(c) The Johnson-Dunlop Corporation have been hired to design a menu-based
interface to the room booking system for the University. One interview
with the potential users revealed the following:
"Well none of us knows how to use a computer and we're all a bit
scared of them... Oh yes, we've all been doing this for a few years
now and well, basically, we just have busy periods when we book
all of the rooms for the next year. We spend every minute of the
day making bookings. Then it goes quiet for a few months..."
Briefly explain why your user group would be experts, novices or some
blend of the two.
[16 marks, Sample solution]

items in at least two menus. These must enable the user to view all of the
bookings for a particular lecture theatre. You should also be able to add

design that you have produced. In particular, you should link your design
to the comments made in your answer to part (c).
