Conclusion
             
              In 
                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 
                study. 
              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.
