The prototype is a demonstration of the aims, concepts and technologies used during the
development of the application. It gives a very good approach for the final design. The
navigation map for this demonstration is different to allow users to learn more about the
project and the technology involved:
5.1.6 Usability
Figure 12: Navigation map of the prototype
Usability addresses the relationship between a tool and its user. In order to a tool to be
effective, it must allow the intended users to accomplish their tasks in the best way possible.
The same principle applies to computers, web sites and other software. In order for these
systems to work, their users must be able to employ them effectively.
From the user’s perspective, usability is important because it can make the difference
between performing a task accurately and completely or not, and enjoying the process of
being frustrated. From the developer’s perspective, usability is important because it can mean
the difference between the success or the failure of a system. From a management point of
view, software with poor usability can reduce the productivity of the workforce to a level of
performance worse than without the system. In all cases, lack of usability can cost time and
effort, and can greatly determine success or failure of a system. Given a choice, people will
tend to use systems that are more user-friendly.
