12 | | Most of the methods of usability engineering rely on a proper analysis of the application context. With an increasing size of the application context, such as a larger number of different users, the analysis becomes imprecise. This causes a decrease of the achievable usability for the individual user or a group of users. Furthermore, the users that are actually using the software as well as their way of using the software may differ from the expectations of an initial user analysis. This is because users very often use software also for tasks, for which is was not implemented. As an example, many posters nowadays are created using tools for screen presentations or writing documents as poster software is either rare or expensive. |
