You should approach the design question of your choice in the following manner: Analysis Produce an analysis of the given situation/problem, which may be in written or graphical form. [5] Specification From the analysis produce a detailed written specification of the design requirements. Include at least five specification points other than those given in the question. [5] Exploration Use bold sketches and brief notes to show your exploration of ideas for a design solution, with reasons for selection.
