1. Examine the flow process chart in the figure and try to develop an improved method for the future, taking advantage of the technologies becoming available.
Answer: There are many possibilities, but here is one (see figure) that we have developed for future consideration. We do not consider it to be feasible yet, because of the inconvenience for the markers having to read from screens and having to add comments by keyboard. However, when 'electronic paper' and stylus based mark-up become common, we hope to pilot this approach.
Notice that, in addition to the reduction in the number of activities involved, physical transports have been replaced by electronic, and the original, purely sequential process has been replaced by one with parallel paths. The electronic mode of operation should also allow the automatic generation of prompts when the deadline for return of marks approaches.
