Web accessibility

Abstract

In dieser Arbeit wird erstmalig ein holistischer Ansatz zur Ermittlung der betriebswirtschaftlichen Implikationen von barrierefreien Webpräsenzen vorgestellt, welcher die Barrierefreiheit aus zwei Perspektiven (Organisation, Behörde) analysiert. Die organisationale Dimension umfasst die Entwicklung eines fallstudienbasierten Rahmenwerks für eine explorative Analyse der betriebswirtschaftlichen Implikationen von Barrierefreiheit sowie dessen Anwendung auf Organisationen in drei verschiedenen Unternehmenssektoren: Tourismus, Finanzdienstleistungen und Information. Die Ergebnisse dieser Fallstudie stellen einen ersten betriebswirtschaftlichen Ansatz dar, um die wirtschaftlichen Implikationen von barrierefreiem Web zu identifizieren und dienen somit als wichtige Entscheidungsunterstützung für das Management. Die wiederholte Anwendung dieser Methode führt zu einer beliebig erweiterbaren Fallstudiensammlung, welche eine wichtige Basis für weitere quantitative und qualitative Forschung bildet. Die behördliche Dimension dieser Arbeit untersucht ausgewählte Strategiealternativen zur Etablierung eines einheitlichen Web Accessibility Gütesiegels in Österreich. Dafür wird ein antizipativer Ansatz verwendet, welcher das Bestehen eines normativen Dokuments und einer Evaluationsmethodik voraussetzt. In einer Szenarienanalyse werden vier Strategiealternativen entwickelt und evaluiert. Ferner wird ein flexibles Geschäftsmodell für ein österreichisches Gütesiegel entwickelt, um in weiterer Folge Entscheidungsträger bei der Auswahl einer geeigneten Herangehensweise auf nationaler Ebene zu unterstützen und somit eine europakonforme Realisierung eines Gütesiegels unabhängig vom Fortschritt internationaler Standardisierungsbemühungen zu erleichtern.

This thesis develops a holistic approach for the analysis of business implications of accessible web presences which encompasses two strongly interrelated perspectives (organization and authority). The organizational part introduces a case study research based framework for an exploratory analysis of web accessibility implications which is applied to organizations in three business sectors. The case study draws on a triangulation approach and considers the opposing insights of organizations with and without successful web accessibility implementation in the tourism, financial services and information sector. The findings of this case study research constitute a first managerial approach to identify the business impacts of web accessibility and generate a sound basis for management decision recommendations. The reapplication of this methodology to any real world case results in a case study collection that can be extended continuously. This collection represents an important basis for further quantitative and qualitative research. The authority perspective of this thesis explores viable alternatives for implementing the European web accessibility quality mark in Austria. A look-ahead approach is applied that assumes the release of a normative document and an evaluation methodology in the near future. A scenario analysis includes the development of four scenarios and their evaluation in terms of six criteria. Moreover, a flexible business model for an Austrian web accessibility quality mark that fits into a possible European framework and at the same time facilitates and accelerates national implementation is introduced.
