Comments

  • Please note that the amount of participants for Impress does not suffice to produce significant results. Hence, be aware when making conclusions that the data reflects merely a trend.
  • The fact that each application has a different amount of participants is due to the organizational structure and the tasks of the work force inside the company this survey was distributed in

Discussion

  • There are two categories that are somewhat better rated than the rest. Controllability and conformity with user expectations seem to cause fewer problems among users in this context. This might be due to the fact that there were almost no novice users; some even participated in workshops and trainings, although that turned to be insignificant when related to average ratings.
  • Overall, according to the quality of OOo as users perceive it, all three applications have substation opportunities for improvement. Most of all, the categories "suitability for the task" and "self descriptiveness" are perceived as of less quality. This might indicate that the applications of OOo that were subject to evaluation do not cover the needs as required by this context and the tasks. In addition, users seem to have difficulties in understanding the things the applications present them via the interface e.g. string, icons, feedback etc.
