This mapping diagram builds on the one shown in Figure 1. There are two rows of objects. The first row begins with a large white box, in which is written Malt, Water, Hops, Yeast. The ‘Inputs’ arrow points from this to the ‘Transformation Process’ box, which now also has the label ‘Macro operation’ written beneath it. The ‘Outputs’ arrow leads from this box to another large white box in which is written Beer. There is a narrow black dotted line above the arrows, linking them. It leads from ‘Outputs’, with an arrow head pointing to ‘Inputs’. This dotted line is labelled ‘Feedback’. Bold white lines lead from the bottom left and right edges of the ‘Transformation Process’ box to the mid bottom left and right sides of the diagram. Below this, is another row of objects. The heading for this states ‘Can be broken into’. The row consists of three identical rectangular white boxes. Inside each of the three boxes is a miniature representation of the arrow, rectangular box, arrow mapping presented in Figure 1, the difference being that each of the objects contains no writing or labelling. Beneath the first rectangular box is the label ‘ Micro operation 1’. Beneath the second is the label ‘Micro operation 2’. Beneath the third is the label ‘Micro operation 3’.
