks] It was decided that during the RS project, prototyping will be used to gain knowledge and reduce uncertainty. Explain (i) how and (ii) during what stage of a system development project, would prototyping be useful as a means of reducing the following uncertainties: 3.1 There is a proposal that the senior managers at Healthy Food have access to management information through an executive information system installed on personal computers located on their desks. Such system would be costly to set up and there is some doubt about whether the managers would use the system. Explain (i) how, with a made-up Healthy Food example (3 marks) and (ii) during what stage of a system development project (2 marks), would prototyping be useful as a means of reducing this uncertainty. (5 marks) 3.2 Healthy Food is considering implementing a telephone system using the system development features supplied by Microsoft Access. They are not sure whether it can provide the kind of interface that would be needed and are also concerned about the possible response times of a system developed using Microsoft Access. Explain (i) how, with a made-up "Healthy Food example" (3 marks) and (ii) during what stage of a system development project (2 marks), would prototyping be useful as a means of reducing this uncertainty
