- Abstract
- Die Studie untersucht die Usability der Homepage des Landtags NordrheinWestfalen. Es wird analysiert, wie benutzerfreundlich die Website ist, ob sie effektiv genutzt werden kann und ob die Inhalte der Site den Erwartungen der Benutzer entsprechen. Drei Evaluationsmethoden finden Einsatz: Ein Thinking-Aloud-Test, eine heuristische Evaluation und eine Availability-Untersuchung. Der hier eingesetzte Thinking-Aloud-Test ist ein Benutzertest, bei dem zwanzig Laien und zwanzig Information Professionals zuerst ihre Erwartungen an die Site äußern und dann anhand der Homepage, unter Beobachtung, Aufgaben bearbeiten. Anschließend geben sie anhand eines Fragebogens eine Beurteilung ab. Die heuristische Evaluation ist eine expertenzentrierte Methode. Usability-Experten stellen Checklisten auf, anhand derer eine Homepage untersucht wird. In dieser Studie finden drei Heuristiken Anwendung. Die Availability-Untersuchung der homepageeigenen Suchmaschine ist eine bibliothekarische Evaluationsmethode, die anhand einer Suche nach Webseiten, von denen bekannt ist, dass ihr Angebot aktiv ist, die Qualität der Suchmaschine hinsichtlich der Erreichbarkeit der Dokumente bestimmt. Die drei Methoden ergänzen einander und decken in ihrer Variation einen großen Pool an Usability-Fehlern auf. Die Ergebnisse: Die Benutzer vermissen auf der Homepage besonders Informationen über den Landeshaushalt, eine Liste der Mitarbeiter mit ihren Zuständigkeiten, Hintergrundinformationen zu aktuellen landespolitischen Themen und Diskussionsforen als Kommunikationsmöglichkeit. Im Durchschnitt liegen die Klickhäufigkeiten für das Lösen einer Aufgabe über denen, die für den kürzesten Weg benötigt werden. Die Abbruch-Quote aufgrund einer nicht lösbar erscheinenden Aufgabe beträgt bei 40 Probanden à sechs Aufgaben 13,33% (32 Abbrüche). In der Abschlussbefragung äußern sich die Testpersonen größtenteils zufrieden. Die Ausnahme stellt der Bereich "Navigation" dar. 40% halten die benötigten Links für schwer auffindbar, 45% aller Probanden wissen nicht jederzeit, an welcher Stelle sie sich befinden.
