the introduction, to this dissertation, I indicated that my goal
was to evaluate usability in a 'methodical, concise and readable
way'. I hope that I have, not only, achieved this but that I have
done it in a way that has made the journey from cover to cover
an enjoyable one for you, the reader.
I have attempted to establish what
usability is, how it can be measured and why its importance should
be appreciated when designing interactive systems. I have explored
the numerous models, theories and themes that abound the arena
of usability and have given illustrations that acknowledge their
application in the real world, concluding with the Reuters case
Finally, I have above all, tried
to stress the important role that the user can play in the development
of systems and as a consequence why, in the "man-machine
interface" [Grandjean 1988], the user must not be neglected.
