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.
